We will break down the core components of vRealize Automation 8.x, explore the exam objectives in detail, and walk through the essential skills you need to master. From initial installation and infrastructure configuration to advanced blueprinting, extensibility, and troubleshooting, this series will provide a structured roadmap for your study plan. Our goal is to equip you with the knowledge and confidence needed to tackle the hands-on lab and successfully achieve this elite certification.
To succeed in the 3V0-31.21 exam, it is crucial to understand that vRealize Automation 8.x is a complete architectural redesign compared to its predecessor, vRA 7.x. The older version was built on a Windows-based IaaS model with a monolithic vApp for the control plane. This architecture, while powerful for its time, presented challenges in terms of scalability, resilience, and modern development practices. Recognizing these limitations, VMware re-engineered the platform from the ground up for the cloud-native era, and you must understand the implications of this shift.
The most significant change in vRA 8.x is its new architecture, which is based on a containerized microservices model running on a Kubernetes cluster. This modern foundation provides immense benefits in terms of scalability, high availability, and easier patching and upgrading. All the core services of the platform run as pods within this Kubernetes environment, which is managed by the vRealize Automation appliance itself. A working knowledge of basic Kubernetes concepts, such as pods and services, can be extremely helpful when troubleshooting the platform, a skill often tested in the 3V0-31.21 exam.
This architectural shift brought with it a complete re-imagining of the core product components. The monolithic platform of vRA 7.x was deconstructed into several distinct, integrated services. VMware Cloud Assembly became the new engine for blueprinting and infrastructure management, replacing the old design canvas. VMware Service Broker was introduced as the user-facing service catalog, providing a simplified consumption experience. Finally, VMware Code Stream was integrated to provide pipeline and release automation capabilities, aligning the platform with modern DevOps practices.
Understanding this evolution is not just a history lesson; it's fundamental to your preparation for the 3V0-31.21 exam. The logic, terminology, and workflows in vRA 8.x are entirely different from vRA 7.x. The exam will test your ability to work natively within this new paradigm. You must be comfortable with the microservices architecture, the roles of the different services, the YAML-based blueprinting language, and the new methods for extensibility. Grasping this foundational shift is the first and most important step towards mastering the platform.
The vRealize Automation 8.x platform is a suite of integrated products that work together to deliver a comprehensive cloud management solution. For the 3V0-31.21 exam, you must have a clear understanding of each component and its specific role. The entire suite is typically deployed and managed by vRealize Suite Lifecycle Manager (vRSLCM). vRSLCM is responsible for the installation, patching, upgrading, and content management of vRealize Automation and other products in the vRealize Suite. Your journey with vRA often begins and ends with vRSLCM.
Authentication and authorization for the entire platform are handled by VMware Identity Manager, now known as Workspace ONE Access. This component provides single sign-on (SSO) capabilities and serves as the central point for managing users, groups, and role-based access control. It integrates with enterprise directories like Microsoft Active Directory to synchronize user identities. Proper configuration of Workspace ONE Access is a critical first step in any deployment, as it controls who can log in and what they are permitted to do within the different vRealize Automation services.
The heart of the platform consists of three core services. Cloud Assembly is where cloud administrators and architects define and manage the infrastructure endpoints (Cloud Accounts), resource groupings (Cloud Zones), and governance policies (Projects). It is also home to the declarative YAML-based canvas used to author infrastructure-as-code blueprints. Service Broker consumes the content created in Cloud Assembly (and other sources) and presents it as a curated catalog of IT services to end-users. It is where you apply user-facing policies, such as lease times and approvals.
Code Stream is the component dedicated to CI/CD (Continuous Integration/Continuous Delivery) and release automation. It enables DevOps teams to create pipelines that can build, test, and deploy applications and infrastructure. Finally, vRealize Orchestrator (vRO) continues to play a vital role. A powerful vRO instance is embedded within every vRA appliance, providing advanced workflow automation capabilities for complex, stateful integrations. The 3V0-31.21 exam will require you to demonstrate proficiency across all of these interconnected components, showing you can manage the platform as a cohesive whole.
The most important document for your exam preparation is the official VMware Exam Guide, also known as the exam blueprint. This document is your roadmap, detailing every objective and skill that you could be tested on. The 3V0-31.21 exam is typically organized into sections that follow the logical lifecycle of the product. These sections often include Installation, Configuration and Management, and Troubleshooting. You should structure your study plan to align directly with these sections and their corresponding objectives.
Pay close attention to the verbs used in the exam objectives, such as "install," "configure," "manage," "troubleshoot," and "differentiate." These verbs give you a clear indication of the level of knowledge and skill required for each topic. "Configure" implies that you must be able to perform the task hands-on, navigating the UI or CLI to achieve a specific outcome. The blueprint is not just a list of topics to read about; it is a list of tasks you must be able to perform efficiently and accurately.
The format of the 3V0-31.21 exam is what sets it apart. It is a live, hands-on lab environment where you are presented with a series of tasks to complete within a set amount of time. You will be working on a real vRealize Automation deployment. This means you cannot rely on memorization alone. You must have the muscle memory and practical experience to navigate the product, locate the correct configuration screens, and solve problems as they arise. Time management is critical, as some tasks are complex and may have multiple dependencies.
The blueprint for the 3V0-31.21 exam explicitly states that the focus is on practical deployment and configuration skills. This means you should spend the majority of your study time in a lab environment. Reading books and watching videos is helpful for understanding concepts, but nothing can replace the experience of actually building, configuring, and breaking a vRealize Automation environment. Use the exam objectives as a checklist for your lab exercises. For each objective, perform the corresponding task in your lab until you can do it without hesitation.
A significant portion of the 3V0-31.21 exam often revolves around the initial installation and configuration of the vRealize Automation platform. VMware provides a streamlined tool for this purpose called the vRealize Easy Installer. This is a wizard-driven application that you run from a workstation, which automates the deployment of vRealize Lifecycle Manager, Workspace ONE Access, and vRealize Automation itself. You must be intimately familiar with this installer and the entire deployment process.
Before you even launch the installer, meticulous preparation of the environment is required. This is a common area where installations fail and a key skill to demonstrate on the 3V0-31.21 exam. You must ensure all prerequisites are met. This includes creating all necessary forward and reverse DNS records for the appliances, synchronizing time with a reliable NTP server, and having all the required service accounts and passwords ready. Any mistake in these prerequisite steps can cause the entire deployment to fail, forcing you to start over.
The Easy Installer guides you through several stages. First, you deploy vRealize Suite Lifecycle Manager (vRSLCM). Once vRSLCM is online, the installer uses it to deploy Workspace ONE Access and then vRealize Automation. You will be prompted to provide network information, appliance configurations, and passwords for all components. The wizard validates your inputs before proceeding, but it's crucial to enter everything correctly the first time. Understanding the sequence of events and the role of each component during installation is fundamental.
Even with the wizard, deployments can encounter issues. Common pitfalls include incorrect DNS or NTP settings, insufficient resources on the vSphere cluster, or network connectivity problems preventing the appliances from communicating. A key skill for the 3V0-31.21 exam is not just knowing how to run the installer, but also knowing how to troubleshoot a failed installation. This involves knowing where to find the relevant log files, how to interpret common error messages, and the steps to clean up a failed attempt before retrying.
Once your vRealize Automation instance is deployed and running, the first administrative task is to connect it to your infrastructure endpoints so it can manage and provision resources. This is accomplished through the concept of Cloud Accounts, which is a foundational topic for the 3V0-31.21 exam. A Cloud Account is simply a set of credentials and connection information for an endpoint like vCenter Server, AWS, Azure, or Google Cloud Platform.
For a vSphere-based environment, the process involves adding a vCenter Server Cloud Account within Cloud Assembly. You will need to provide the vCenter's fully qualified domain name or IP address, along with credentials for a service account that has the necessary privileges to discover resources and perform provisioning tasks. It is critical to ensure that this service account has the correct permissions assigned at the vCenter level, as insufficient privileges are a common cause of integration problems.
After the Cloud Account is added, vRealize Automation will initiate a data collection process. This process inventories all the compute resources (clusters, hosts), storage resources (datastores), and networks available within that vCenter. These discovered resources are not immediately available for consumption. They must first be organized and assigned to Cloud Zones. A Cloud Zone is a logical grouping of infrastructure resources that share specific characteristics or capabilities. For example, you might create a Cloud Zone for a specific vSphere cluster or a particular datastore cluster.
Cloud Zones are the bridge between the physical infrastructure and the governance layer. They allow you to control which resources are available for provisioning. You can tag zones based on their environment (e.g., "dev," "prod") or performance tier (e.g., "gold," "silver"). These tags are then used in blueprints to direct deployments to the appropriate infrastructure. Mastering the relationship between Cloud Accounts, data collection, and the configuration of Cloud Zones is an absolutely essential skill for the 3V0-31.21 exam.
A secure and well-managed cloud automation platform begins with robust identity and access management (IAM). In vRealize Automation 8.x, this is handled by Workspace ONE Access (formerly VMware Identity Manager). You must be proficient in its configuration for the 3V0-31.21 exam. Workspace ONE Access acts as the central authentication broker, providing single sign-on for all vRA services and managing the user and group lifecycle.
The most common initial IAM task is to integrate Workspace ONE Access with your corporate directory, which is typically Microsoft Active Directory. You can configure this integration using either LDAP or Integrated Windows Authentication (IWA). You will need to provide connection details for your domain controllers, along with credentials for a service account that can read user and group information. Once connected, you can configure synchronization schedules to keep the user and group information in Workspace ONE Access up to date.
After synchronizing your enterprise groups, the next step is to assign roles and permissions. Access to the different vRealize Automation services (Cloud Assembly, Service Broker, etc.) is controlled by assigning users or groups to specific service roles. For example, to allow a user to author blueprints, you would add them to the Cloud Assembly Administrator or User role. To allow a user to request items from the catalog, you would add them to the Service Broker User role.
Properly configuring these roles is critical for enforcing the principle of least privilege and ensuring a secure, multi-tenant environment. The 3V0-31.21 exam will expect you to be able to create users, integrate with Active Directory, synchronize groups, and assign the correct roles to meet a given set of requirements. You should also be familiar with configuring branding and login policies within Workspace ONE Access to customize the user experience. A misconfigured IAM system can prevent users from logging in or performing their required tasks, making this a critical area of expertise.
VMware vRealize Cloud Assembly is the engine room of the entire vRealize Automation platform. It is the service where cloud administrators and architects build, design, and manage the multi-cloud infrastructure fabric. For the 3V0-31.21 exam, a deep and practical mastery of Cloud Assembly is not just recommended; it is absolutely essential. This service is where you will spend a significant amount of your time during the exam, performing tasks that range from infrastructure setup to complex blueprint creation.
The Cloud Assembly user interface is logically divided into several key tabs that you must be able to navigate with confidence. The Infrastructure tab is where you configure all your foundational components: Cloud Accounts, Cloud Zones, Projects, Network Profiles, and resource mappings. The Design tab contains the blueprinting canvas, where you will author your infrastructure-as-code templates using YAML. The Extensibility tab is where you manage integrations with vRealize Orchestrator and create Action-Based Extensibility (ABX) actions.
The overall workflow within Cloud Assembly follows a logical progression that you should internalize. First, you onboard your cloud endpoints by creating Cloud Accounts. Next, you organize the discovered resources into Cloud Zones and create Projects to govern who can use those resources. Then, you create abstract profiles for network, storage, flavor, and image mappings. With the infrastructure in place, you can then move on to designing blueprints. Finally, you can add extensibility actions to customize the lifecycle. The 3V0-31.21 exam will test your ability to execute tasks across this entire workflow.
Think of Cloud Assembly as the bridge between your underlying infrastructure and your end-users. It abstracts the complexities of the individual cloud platforms and provides a unified policy and design canvas. A key philosophy is the concept of "intent-based placement." You define the requirements in a blueprint, and Cloud Assembly's placement engine uses tags and policies to determine the best location to provision the workload. Understanding this core principle is vital to success.
The foundation of any Cloud Assembly configuration begins with defining the infrastructure that will be managed. We introduced Cloud Accounts and Cloud Zones in the previous section, but the 3V0-31.21 exam requires a deeper understanding of their advanced configuration. While vSphere is a common endpoint, you should also be familiar with the process of adding public cloud accounts for AWS, Azure, and Google Cloud Platform. Each cloud provider has unique requirements for authentication, such as using access keys for AWS or service principals for Azure.
Once a Cloud Account is configured, the detailed setup of Cloud Zones becomes critical. A Cloud Zone is more than just a grouping of compute resources; it is a policy enforcement point. Within a Cloud Zone's configuration, you can assign capability tags that describe the environment. For example, you could tag a zone with "pci-compliant:true" or "environment:production". These tags become the target for constraints in your blueprints, ensuring that workloads with specific requirements are placed on the appropriate infrastructure.
The crucial link between users and infrastructure is the Project. A Project is the primary unit of governance and tenancy within Cloud Assembly. When you create a Project, you bring together users or groups, and you assign them access to one or more Cloud Zones. This is how you control which teams can deploy to which parts of your infrastructure. For example, the Development team's Project might only have access to the "development" Cloud Zone, while the Production team's Project has access to both "development" and "production" zones.
Within a Project, you can also define specific governance rules. You can set resource quotas that limit the amount of CPU, memory, or storage that the Project's users can consume in total. You can also apply custom properties and naming conventions that will be enforced on all deployments from that Project. A thorough understanding of how Cloud Accounts, Cloud Zones, and Projects interrelate to form a comprehensive governance framework is a central theme of the 3V0-31.21 exam.
To create truly cloud-agnostic blueprints, you need to abstract the specific details of your underlying infrastructure. This is achieved through a set of profiles and mappings within Cloud Assembly, and you will be expected to configure these during the 3V0-31.21 exam. Flavor Mappings are used to define standardized compute sizes. Instead of specifying "2 vCPUs and 4GB of RAM" in a blueprint, you can simply request a "medium" flavor.
You create a Flavor Mapping by defining a standard name (e.g., small, medium, large) and then mapping that name to a specific instance size for each of your Cloud Zones. For a vSphere zone, "medium" might mean 2 vCPUs and 4GB of RAM. For an AWS zone, the same "medium" flavor could be mapped to a "t3.medium" instance type. This abstraction allows you to write a single blueprint that can request a "medium" machine, and Cloud Assembly will automatically deploy the correctly sized VM or instance based on the target cloud.
Similarly, Image Mappings are used to abstract operating system templates. You create a standard name for an image, such as "centos8" or "win2019-std," and then map that name to the actual VM template or machine image in each Cloud Zone. In your vSphere zone, "centos8" might point to a specific vSphere template. In your Azure zone, the same "centos8" name could be mapped to a CentOS 8 image from the Azure Marketplace.
Creating these generic, abstract mappings is fundamental to achieving the multi-cloud promise of vRealize Automation. They allow you to write a single blueprint that can be deployed across different cloud platforms without any modifications. The blueprint simply requests a generic flavor and image, and the mappings configured in the infrastructure layer handle the translation to the cloud-specific details. The 3V0-31.21 exam will undoubtedly require you to create and use flavor and image mappings to build portable blueprints.
Networking is a critical component of any application deployment, and Cloud Assembly provides a flexible framework for managing network configurations through Network Profiles. This is a key area of study for the 3V0-31.21 exam. A Network Profile brings together settings for a particular network, including subnet information, gateway, DNS, and tags. These profiles are then associated with a specific Cloud Account and region.
When configuring a Network Profile, you can define various network types. "Existing Network" is used to consume a network that is already configured in the underlying cloud platform, such as a vSphere port group or an AWS VPC subnet. You can also configure "On-Demand Networks," where vRA, often in conjunction with NSX-T, will dynamically create a new routed or private network segment specifically for the deployment. You can also configure security groups, either existing or on-demand, to act as a firewall for the deployed machines.
A major challenge in automated provisioning is IP address management (IPAM). Cloud Assembly provides several options to handle this. It has a built-in IPAM service that allows you to define IP ranges within a Network Profile. When a machine is provisioned using that profile, vRA will automatically allocate an available IP address from the defined range and release it upon decommissioning. This is suitable for smaller environments or proof-of-concept labs.
For enterprise environments, it's more common to integrate with an external, authoritative IPAM provider like Infoblox or a homegrown solution. Cloud Assembly supports this integration through its extensibility features. You can create an extensibility action that calls out to the external IPAM system's API to request an IP address during provisioning. The 3V0-31.21 exam will expect you to be able to configure Network Profiles for existing networks and understand how to manage IP addressing for your deployments, both with the internal service and through the concept of external integration.
The blueprinting canvas in vRealize Automation 8.x is a significant departure from previous versions. It is a fully declarative, code-based experience using the YAML (YAML Ain't Markup Language) format. Proficiency in reading, writing, and debugging YAML blueprints is arguably the most critical hands-on skill for the 3V0-31.21 exam. The canvas provides both a graphical design surface and a code editor, but a deep understanding of the underlying YAML structure is essential.
A basic blueprint for deploying a virtual machine has a simple, logical structure. It starts with a format version and a name. The core of the blueprint is the resources section, where you define the components you want to deploy. Each resource has a logical name and a type. For a vSphere virtual machine, the type would be Cloud.vSphere.Machine. Within the resource block, you define its properties under the properties key.
Essential properties for a virtual machine resource include image and flavor. These properties should reference the generic Image and Flavor Mappings you configured in the infrastructure layer. You also need to attach the machine to a network. This is done by adding a network interface card (NIC) resource of type Cloud.vSphere.NetworkInterface and connecting it to a network defined in a Network Profile. This declarative model, where you define the "what" and not the "how," is a core principle of Infrastructure as Code (IaC).
To make blueprints reusable and user-friendly, you can define inputs. The inputs section at the top of the blueprint allows you to declare variables that the user can provide when they request the catalog item. For example, you could create an input for the deployment name or for the machine's CPU count. You can then reference these inputs elsewhere in the blueprint using the syntax ${input.variableName}. Mastering the basic structure of a YAML blueprint and the use of inputs is the first step towards tackling more advanced scenarios on the 3V0-31.21 exam.
Once you have mastered the basics of a single-machine blueprint, the 3V0-31.21 exam will expect you to be able to implement more advanced and realistic scenarios. This includes creating blueprints that deploy multi-tier applications. A multi-machine blueprint simply involves defining multiple machine resources in the resources section of the YAML. For example, you could define a web server resource and a database server resource within the same blueprint.
Often, you will need to provision additional storage for your machines. You can add a disk resource of type Cloud.vSphere.Disk to your blueprint. In its properties, you define its size in gigabytes. You then attach it to a virtual machine by adding an attachedDisks property to the machine resource, referencing the logical name of the disk resource. You can also use tags and constraints to control which datastore the disk is placed on.
Guest operating system customization is a critical part of the provisioning process. This is how you set the hostname, configure networking, and run initial setup scripts inside the newly deployed machine. vRealize Automation uses cloud-init for Linux machines and Sysprep for Windows machines to perform this customization. You can pass configuration data to these tools using a property called cloudConfig in your blueprint. Here, you can write cloud-init or Sysprep scripts directly in YAML to perform tasks like creating users, installing packages, or running commands.
For deploying multiple identical instances, such as a cluster of web servers, you can use the count property on a resource. Setting count: 3 on a machine resource will cause vRA to provision three identical copies of that machine. You can then use variables and expressions to give each one a unique name. Leveraging these advanced techniques—multi-machine designs, attached storage, guest customization with cloudConfig, and the count property—allows you to create powerful, dynamic blueprints that model real-world applications, a key competency for the 3V0-31.21 exam.
We've discussed Projects as the link between users and infrastructure, but they are also the primary point for policy enforcement and governance. A deep dive into the governance capabilities of Projects is essential for the 3V0-31.21 exam, as you will likely be asked to configure them to meet specific business requirements. As a reminder, a Project is the entity that brings together users, infrastructure (via Cloud Zones), and governance rules.
One of the most important governance features within a Project is the ability to set resource quotas. You can define hard limits on the amount of CPU (in cores), memory (in GB), and storage (in GB) that can be consumed by all deployments within that Project. You can also limit the number of virtual machines. These quotas are enforced at request time. If a user tries to deploy a blueprint that would exceed the Project's quota, the request will fail. This is a critical feature for managing resource consumption in a multi-tenant environment.
Projects are also where you can apply constraints and custom properties that affect all deployments. For example, you can add a constraint tag to a Project, such as "environment:dev". This tag will be added to every deployment request from that Project, ensuring that the workloads can only be placed on a Cloud Zone that also has the "environment:dev" tag. This is a powerful way to enforce placement logic without having to hardcode it into every single blueprint.
Furthermore, you can define Project-level custom properties. A common use case for this is to assign a cost center code to a Project. This property will then be attached to every machine deployed by that Project, which can be used for reporting and chargeback purposes. The combination of user and zone assignments, resource quotas, and constraint-based placement policies makes the Project the central point for applying governance in Cloud Assembly. You must be able to configure all these aspects for the 3V0-31.21 exam.
While Cloud Assembly is the powerful engine for infrastructure design and management, VMware vRealize Service Broker provides the friendly, user-facing storefront. Its primary role is to aggregate IT services from multiple sources into a single, unified catalog, simplifying how end-users consume those services. For the 3V0-31.21 exam, you must demonstrate your ability to configure Service Broker to provide a seamless and governed consumption experience. It transforms complex blueprints and workflows into simple, requestable catalog items.
The core function of Service Broker is to abstract the underlying complexity of the provisioning source. To an end-user, requesting a virtual machine from vSphere, an S3 bucket from AWS, or a complex multi-tier application should all be a similar, straightforward experience. Service Broker achieves this by providing a single portal where users can browse, request, and manage their deployed services, regardless of the technology that provisions them in the background. This is a key part of delivering a true cloud-like experience to your organization.
Your first tasks in Service Broker will involve configuring content sources and then importing content to make it available in the catalog. The most common content source is, of course, Cloud Assembly. You will create a connection to Cloud Assembly and then choose which blueprints to import into the Service Broker catalog. Once imported, you can manage the visibility of these catalog items by sharing them with specific Projects, ensuring that users only see the services they are authorized to request.
Beyond just presenting a catalog, Service Broker is also where you can customize the user experience. You can organize catalog items with custom icons to make them more visually appealing and easier to identify. More importantly, you can create custom forms to simplify the request process for complex blueprints. This ability to transform a powerful backend blueprint into a simple, user-friendly frontend catalog item is a critical skill that the 3V0-31.21 exam will test.
A key feature of Service Broker is its ability to aggregate content from a variety of sources, not just Cloud Assembly. A solid understanding of how to configure these different content sources is crucial for the 3V0-31.21 exam. Besides Cloud Assembly blueprints, you can also import native AWS CloudFormation templates, allowing you to offer and govern the deployment of AWS-native services through the same catalog. This is a powerful feature for organizations with a multi-cloud strategy.
Another important content source is vRealize Orchestrator (vRO). You can import any vRO workflow into the Service Broker catalog. This allows you to expose complex automation tasks as requestable services. For example, you could have a workflow that performs a user-onboarding process or a complex storage LUN creation task. By importing it into Service Broker, you can put a friendly face on that automation, allowing users to run it in a controlled and governed manner without needing to understand the underlying workflow logic.
Once you have content in your catalog, you must apply governance policies to control how it is consumed. This is a major focus of Service Broker and a likely topic on the 3V0-31.21 exam. Lease Policies are used to define the maximum lifespan of a deployment. You can set a policy that states all "development" deployments must expire after 30 days, after which they are automatically destroyed. This prevents resource sprawl and helps control costs.
Day 2 Action Policies control which post-provisioning operations are available to users for their deployments. For example, you can create a policy that allows users to reboot or snapshot their machines but prevents them from resizing or deleting them. Approval Policies are another critical governance mechanism. You can create a policy that requires a manager's approval for any deployment that exceeds a certain cost or size. Mastering these different policy types is key to building a well-governed cloud consumption platform.
While blueprints can be made dynamic using inputs, presenting a user with a long list of text boxes and dropdowns can be intimidating and confusing. Service Broker's custom forms feature allows you to create a much more intuitive and guided request experience. The 3V0-31.21 exam will expect you to be able to use the custom form designer to enhance the usability of your catalog items. This feature directly addresses the need to make powerful automation accessible to a broader audience.
The custom form designer is a drag-and-drop interface that allows you to completely remodel the request form for any catalog item. You can rearrange fields, group them into sections or tabs, and add descriptive text and labels. This allows you to create a logical flow that makes sense to the user. For example, you can have a "Basic Information" tab with the deployment name and a "Networking" tab with the network selection options, rather than presenting everything as a single long list.
Beyond just aesthetics, you can add powerful logic to your custom forms. You can add validation rules to ensure that user inputs meet certain criteria, such as a hostname matching a specific naming convention. You can also create visibility constraints, where the answer to one question determines whether another question is shown. For instance, selecting a "Windows" OS could reveal a field for a license key, while selecting "Linux" would hide it.
For even more dynamic forms, you can use vRealize Orchestrator actions to populate form fields with data from external systems. For example, you could have a dropdown menu for "Cost Center" that is dynamically populated by calling a vRO action that queries your company's financial database. This ability to create intelligent, dynamic, and user-friendly request forms is a critical part of delivering a polished service catalog and is a skill you should practice thoroughly for the 3V0-31.21 exam.
Modern IT practices are heavily influenced by DevOps principles, and vRealize Automation embraces this with the inclusion of vRealize Code Stream. Code Stream is a release automation and continuous delivery tool that is an integral part of the vRA suite. For the 3V0-31.21 exam, you should have a foundational understanding of Code Stream's purpose and be able to construct a basic pipeline. It allows you to automate the entire lifecycle of your application and infrastructure code, from development to production.
To understand Code Stream, you must be familiar with its key concepts. Endpoints are the connections to your external tools, such as your source code repository (e.g., Git), your CI server (e.g., Jenkins), your container registry, or your Kubernetes cluster. A Pipeline is the visual representation of your release process, which is composed of one or more Stages. Each Stage contains a series of Tasks that are executed sequentially or in parallel. A Task is the smallest unit of work, such as running a script, deploying a blueprint, or waiting for an approval.
Code Stream helps bridge the gap between application developers and infrastructure teams. It can be used to create Continuous Integration (CI) pipelines, which automatically build and test code every time a developer commits a change. It can also be used for Continuous Delivery (CD), where successfully tested code is automatically deployed to a staging or production environment. This automation accelerates the delivery of new features and improves the reliability of the release process.
A key use case for Code Stream within the context of vRealize Automation is Infrastructure as Code (IaC). You can create a pipeline that automatically triggers the deployment of a vRA blueprint. For example, a pipeline could first provision a new server using a Cloud Assembly blueprint and then, in a subsequent stage, deploy the latest version of an application onto that server. This ability to orchestrate both infrastructure and application deployment in a single pipeline is a powerful concept you should be familiar with for the 3V0-31.21 exam.
The 3V0-31.21 exam may require you to demonstrate your understanding of Code Stream by building a functional pipeline. Let's walk through the steps for creating a simple yet practical pipeline that deploys a Cloud Assembly blueprint. The first step is always to configure your Endpoints. For an IaC pipeline, you would typically need a Git endpoint to connect to your source code repository where your blueprint YAML files are stored, and a vRA endpoint to connect to Cloud Assembly.
With your endpoints in place, you can start designing the pipeline. You would create a new pipeline and add a Stage, perhaps named "Deploy Dev Environment." Inside this stage, you would add a Task. Code Stream offers many different task types. For this use case, you would select the "vRA" task type. In the task's configuration, you would specify the action to perform, which in this case would be "Deploy Blueprint."
You would then configure the details of the vRA task. You would select the vRA endpoint you created earlier and specify which Cloud Assembly blueprint you want to deploy. You can either choose a blueprint that is already in vRA or, more powerfully, you can have the pipeline pull the blueprint's YAML code directly from your Git repository. You would also provide any necessary input parameters for the blueprint, which can be hardcoded, user-provided, or derived from previous tasks in the pipeline.
Once the pipeline is designed, you can trigger it manually or set up a trigger that automatically runs the pipeline whenever a change is committed to your Git repository. As the pipeline runs, you can monitor its progress in the Code Stream UI. You can see which stages and tasks are running and view the logs for each task. If a task fails, the pipeline will stop, and you can investigate the issue. The ability to create, execute, and monitor a basic infrastructure deployment pipeline is a key practical skill.
No automation platform can meet every possible requirement out of the box. Extensibility is the mechanism by which you can customize and extend the platform's behavior to integrate with other systems and perform custom tasks. In vRealize Automation 8.x, the primary method for this is Action-Based Extensibility (ABX). Understanding ABX is critical for the 3V0-31.21 exam. ABX provides a modern, serverless-style framework for running small scripts in response to lifecycle events.
ABX is a significant shift from the traditional, workflow-based extensibility of vRA 7.x. Instead of building complex, stateful workflows in vRealize Orchestrator, you write short, stateless scripts, typically in Python or Node.js. These scripts, called ABX Actions, are executed in isolated containers on the vRA appliance itself or on an external Function-as-a-Service provider like AWS Lambda. This approach is often simpler and more lightweight for many common extensibility tasks.
To use ABX, you first create an Action. This involves writing your script and defining its inputs and dependencies. For example, you could write a Python script that uses the requests library to make a REST API call to an external system. Next, you create a Subscription. A subscription ties your Action to a specific event in the vRA lifecycle. You choose an event topic, such as "Compute post-provision," and then select your Action to be the callback.
Now, whenever that event occurs—in this case, after any virtual machine is successfully provisioned—vRA will automatically trigger your ABX Action. It will pass a payload of data about the event (like the name and IP address of the newly created VM) to your script as an input. Your script can then perform its custom logic, such as updating a record in a CMDB with the new VM's information. The ability to create an ABX action and subscribe it to a lifecycle event is a fundamental extensibility skill for the 3V0-31.21 exam.
While ABX is the modern and preferred method for many extensibility tasks, vRealize Orchestrator (vRO) remains a powerful and essential component of the vRealize Automation suite. Its relevance is still high, and you must understand its role for the 3V0-31.21 exam. Where ABX excels at short, stateless scripts, vRO is the master of complex, stateful, and long-running automation workflows that require intricate logic, user interaction, or integration with systems that have dedicated vRO plug-ins.
A full-featured vRealize Orchestrator instance is embedded directly within the vRA 8.x appliance, and it is integrated by default. You can access it directly through the vRA user interface. The process of using vRO for extensibility is very similar to ABX. You create a subscription to a lifecycle event, but instead of selecting an ABX action as the callback, you select a vRO workflow. vRA will then trigger that workflow whenever the subscribed event occurs, passing the event's data payload to the workflow's input parameters.
There are many scenarios where vRO is still the better choice over ABX. If you need to orchestrate a process that involves multiple steps with complex branching logic, loops, or error handling, a vRO workflow provides a much more robust framework than a simple ABX script. If you are integrating with a system like Active Directory, Infoblox, or ServiceNow, there are mature, pre-built vRO plug-ins that provide a rich library of ready-to-use workflow steps, saving you from having to write raw API calls yourself.
Another key use case for vRO is any workflow that requires user interaction. A vRO workflow can have user interaction steps that pause the workflow and wait for a user to provide input before proceeding. This is something that is not possible with a stateless ABX action. The 3V0-31.21 exam will expect you to understand the complementary nature of ABX and vRO and to be able to identify which tool is the right choice for a given extensibility requirement.
