As a cloud administrator, you can create a Microsoft Azure cloud account for account regions to which your team will deploy vRealize Automation cloud templates.

vRealize Automation Microsoft Azure integrations support Azure Marketplace images. Users can specify an Azure Marketplace when they set up image mapping in Cloud Assembly. Cloud Assembly automatically picks up the plan information in any specified Marketplace image. When using Marketplace images, users must accept legal terms for plans in their Azure portal or an exception will occur when they try to deployment the cloud template and the deployment will fail.

To view an example use case of how Microsoft Azure cloud account works in vRealize Automation see WordPress end-to-end use case.

Prerequisites

Procedure

  1. Select Infrastructure > Connections > Cloud Accounts and click Add Cloud Account.
  2. Select the Microsoft Azure account type and enter credentials and other values.
  3. Select the appropriate Azure environment. The selection can be Azure Public Cloud, which is appropriate for most users, or it can be Azure US Government Cloud, which is valid for authorized government users.
  4. Click Validate.
    The account regions associated with the account are collected.
  5. Select the regions to which you want to provision this resource.
  6. For efficiency, click Create a Cloud zone for the selected regions.
  7. If you need to add tags to support a tagging strategy, enter capability tags. See How do I use tags to manage Cloud Assembly resources and deployments and Creating a tagging strategy.

    video symbolFor more information about how capability tags and constraint tags help control deployment placements, see the Constraint Tags and Placement video tutorial.

  8. Click Save.

Results

The account is added to vRealize Automation, and the selected regions are available for the specified cloud zone.

What to do next

Create infrastructure resources for this cloud account.

You can use availability sets or availability zones with an Azure cloud account, but not both.

When you add an Azure cloud account to a cloud template, you can choose to reuse availability sets if you want. Subscriptions have a limit of 2000 availability sets and 25,000 virtual machines, so it makes sense to reuse availability sets when possible. There are two YAML properties that you can use to control how deployments use availability sets. The availabilitySetName property enables you to specify an availability set to use. The second property is doNotAttachAvailabilitySet which is set to false by default. If this property is set to true, vRealize Automation will create the deployment with no availability set.

You cannot create a deployment without an availability set if you use a load balancer attached to the virtual machine.

The following table describes how vRealize Automation behaves depending on whether a resource group and an availability set are specified in the cloud template.

An availability set cannot exist without being part of a resource group. The availability sets in a given resource group must have unique names. Availability sets can have the same name only if they are part of different resource groups.

If you do not specify a resource group name, then vRealize Automation will create a new resource group, which means that a new availability set must also be created even if a name is passed. The new set will use the name that is passed.

Table 1.
Resource Group Specified Availability Set Specified Result
No No vRealize Automation creates a new resource group and a new availability set for the virtual machine.
Yes No vRealize Automation reuses the existing resource group and creates a new availability set for the virtual machine.
No Yes vRealize Automation creates a new resource group and a new availability set with the specified name.
Yes Yes vRealize Automation reuses the existing resource group. If an availability set with the specified name already exists in that group, it will also be reused. If there is no availability set with the specified name in the group, a new one is created with that name.

As an alternative, you can use availability zones with deployed Azure virtual machines rather than availability sets. If you use availability zones, you can specify an Azure availability zone for a provisioned machine, either by tagging compute resources or by using restrictions expressed through flavor mapping.

This feature enables users to provision a machine in an Azure availability zone by tagging the computes, or selecting the flavor mapping that contains the desired availability zone.

If you want to use availability zones for an Azure virtual machine, you must explicitly pass the attachAvailabilityZone boolean property set to true in the cloud template for the cloud account as shown in the following cloud template snippet. 

format version: 1
inputs: {}
resources:
   Cloud_Aure_Machine_1:
   type: Cloud Azure Machine
   properties:
     image: ubuntu
     flavor: small
     attachAvailabilityZone: true

If this property is not present, no availability zone are used for the provisioned machine; instead, an availability set is created. If this property is present and set to true, you can select the desired availability zone on the Compute tab of the cloud zone.

If availability zones are used in a cloud account, the IP SKU type and IP allocation method will be Static and the PublicIPAddress sku type is limited to Standard. Also, not all availability zones are supported for every flavor in every region. The following table outlines the regions that support selection of availability zones. Note that each of the supported regions has three zones. Each region in the table should support Azure availability zones, but depending on the selected size in the flavor mapping, it can be restricted to only one zone.

If you want to use machine provisioning in an availability zone and later have a working ssh to the machine, you must first have a correctly configured network security group, with enabled ssh, in the Azure portal. In addition, you must create a network profile with the enumerated data for the network and security groups and then use this network profile on provisioning.

Cloud Assembly supports Azure disk snapshots for deployed virtual machines. See Working with snapshots for Microsoft Azure virtual machine disks in vRealize Operations Manager for more information.

Cloud Assembly supports several boot diagnostics options for Azure deployments. Boot diagnostics supports debugging of Azure virtual machines and includes collection of log information and relevant screen shots. See Using boot diagnostics and log analytics with a Microsoft Azure virtual machine for more information.

In addition to standard disk options, Azure integrations supports selection of Azure performance disk types for users of Azure SSD Premium managed disks. This feature enables users to maximize performance as needs demand. Not all performance disk configurations are supported. See https://learn.microsoft.com/en-us/azure/virtual-machines/disks-change-performance for more information about supported configuations.

You can configure the performance disk type during deployment configuration using the performanceTierType property in your cloud template. The following example demonstrates a potential implementation.

formatVersion: 1 
inputs: {}
resources:
  Cloud_Azure_Disk_1:
    type: Cloud.Azure.Disk
    properties:
      capacityGb: 2
      managedDiskType: Premium SSD
      performanceTier: P1
