What are the prerequisites for a Microsoft Azure SaaS subscription?

This article explains the essential prerequisites and requirements for subscribing to and using Microsoft Azure Software as a Service (SaaS) offerings. Ensuring these prerequisites are met will help you achieve a smooth deployment, configuration, and management experience for your Azure SaaS subscriptions.

Prerequisites for a Microsoft Azure SaaS Subscription

Before creating or using an Azure SaaS subscription, the following prerequisites should be met:

1. Active Azure Subscription

  • You must have an active Microsoft Azure subscription with billing enabled.
  • The user subscribing to the SaaS solution should have sufficient permissions, typically Owner or Contributor role on the subscription.
  • Ensure that your subscription is enabled to purchase resources from Azure Marketplace.

2. Required Azure Permissions

3. Register Required Azure Resource Providers

 Ensure the following Azure resource providers are registered in your subscription, as the SaaS solution depends on them:

  • Microsoft.Compute
  • Microsoft.Network
  • Microsoft.Storage
  • Microsoft.ManagedIdentity
  • Microsoft.SaaS

How to register resource providers using Azure CLI:

az provider register --namespace Microsoft.Compute
az provider register --namespace Microsoft.Network
az provider register --namespace Microsoft.Storage
az provider register --namespace Microsoft.ManagedIdentity
az provider register --namespace Microsoft.SaaS
 
For detailed guidance, see Microsoft’s official docs:
Install the Azure CLI: https://learn.microsoft.com/en-us/cli/azure/install-azure-cli
az provider register command: https://learn.microsoft.com/en-us/cli/azure/provider#az-provider-register

4. Azure Active Directory (Azure AD) Configuration

  • Ensure your Azure AD tenant is properly configured.
  • The user subscribing must belong to the same Azure AD tenant as the Azure subscription.
  • If your SaaS solution uses service principals or managed identities, verify they have the necessary role assignments.

5. Network and Security Requirements 

  • Configure your network and firewall to allow outbound access to the SaaS service endpoints.
  • If using private networks, ensure necessary access to Azure Marketplace and SaaS vendor endpoints.

6. Storage and Data Considerations 

  • Confirm adequate storage capacity and network bandwidth in your Azure environment.
  • Review your organization’s data retention and backup policies to align with the SaaS solution’s capabilities.

7. Billing and Licensing 

  • Review pricing, licensing, and billing terms of the SaaS offering before subscription.
  • Verify your Azure billing account supports Azure Marketplace purchases.
