Azure Managed Applications overview
Azure Managed Applications enable you to offer cloud solutions that are easy for customers to deploy and operate. You implement the infrastructure and provide ongoing support. To make a managed application available to all customers, publish it in Azure Marketplace. To make it available to only users in your organization, publish it to an internal catalog.
A managed application is similar to a solution template in Azure Marketplace, with one key difference. In a managed application, the resources are deployed to a resource group that's managed by the publisher of the app. The resource group is present in the customer's subscription, but an identity in the publisher's tenant has access to the resource group. As the publisher, you specify the cost for ongoing support of the solution.
The documentation for Azure Custom Providers used to be included with Managed Applications. That documentation was moved to Azure Custom Providers.
Advantages of managed applications
Managed applications reduce barriers to customers using your solutions. They don't need expertise in cloud infrastructure to use your solution. Customers have limited access to the critical resources and don't need to worry about making a mistake when managing it.
Managed applications enable you to establish an ongoing relationship with your customers. You define terms for managing the application and all charges are handled through Azure billing.
Although customers deploy managed applications in their subscriptions, they don't have to maintain, update, or service them. You can make sure that all customers are using approved versions. Customers don't have to develop application-specific domain knowledge to manage these applications. Customers automatically acquire application updates without the need to worry about troubleshooting and diagnosing issues with the applications.
For IT teams, managed applications enable you to offer pre-approved solutions to users in the organization. You know these solutions are compliant with organizational standards.
Managed applications support managed identities for Azure resources.
Types of managed applications
You can publish your managed application either internally in the service catalog or externally in Azure Marketplace.
The service catalog is an internal catalog of approved solutions for users in an organization. You use the catalog to meet organizational standards and offer solutions for the organization. Employees use the catalog to find applications that are recommended and approved by their IT departments. They see the managed applications that other people in their organization share with them.
For information about publishing a managed application to a service catalog, see Quickstart: Create and publish a managed application definition.
Vendors who want to bill for their services can make a managed application available through Azure Marketplace. After the vendor publishes an application, it's available to users outside their organization. With this approach, a managed service provider (MSP), independent software vendor (ISV), or system integrator (SI) can offer their solutions to all Azure customers.

Resource groups for managed applications
Typically, the resources for a managed application are in two resource groups. The customer manages one resource group, and the publisher manages the other resource group. When the managed application is defined, the publisher specifies the levels of access. The publisher can request either a permanent role assignment, or just-in-time access for an assignment that's constrained to a time period.
Restricting access for data operations is currently not supported for all data providers in Azure.
The following image shows the relationship between the customer's Azure subscription and the publisher's Azure subscription. The managed application and managed resource group are in the customer's subscription. The publisher has management access to the managed resource group to maintain the managed application's resources. The publisher places a read-only lock on the managed resource group that limits the customer's access to manage resources. The publisher's identities that have access to the managed resource group are exempt from the lock.
Application resource group
This resource group holds the managed application instance. This resource group may only contain one resource. The resource type of the managed application is Microsoft.Solutions/applications.
The customer has full access to the resource group and uses it to manage the lifecycle of the managed application.
Managed resource group
This resource group holds all the resources that are required by the managed application. For example, this resource group contains the virtual machines, storage accounts, and virtual networks for the solution. The customer has limited access to this resource group because the customer doesn't manage the individual resources for the managed application. The publisher's access to this resource group corresponds to the role specified in the managed application definition. For example, the publisher might request the Owner or Contributor role for this resource group. The access is either permanent or limited to a specific time.
When the managed application is published to the marketplace, the publisher can grant customers the ability to perform specific actions on resources in the managed resource group. For example, the publisher can specify that customers can restart virtual machines. All other actions beyond read actions are still denied. Changes to resources in a managed resource group by a customer with granted actions are subject to the Azure Policy assignments within the customer's tenant scoped to include the managed resource group.
When the customer deletes the managed application, the managed resource group is also deleted.
Managed applications use the
Microsoft.Solutions resource provider with ARM template JSON. For more information, see the resource types and API versions.
You can apply an Azure Policy to audit your managed application. You apply policy definitions to make sure deployed instances of your managed application fulfill data and security requirements. If your application interacts with sensitive data, make sure you've evaluated how that should be protected. For example, if your application interacts with data from Microsoft 365, apply a policy definition to make sure data encryption is enabled.
