Cloud Services (extended support) Is Now Generally Available

Cloud Services (extended support) is a new ARM-based deployment model for Azure Cloud Services.

Recently, Microsoft announced the GA release of Cloud Services (extended support), which is a new ARM-based deployment model for Azure Cloud Services.

Cloud Services (extended support) gives you the primary benefit of regional resiliency along with feature parity with Azure Cloud Services deployed using ASM. The solution also offers some ARM capabilities like RBAC, tags, private link support, policy, and use of deployment templates.

Starting with this release the ASM-based deployment model for Cloud Services will be called Cloud Services (classic). Users retain the control to build and rapidly deploy web and cloud applications and services. As a customer, you will also be able to scale cloud services infrastructure based on current demand and ensure that the performance of applications can keep up while simultaneously reducing costs.

Cloud Services (extended support) provides two paths to migrate from ASM to ARM - Re-deploy, and In-place migration. So, either you can deploy a new cloud service directly in ARM and then delete the old cloud service in ASM after thorough validation, or can make use of Migration tool which offers a seamless, platform orchestrated migration of existing Cloud Services (classic) deployments to Cloud Services (extended support).

The release also supports two types of roles, web and worker. There are no changes to the design, architecture, or components of web and worker roles.

As per announcement Azure GuestOS releases and associated updates are aligned with Cloud Services (classic). And, underlying update process with respect to update domains, rollback, and allowed service changes during an update will not change.
