Describe the difference between mainstream support and extended support for Azure services.

Last updated on 

Microsoft Azure follows a support lifecycle model that includes two main phases: Mainstream Support and Extended Support. Please note that there might have been changes or updates after my last training data, and it's advisable to check the official Azure documentation for the latest information.

  1. Mainstream Support:
    • Duration: Mainstream support typically lasts for a fixed number of years after the general availability of a product or service.
    • Scope: During this phase, customers receive regular updates, patches, and security fixes. It includes feature updates, non-security updates, and online support.
    • New Features: New features and enhancements are introduced regularly, and the platform is actively developed and supported.
    • End of Mainstream Support: At the end of the mainstream support phase, Microsoft may stop providing non-security updates, and new features might no longer be introduced.
  2. Extended Support:
    • Duration: Extended support comes into play after the mainstream support phase ends.
    • Scope: While the service continues to receive security updates during this phase, other types of updates, including feature updates and non-security updates, are limited.
    • Security Updates Only: Extended support is primarily focused on providing security updates to ensure that the service remains protected against known vulnerabilities.
    • End of Extended Support: Once extended support ends, Microsoft no longer provides any updates, including security updates. The product or service is considered deprecated, and customers are encouraged to migrate to a supported version.

In the context of Azure services, this support lifecycle is crucial for businesses to plan their infrastructure, updates, and migrations. It provides a clear roadmap for when to expect updates and when a service will no longer receive support. Businesses need to stay aware of these timelines to ensure the security and reliability of their applications and data.
