EC2 Launch Configurations Deprecation Notice - Clarification Needed


I rec'd the notice regarding the deprecation of Launch Configurations at the end of 2022.

The notice states that:

You can continue using launch configurations, and AWS is committed to supporting applications you have already built using them, but in order for you to take advantage of our most recent and upcoming releases, a migration to launch templates is recommended. Additionally, we plan to no longer support new instance types with launch configurations by the end of 2022.

Does this mean that my ability to use and create new Launch Configurations will continue to work as they do now, but only that any new instance types that are introduced in the future are not supported? By "type" I assume that means a new instance type class that currently doesn't exist (e.g. "t3b").

Thanks for your help!

  • I was about to post this very question. I'm 99% sure that your interpretation is correct but it still feels ambiguous. I just want to be absolutely sure that my current launch configs that use the t3 nitro instances will continue to scale.

    Edit* This section of the notice seems to be more clear:

    December 31, 2022

    • No new EC2 features or new EC2 instance types will be added to launch configurations after this date.

    I think it safe to say current instance types will function just fine.

You understanding is correct.

Existing accounts will be able to use launch configurations with EC2 instance types that were available and launched prior to December 31, 2022. You can run and scale these workloads just like you would do prior to December 31, 2022.

After December 31, 2022 AWS will not be adding new EC2 instance type support to launch configurations. To use new instance types in your Auto Scaling group, you will need to employ launch templates. All new EC2 instance types will be made available and supported in launch templates.
