I was using Elastic Container Service (ECS) like I mentioned in my other comment. I first used it 3 years ago when it was still evolving, and in 2023 they turned off their launch configuration portion in favor of launch templates. I can't remember the exact details, but I think this covers it: https://sinovi.uk/articles/amazon-ec2-launch-configurations-will-deprecate-support-for-new-instances https://sinovi.uk/articles/amazon-ec2-launch-configurations-... My complaint is that all service providers should provide a migration wizard to convert to and from configurations that do basically the same thing. Frameworks like Laravel emphasize the importance of migrations for database schemas: https://laravel.com/docs/migrations https://laravel.com/docs/migrations I use that concept constantly in my work for backwards compatibility, but basically never see it from service providers, which I find sad and somewhat irresponsible or at least discourteous.
