Why aws new console ui for ecs not provide blue green deployment option?

Hi,

You can refer to this blog, which states:

The new console will become the default starting January 2023. We’re taking an iterative approach to add new features based on customers’ feedback. While we work to bring parity between the two consoles, both will exist in parallel. If you rely on one of the few features that have not yet transitioned to the new console, then please continue to use the previous console experience and send us feedback with what features are missing. Starting 2023, you can toggle back to the classic console similar to how you opt-in to the new console today.

If you want to use the old version, please toggle back the "New ECS Experience" on the left panel of the Console (similar to the screenshot below).

However, you should note:

The classic Amazon ECS console is reaching the end of life and will no longer be available after December 4, 2023. We recommend that you switch immediately to the new Amazon ECS console for a better experience. To learn more about the new Amazon ECS console experience, visit the documentation page, and you can also review and follow the new Amazon ECS console roadmap on GitHub.

Please let me know if you are unclear about anything.

Regards,
Atul
