Today, Amazon Elastic Container Service (Amazon ECS) launched a new management console. You can now create, edit, view, and delete Amazon ECS services and tasks, and view ECS clusters in fewer simpler steps. You can also learn about ECS capabilities and discover your ECS resources quickly and easily in the new console, as well as switch back to the existing console if needed. The new console will be continuously updated until all functionality from the existing console is available, and both consoles will be available to use until this time.
