Hi, the article is quite inspiring. Somehow I find this a bit confusing as CodePipeline provides two methods when it comes to ECS deployment, one being ECS, and the other ECS blue/green with CodeDeploy.

What exactly are the differences between those tow? I’ve tried ECS deployment (not ECS blue/green) once, and turns out I don’t need to supply an appspec.yml to get the pipeline work through the whole process

Thanks
