I used ECS a couple years ago and I liked it way more than working with k8s now.

Could you delve into the Pro's and Cons of using ECS against K8s?

ECS was just so much simpler, but you had less switches and knobs you could manipulate. Our scale was much smaller (was for a US govt website, so looking at 10s or 100s of thousands of daily users, not millions), so at that scale we didn’t need the complexity.
