Oh I disagree - we migrated from azure to AWS, and running a container on Fargate is significantly more work than Azure Container Apps [0]. Container Apps was basically "here's a container, now go".
Your link does seem to be a lot more "container, plus all the surrounding stuff" in line with the "apps" part, whereas mine more closely matches my actual experience of what you said: container, go
The "what the fucking hell is wrong with you people?" part is that their naming is just all over the place, and changes constantly, and is almost designed to be misleading in any sane conversation. I quite literally couldn't have guessed whether Container Apps was a prior name of Container Instances, a super set of it, subset, other? And one will observe that while I said Container Instances, and the URL says Container Instances, the ARM is Container Groups. Are they the same? different? old? who fucking knows. It's horrific
