ECS will always have the major disadvantage of strongly coupling your infrastructure and often your code to AWS. They will continue to make it more appealing to lock your software into their platform than to go with their thinner facilities for OSS, doing the minimum to keep up to date with trends in open source, just enough to lure you in and create “easier” paths until you can’t afford to leave. We have this problem with Azure - sure it’s easier to get a knucklehead to push buttons and get an app running, but after years you’ll be scrambling to reduce costs. Good luck with that when all of your terraforms use Azure Resource Manager and all of your source code uses Azure Functions. Being stuck with microsoft/amazon and a team of engineers who spent their time learning vendor-specific skills instead of the open source tech that enables it, sounds awful. |

Sure, you might be lucky with the engineers you have, they might be savvy enough to wrangle a couple of hosts for you. But are they backed up? what's the disaster recovery procedure like? How do you rotate keys/passcodes, how do you audit who has access?
Unless you are doing something wrong, your biggest costs are engineering time.
> disadvantage of strongly coupling your infrastructure and often your code to AWS.
you can say the same thing about any infrastructure. yes, you can migrate k8s from one physical host to another. But, for that to be effective, you need to not be using any manage services. So that means you're on the hook for all the painful things like DB state and recovery, messaging systems, etc,etc,etc.
Then you think as a business, what are you actually spending money to do? maintain the code that makes you money, or maintain the system underneath it, just in case you might need to move to save opex thats almost certainly going to be less than one engineer.
98% of companies have no issue with scale. They have issues with availability, features, backups, speed. exchanged 10% of an engineer's salary to never really have to deal with any of those issues is a good deal for most[1] companies
[1] most, but not all. However unless you are getting close to spending 1 engineer in AWS fees, moving to self hosting is nothing but premature optimisation.
