Helps to store Docker containers and images but deployment can be complex
If there were a way to use containers as tasks directly, that would simplify things. Currently, when we use EC2 instances, scaling horizontally means increasing the instance count by five times, which might not be cost-effective. Maybe using containers directly for tasks could be a better option. Setting up this product initially does take quite a bit of time, and maintaining it also requires effort. Doing it via command line would be challenging, so I find it easier to manage through the interface.
