Sometimes, the instances fail under the ECS container cluster, and we have to manually go and find out the black sheep in the ECS container instance.
We had an issue earlier where one of the instances under the ECS container cluster went down, and we were not able to identify that instance. The instance got terminated, but a new instance did not come up. Therefore, I had to manually get that instance up. It could be optimized better. In production, we normally cannot sustain such things. It can be optimized in terms of instances, durability, and serving the requests of customers.
