AWS services such as ECS Fargate let you specify an upper bound to the number of instances that can possibly be spawned.

There is even a default 'task limit' they enforce which we had to increase by sending an email request.

Typically though, as in the article above, it's the database service scaling that causes big shocks.

Rule of thumb would be to always ask if there is an upper bound to every cloud service one uses.

you can have auto scaling limits on ASGs on EC2. again, the technical solutions are there. it's a matter of learning how to use it properly
