It looks like Lambda functions are limited in complexity and runtime duration.

The way I see it is pairing it with the container service (ECS) and spawning containers in response to events, possibly spawning EC2 instances if you need more computer.

It looks like Lambdas can also be set to execute at a scheduled time, so you could make a delayed Lambda that would shut down any EC2 instances you spawned as well.
