I am developing the architecture of this application and the way we need to scale is not just stateless API requests, but it's a logical split of responsibilities. In other words, we may only be able to work on data 1-5 while we need another instance to work on 6-10. We will need an undefined number of instances and would like a manager to spin up and down EC2 instances as needed.
While scouring the web I am not able to come up with anything good, are there any good articles or is there a term for this? I have found IAC (Infrastrucure as Code) but from what I see that is simply deploying additional services, I don't see anything as IAC spun up from within the application. Is there a term for this?
