Is there a way to spin up a new instance programmatically and direct a request there?

Question

I have an app which typically runs on 1 front end instance of class F1. The app receives files, saves them to blobstore, does something with them and sends them back. Sometimes the file is too large and I get

Exceeded soft private memory limit with 161.812 MB after servicing 1003 requests total

One way to solve this problem is to start running F2 instances. However, this would be a bit of an overkill because the very large files are sent once or twice a week - so the cost of running F2 would outweigh the benefit. One solution I can think of is to somehow programmatically direct all of these "receive file" requests to a new instance of its own, thereby giving it more memory to work with.

Answer 1

Seems like a pretty good use-case for a 'backend'
