Every web framework allows handling multipart/form-data encoded content, but none of those allow for event-driven parsing on such data. Since I needed something like that for work, I ended up writing one and learned a cool new Python technology in the process.
In many ways, infrastructure as code makes a lot of sense. Especially when hosting provides are providing servers literally on-demand via their APIs.

In case your application is deployed on AWS-ELB and allows websocket connections, this post shows to handle load balancing and configure health checks.
PaaS is too much abstraction, not to mention expensive. Renting servers is too 1990s. SaltStack provides a middle ground.

It's a bit opinionated, but so is everything else on the internet.
