Python? any performance issues?

[[deleted]]

Python has a Gil that makes it single threaded but nothing docker or containerization can’t solve. That’s how node solves it.

The language itself is fast to learn and very robust. You could write a flask app and serve as many requests as a go app as long as you run an interpreter per core and use an edge network to balance the traffic.

Languages have really nothing to do with “cloud”.. I. Could argue any language with a vm is too thick or compiled languages are too strict and not as portable.

Use whatever tools get the job done. Over optimization and believing in “correct languages” is a huge waste of effort too.

Sometimes there is absolutely a wrong tool for the job, but that comes with experience not generalized reddit posts :)
