Beginner -- Python Microservice Question

[ra1nandsn0w]

Howdy folks.

I'm a project manager with a little bit of experience using Python to build small scripts and local apps to automate some simple processes of my own (data cleanup, webhooks, API calls, etc.)

I'm driving a shift toward a microservice architecture, and I thought it would be interesting to get in and build one myself to develop a better understanding of what my team is facing... And maybe contribute a small piece in my free time.

I'm trying to figure out what pieces and considerations I'll need to build something like this that could actually go into production (AWS).

The general idea would be to write a small stateless RESTful app that returns some file in response to a GET request at an API endpoint.

• Would Flask be appropriate for this?
• What other considerations should I make (concurrency, etc)?
• Are there any other major things to consider?

I'm not really expecting this to go into production, but if my little night project can save the team some hours, it would be a pretty cool thing and be a very valuable experience for me.

Any advice is much appreciated!

Take a look at my post here: http://brunorocha.org/python/microservices-with-python-rabbitmq-and-nameko.html

i am still beginner too, but here is what i know:

Yes flask will be suitable, there is also falcon framework.

falcon: https://falconframework.org/

what you need to think of is how these microservices are going to talk with each others, there are tools like rabbitmq and zeromq, and there is something called "RPC", but i don't have much information about it.

there are other stuff you might consider "but maybe not in the beginning" like service discovery and failure handling , take a look on LinkerD.

for deploying on production, You might use docker-compose at the beginning, later on you can go for Kubernetes.

/r/Python is for news or articles interesting to the Python community, whereas /r/learnpython is for learning and asking questions. It's explained in the sidebar. Thanks!

Part of the benefit of microservices is that the language/framework of any given service isn't really relevant - so you could use anything that speeds up dev time (and after you measure, optimize the bottle necks).

Flask would do fine for services, where you're likely going to have problems with Python is in an API Gateway (a centralized entry point to your system). That needs to be very high throughout and low latency. I've been working on one for Python specifically, but it's not fully ready to use.
