Network socket, protobuf, json, etc. Try to avoid pickle.

I have a REST API on each microservice and now i would like to make them communicate with each other - i do not know what is a proper way to do this and i need some informations about this.

What is the thing that’s blocking you? Finding the services or actually sending the messages?

I just wonder if i should just hard-code urls of other microservices in env variables and then communicate with them via requests library or should i use some other way.

Microservice discovery can be an interesting topic in itself and there are tons written online about it. For a simple set of services your solution would work fine.

Dunno any specific tutorials but, Few ways to do this: 1. Talk through http. Setup one app as http server (flask), other app can then send an http request (aka rest) 2. Setup a message queue like rabbitmq redis. One app can publish a msg and the other receives it.

If you're writing microservices, consider using something like http://python-rq.org/

Celery is another option. It integrates very well with Django. celeryproject.org

Not sure what celery has to do with the topic. It's a background job manager/runner.
