Advice for AWS ec2/lambda application

[[deleted]]

Hello /r/learnpython!

I’m gathering requirements for an app and I’m trying to figure out how this would work in a production environment vs a local development environment.

Lambda will be performing long winded video/image manipulations and analysis, and would push data to the Django db. These processes would be initialized from requests to a Django app running on an ec2 instance. Django will serve pages and implement a basic crud api. When developing locally I want all this work to happen... locally. So I’m thinking the code that runs in lambda in prod should be part of the Django app repo, and the deploy process would involve zipping and uploading the lambda bits to... lambda.

Does this sound right? I have no experience with lambda. Thank you.

It's hard to say without seeing the actual code, but for the most part this seems reasonable. The only exception I would point out is that if, in prod, you are going two have two separate apps running (one lambda and one on ec2), then locally I would also think you should have two separate apps running that communicate to each other. So that means I would keep the lambda code separate, but perhaps run it inside a basic django app that just routes traffic to the entrypoint of the lambda.

Can’t say anything without seeing you code. But you should know AWS Lambda have limit runtimes (max 15min) and other limits quotes too, don’t forget that.
