Serverless Deployments of Python APIs

If you are like me, you were starting to get comfortable with the idea of deploying your applications to cloud instances such as EC2s on AWS or droplets on DigitalOcean, when people started to shift away from cloud instances and embrace containers. Maybe now you are getting into containers and Docker, and as is to be expected, the tech world is making a move once again, this time to severless computing. Impossible to ever catch up, right?

In this article I'm going to tell you what a serverless architecture can offer you that the more traditional approaches cannot (and more specifically how it is possible to run your Python web applications without a server!). At the time I'm writing this, AWS has by far the most mature serverless platform, with the Lambda, API Gateway and DynamoDB triad of services at the forefront, so this is the platform I'm going to concentrate on.

Flask Video Streaming Revisited

Flask Video Streaming Server

Almost three years ago I wrote an article on this blog titled Video Streaming with Flask, in which I presented a very modest streaming server that used a Flask generator view function to stream a Motion-JPEG stream to web browsers. My intention with that article was to show a simple, yet practical use of streaming responses, a not very well known feature in Flask.

That article is extremely popular, but not because it teaches how to implement streaming responses, but because a lot of people want to implement streaming video servers. Unfortunately, my focus when I wrote the article was not on creating a robust video server, so I frequently get questions and requests for advice from those who want to use the video server for a real application and quickly find its limitations. So today I'm going to revisit my streaming video server and describe a few improvements I've made to it.
