Python, in all of its greatness, is often dismissed when needing to write performant and distributed applications. It’s considered to be slow and not suited for the task. In this course, you will find that with the right implementation of Python, you can write applications that scale horizontally, perform well, and are distributed. 

To kick things off, you’ll learn about CPU scaling, concurrency, and event loops, all of which are crucial for implementing a distributed system. After that, you’ll move on to queue-based distribution, lock management, and group memberships, which are fundamental concepts for maintaining availability and consistency in distributed applications.

In the last half, you’ll learn how to build a REST API, how to deploy your app to a PaaS, and how to optimize your application's performance.

By the end of this course, you’ll be more productive with Python, you’ll be able to write faster applications that are distributed, and you’ll have a great new skill that is highly coveted.

The Hacker's Guide to Scaling Python

As we have just seen, there is a long list of hosting platforms that you can use and
leverage to deploy your application. This list of cloud platforms is not exhaustive. There are a lot more of them out there. They all have different offerings, while the foundation is usually common: running Python code.

Many of those platforms include more than just running your Python code: database access, message queues, and object storage. These might be necessary building blocks of your application. Most of those services are scalable by design, and the performance of those components is the responsibility of the provider, which is both an advantage and a disadvantage; it is up to you to decide. However, studying those services, what they provide and how they do it, can teach you a thing or two about scalability and the trade-offs you might have to choose.
