Hands-On Reactive Programming with Python

By: Romain Picard

Overview of this book

Reactive programming is central to many concurrent systems, but it’s famous for its steep learning curve, which makes most developers feel like they're hitting a wall. With this book, you will get to grips with reactive programming by steadily exploring various concepts This hands-on guide gets you started with Reactive Programming (RP) in Python. You will learn abouta the principles and benefits of using RP, which can be leveraged to build powerful concurrent applications. As you progress through the chapters, you will be introduced to the paradigm of Functional and Reactive Programming (FaRP), observables and observers, and concurrency and parallelism. The book will then take you through the implementation of an audio transcoding server and introduce you to a library that helps in the writing of FaRP code. You will understand how to use third-party services and dynamically reconfigure an application. By the end of the book, you will also have learned how to deploy and scale your applications with Docker and Traefik and explore the significant potential behind the reactive streams concept, and you'll have got to grips with a comprehensive set of best practices.

An introduction to S3 storage

The Simple Storage Service (usually named S3) is a storage service provided by Amazon in its Amazon Web Services (AWS) cloud offering. S3 was one of the first services provided by AWS. It was made publicly available in March 2006, and presented as the Amazon in-house storage solution accessible to everybody. S3 is not only very different from a relational database, but also different from a NoSQL database (which also grew in popularity at the same time). S3 is based on the very simple principle of storing a value with an associated key, and retrieving that value via this key. In its simplest definition, it is just a key/value store. There is no notion of searches, transactions, or joins in S3. It looks more like a filesystem than a database. However, it benefits from the usual cloud promises: scalability, availability, redundancy, and easy access...
