Overview of this book

<p>Nowadays, it has become extremely important for programmers to understand the link between the software and the parallel nature of their hardware so that their programs run efficiently on computer architectures. Applications based on parallel programming are fast, robust, and easily scalable. </p><p> </p><p>This updated edition features cutting-edge techniques for building effective concurrent applications in Python 3.7. The book introduces parallel programming architectures and covers the fundamental recipes for thread-based and process-based parallelism. You'll learn about mutex, semaphores, locks, queues exploiting the threading, and multiprocessing modules, all of which are basic tools to build parallel applications. Recipes on MPI programming will help you to synchronize processes using the fundamental message passing techniques with mpi4py. Furthermore, you'll get to grips with asynchronous programming and how to use the power of the GPU with PyCUDA and PyOpenCL frameworks. Finally, you'll explore how to design distributed computing systems with Celery and architect Python apps on the cloud using PythonAnywhere, Docker, and serverless applications. </p><p> </p><p>By the end of this book, you will be confident in building concurrent and high-performing applications in Python.</p>

Cloud Computing

Cloud computing is the distribution of computing services, such as servers, storage resources, databases, networks, software, analysis, and intelligence, via the internet (the cloud). The purpose of this chapter is to provide an overview of the main cloud computing technologies in relation to the Python programming language.

First, we will describe the PythonAnywhere platform, with which we will deploy Python applications on the cloud. In the context of cloud computing, two emerging technologies will be identified: containers and serverless technologies.

Containers represent the new approach to the virtualization of resources, and the serverless technologies represent a step forward in the field of cloud services because they can speed up the release of applications.

In fact, you do not have to worry about the provisioning, the servers...
