Rust Web Development with Rocket

By: Karuna Murti

Overview of this book

Looking for a fast, powerful, and intuitive framework to build web applications? This Rust book will help you kickstart your web development journey and take your Rust programming skills to the next level as you uncover the power of Rocket - a fast, flexible, and fun framework powered by Rust. Rust Web Development with Rocket wastes no time in getting you up to speed with what Rust is and how to use it. You’ll discover what makes it so productive and reliable, eventually mastering all of the concepts you need to play with the Rocket framework while developing a wide set of web development skills. Throughout this book, you'll be able to walk through a hands-on project, covering everything that goes into making advanced web applications, and get to grips with the ins and outs of Rocket development, including error handling, Rust vectors, and wrappers. You'll also learn how to use synchronous and asynchronous programming to improve application performance and make processing user content easy. By the end of the book, you'll have answers to all your questions about creating a web application using the Rust language and the Rocket web framework.

Scaling the Rocket application

After developing the Rocket application and deploying it to a production environment, the application might need to be scaled up due to increasing usage. There are a couple of ways to scale the web application, and they can be categorized into two categories: vertical scaling and horizontal scaling.

Vertical scaling means increasing the resources for a single node. For example, we replace the CPU of the computer that runs the Rocket application with a CPU with higher speed. Another example of vertical scaling is increasing the amount of RAM in the computer that runs the Rocket application.

Horizontal scaling is scaling the application by adding more nodes or more computers to handle the workload. An example of horizontal scaling is running two servers and setting up a Rocket web server on each server.

Suppose we have the following system:
