Overview of this book

Microservice architecture is sweeping the world as the de facto pattern for building web-based applications. Rust is a language particularly well-suited for building microservices. It is a new system programming language that offers a practical and safe alternative to C. This book describes web development using the Rust programming language and will get you up and running with modern web frameworks and crates with examples of RESTful microservices creation. You will deep dive into Reactive programming, and asynchronous programming, and split your web application into a set of concurrent actors. The book provides several HTTP-handling examples with manageable memory allocations. You will walk through stateless high-performance microservices, which are ideally suitable for computation or caching tasks, and look at stateful microservices, which are filled with persistent data and database interactions. As we move along, you will learn how to use Rust macros to describe business or protocol entities of our application and compile them into native structs, which will be performed at full speed with the help of the server's CPU. Finally, you will be taken through examples of how to test and debug microservices and pack them into a tiny monolithic binary or put them into a container and deploy them to modern cloud platforms such as AWS.

Packing Servers to Containers

Microservices created with Rust are pretty simple to deploy: it's sufficient to build a binary for your server, upload that binary to your server, and start it. But that's not a flexible approach for real applications. Firstly, your microservice may need files, templates, and configuration. On the other hand, you may want to use servers with different operating systems. In that case, you would have to build a binary for every system. To reduce the amount of issues with deployment, modern microservices are packed to containers and use virtualization to launch. Virtualization helps to simplify the deployment of a set of microservices. Also, it can help to scale a microservice, because to run an extra instance of a microservice you should only start another copy of the container.
