Hands-On Microservices with Rust

By: Denis Kolodin

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.

Composing a microservice set

Docker Compose is an awesome tool for deploying and running a set of microservices that can be connected each other. It helps you to define a multi-container application with configuration parameters in a human-readable YAML file. You are not limited to local deployment only and you can deploy it on a remote server on which the Docker daemon is also running.

In this section of the chapter, we will pack all our microservices with a database into a single application. You will learn how to set variables for Rust frameworks and loggers, how to connect microservices, how to define the order to start containers, how to read the logs of a running application, and how to use different configurations for testing and production.
