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.

Summary

This chapter covered good practices for creating reactive microservices architecture. We started our learning from basic concepts: what a reactive approach is, how to implement it, and how remote procedure calls helps to implement message-driven architecture. Also, we discussed existing RPC frameworks and crates that you can use simply with Rust.

To demonstrate how reactive applications work, we created two examples of microservices that use RPC methods to interact with each other. We created an application that uses a ring of running microservices that send requests to each other in a loop till every instance is informed about an event.

We also created an example that uses the JSON-RPC protocol for instance interaction and used the jsonrpc-http-server crate for the server side and the JSON-RPC crate for the client side.

After that, we created an example that uses...
