Hands-On Swift 5 Microservices Development

Overview of this book

The capabilities of the Swift programming language are extended to server-side development using popular frameworks such as Vapor. This enables Swift programmers to implement the microservices approach to design scalable and easy-to-maintain architecture for iOS, macOS, iPadOS, and watchOS applications. This book is a complete guide to building microservices for iOS applications. You’ll start by examining Swift and Vapor as backend technologies and compare them to their alternatives. The book then covers the concept of microservices to help you get started with developing your first microservice. Throughout this book, you’ll work on a case study of writing an e-commerce backend as a microservice application. You’ll understand each microservice as it is broken down into details and written out as code throughout the book. You’ll also become familiar with various aspects of server-side development such as scalability, database options, and information flow for microservices that are unwrapped in the process. As you advance, you’ll get to grips with microservices testing and see how it is different from testing a monolith application. Along the way, you’ll explore tools such as Docker, Postman, and Amazon Web Services. By the end of the book, you’ll be able to build a ready-to-deploy application that can be used as a base for future applications.

Setting up a microservice environment

So far, you have been running your microservices locally on your computer. In this section, we'll talk about what a microservice environment should look like in ideal terms. A microservice environment consists of multiple servers that are running the microservices. Each of these servers can be treated independently since they may be physically separated. We'll start by looking at a single-server setup and progress toward a multi-server setup.

We'll explore the following topics:

  • Starting with a simple service: We'll get a service up and running with just one server.
  • Managing databases and microservices: We'll offload extra services to increase the performance of our application.
  • Using the power of a load balancer: We'll bring multiple services together.
  • Final setup: Most production apps have a similar setup to...
