What this book covers

Chapter 1, Breaking the Monolith, shows how to make the transition from monolith to microservices, with the recipes focused on architectural design. You'll learn how to manage some of the initial challenges when you begin to develop features using this new architectural style.

Chapter 2, Edge Services, teaches you how to use open source software to expose your services to the public internet, control routing, extend your service's functionality, and handle a number of common challenges when deploying and scaling microservices.

 Chapter 3, Inter-Service Communication, discusses recipes that will enable you to confidently handle the various kinds of interactions we're bound to require in a microservice architecture.

Chapter 4, Client Patterns, discusses techniques for modeling dependent service calls and aggregating responses from various services to create client-specific APIs. We'll also discuss managing different microservices environments and making RPC consistent with JSON and HTTP, as well as the gRPC and Thrift binary protocols.

Chapter 5, Reliability Patterns, discusses a number of useful reliability patterns that can be used when designing and building microservices to prepare for and reduce the impact of system failures, both expected and unexpected.

Chapter 6, Security, includes recipes that will help you learn a number of good practices to consider when building, deploying, and operating microservices.

Chapter 7, Monitoring and Observability, introduces several tenants of monitoring and observability. We'll demonstrate how to modify our services to emit structured logs. We'll also take a look at metrics, using a number of different systems for collecting, aggregating, and visualizing metrics. 

Chapter 8, Scaling, discusses load testing using different tools. We will also set up auto-scaling groups in AWS, making them scalable on demand. This will be followed by strategies for capacity planning.

Chapter 9, Deploying Microservices, discusses containers, orchestration, and scheduling, and various methods for safely shipping changes to users. The recipes in this chapter should serve as a good starting point, especially if you're accustomed to deploying monoliths on virtual machines or bare metal servers.
