This book will give you a very good understanding of microservices and serverless computing, as well as their benefits and drawbacks compared to existing architectures. You will gain an appreciation for the power of deploying a full serverless stack, not only when you save money in terms of running costs, but also in terms of support maintenance and upgrading. This effectively allows your company to go to market a lot quicker with any new products, and beat your competitors in the process. You will also be able to create, test, and deploy a scalable, serverless microservice where the costs are paid per usage and not as per their up time. In addition, this will allow you to autoscale based on the number of requests, while security is natively built in and supported by AWS. So, now that we know what lies ahead, let's jump right into the book.

If you are a developer with basic knowledge of Python and want to learn how to build, test, deploy, and secure microservices, then this book is for you. No prior knowledge of building microservices is required.

, Serverless Microservice Architectures and Patterns, provides an overview of monolithic and microservice architectures. You will learn about design patterns and principles and how they relate to serverless microservices.

, Creating Your First Serverless Data API , discusses security and its importance. We will discuss IAM roles and get an overview of policies and some of the security concepts and principles involved in securing your serverless microservices, specifically regarding Lambda, API Gateway, and DynamoDB.

, Deploying Your Serverless Stack , shows you how to deploy all that infrastructure using only code and configuration. You will learn about different deployment options.

, Testing Your Serverless Microservice , covers the concept of testing. We will explore many types of testing, from unit tests with mocks, integration testing with Lambda and API Gateway, debugging a Lambda locally, and making a local endpoint available, to load testing.

, Securing Your Microservice, covers important topics on how to make your microservices secure.

Some prior programming knowledge will be helpful.

All the other requirements will be mentioned at the relevant points in the respective chapters.
