Infrastructure as a Code

In the previous chapter, we looked at the basics of AWS Lambda, starting with creating an AWS account to develop our first micro function. However, our deployment process was pretty manual and obviously not production-ready. Based on the principle of "if you repeat a task three times, it's time to automate", it is time to automate this process in order to build a first-class deployment process that will automate and facilitate our workflow.

If you have ever used AWS Lambda in other languages, you might have heard about some frameworks such as Serverless, Apex, or Kappa. These are valuable open source tools with great features, and they used to be very essential for AWS Lambda development with features such as packaging the code, creation of API Gateway endpoints, and so on. If you are authoring Lambda functions in JavaScript or Python, it...

Key benefits

Design a real-world serverless application from scratch

Learn about AWS Lambda function and how to use Lambda functions to glue other AWS Services

Use the Java programming language and well-known design patterns. Although Java is used for the examples in this book, the concept is applicable across all languages

Learn to migrate your JAX-RS application to AWS Lambda and API Gateway

Description

Over the past years, all kind of companies from start-ups to giant enterprises started their move to public cloud providers in order to save their costs and reduce the operation effort needed to keep their shops open. Now it is even possible to craft a complex software system consisting of many independent micro-functions that will run only when they are needed without needing to maintain individual servers. The focus of this book is to design serverless architectures, and weigh the advantages and disadvantages of this approach, along with decision factors to consider. You will learn how to design a serverless application, get to know that key points of services that serverless applications are based on, and known issues and solutions. The book addresses key challenges such as how to slice out the core functionality of the software to be distributed in different cloud services and cloud functions. It covers basic and advanced usage of these services, testing and securing the serverless software, automating deployment, and more. By the end of the book, you will be equipped with knowledge of new tools and techniques to keep up with this evolution in the IT industry.
