Overview of this book

AWS CodeDeploy, AWS CodeBuild, and CodePipeline are scalable services offered by AWS that automate an application's build and deployment pipeline. In order to deliver tremendous speed and agility, every organization is moving toward automating their entire application pipeline. This book will cover all the AWS services required to automate your deployment to your instances. You'll begin by setting up and using one of the AWS services for automation –CodeCommit. Next, you'll learn how to build a sample Maven and NodeJS application using CodeBuild. After you've built the application, you'll see how to use CodeDeploy to deploy the application in EC2/Auto Scaling. You'll also build a highly scalable and fault tolerant Continuous Integration (CI)/Continuous Deployment (CD) pipeline using some easy-to-follow recipes. Following this, you'll achieve CI/CD for a microservice application and reduce the risk within your software development life cycle globally. You'll also learn to set up an infrastructure using CloudFormation templates and Ansible, and see how to automate AWS resources using AWS Lambda. Finally, you'll learn to automate instances in AWS and automate the deployment lifecycle of applications. By the end of this book, you'll be able to minimize application downtime and implement CI/CD, gaining total control over your software development lifecycle.

Understanding microservices and their deployment

Microservices is basically the variant of service-oriented architecture (SOA) that breaks the entire application into service components. These services will serve the request by communicating with each other through service discovery or Remote Method Invocation (RMI):

Difference between monolithic and microservice architecture

The characteristics of microservice-based applications are as follows:

  • Service enabled, independently running components
  • Each service has its own functionalities
  • Components using simple communication channels such as service discovery, REST protocol, or messaging protocol
  • Decentralized stack, that is, every component can have its own development stack and way of deployment
  • Decentralized Data Storage and Management, where each business logic service has its own databases, as you can see in the preceding...
