AWS DevOps Simplified

Overview of this book

DevOps and AWS are the two key enablers for the success of any modern software-run business. DevOps accelerates software delivery, while AWS offers a plethora of services, allowing developers to prioritize business outcomes without worrying about undifferentiated heavy lifting. This book focuses on the synergy between them, equipping you with strong foundations, hands-on examples, and a strategy to accelerate your DevOps journey on AWS. AWS DevOps Simplified is a practical guide that starts with an introduction to AWS DevOps offerings and aids you in choosing a cloud service that fits your company's operating model. Following this, it provides hands-on tutorials on the GitOps approach to software delivery, covering immutable infrastructure and pipelines, using tools such as Packer, CDK, and CodeBuild/CodeDeploy. Additionally, it provides you with a deep understanding of AWS container services and how to implement observability and DevSecOps best practices to build and operate your multi-account, multi-Region AWS environments. By the end of this book, you’ll be equipped with solutions and ready-to-deploy code samples that address common DevOps challenges faced by enterprises hosting workloads in the cloud.

Using CodeDeploy to orchestrate deployment workflows in compute environments

Software deployments could mean different things for different technology stacks. For Python-based applications, it could mean placing the scripts at a specific location, and for Java web apps, it could mean deploying WAR (web application archive) files on Tomcat. Whatever the requirement, CodeDeploy can help you deploy different compute environments. You can manage your deployments on servers (EC2/on-premises), Elastic Container Service (ECS), or even Lambda’s serverless platform.

Like CodeBuild, CodeDeploy depends on a manifest file, known as appspec.yml (which can also be JSON formatted). This file contains all the steps CodeDeploy needs to manage your application deployments. On EC2 instances or on-premises servers, this task is delegated to an agent that is already running alongside your application. With ECS and Lambda, the service directly speaks to the respective control plane to roll out...
