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.

Leveraging Immutable Infrastructure in the Cloud

Among many other benefits of AWS, one that stands out is the ease of provisioning resources in the cloud, dynamically scaling them, and bringing them down again when they’re no longer required. This is a big mental shift from how IT resources were perceived and managed on-premises. Software applications have also evolved during this time and the infrastructure advancements have complemented this unprecedented growth.

If you’ve been in IT for more than a decade, you would agree that every situation around the lack of resources back then was addressed by vertically scaling up the existing servers. Adding more memory, storage, or compute solved most of the problems. Servers would be idle for months and years and get in-place upgrades when applications needed to do more. To make the software applications resilient to hardware failures, companies started looking at other options, such as horizontal scaling, also known as...
