Implementing DevOps on AWS

By: Vaselin Kantsev

Overview of this book

Knowing how to adopt DevOps in your organization is becoming an increasingly important skill for developers, whether you work for a start-up, an SMB, or an enterprise. This book will help you to drastically reduce the amount of time spent on development and increase the reliability of your software deployments on AWS using popular DevOps methods of automation. To start, you will get familiar with the concept of IaC and will learn to design, deploy, and maintain AWS infrastructure. Further on, you’ll see how to design and deploy a Continuous Integration platform on AWS using either open source or AWS provided tools/services. Following on from the delivery part of the process, you will learn how to deploy a newly created, tested, and verified artefact to the AWS infrastructure without manual intervention. You will then find out what to consider in order to make the implementation of Configuration Management easier and more effective. Toward the end of the book, you will learn some tricks and tips to optimize and secure your AWS environment. By the end of the book, you will have mastered the art of implementing DevOps practices onto AWS.

IaC using CloudFormation


CloudFormation is an AWS service for deploying infrastructure as code. As before, we are going to describe our infrastructure via templates containing parameters (variables), resources, and outputs.

CloudFormation calls each deployed template a Stack. Creating, listing, updating, and deleting stacks is possible via the AWS Console, CLI, or API. In a small setup, you would probably deploy each of your stacks individually, but as your architecture becomes more complex, you can start nesting stacks. You would have a top-level or a parent stack (template) that invokes a number of sub-stacks. Nested stacks allow you to pass variables between them and, of course, save you the time of having to deploy each one individually.

Configuration

CloudFormation provides a GUI via the AWS Console; we however, are going to focus on the AWS CLI since it is most suitable for automating tasks in the future.
