In this chapter, we learned how to manage infrastructure efficiently by using code. We first learned about CloudFormation, a service from AWS that lets you create templates for your different services to describe each AWS component used and its configuration. In order to simplify the creation of those templates, we looked at a couple of options, ranging from CloudFormation Designer, a tool with a GUI, to troposphere, a Python library. After that, we looked at configuration management, one of the most well-known aspects of the DevOps philosophy. To illustrate this topic, we looked at Ansible, one of the most popular configuration management solutions. We first looked at the different ways to use Ansible commands and ran simple commands against our infrastructure.

Overview of this book
The DevOps movement has transformed the way modern tech companies work. AWS which has been on the forefront of the Cloud computing revolution has also been a key contributor of this DevOps movement creating a huge range of managed services that help you implement the DevOps principles.
In this book, you’ll see how the most successful tech start-ups launch and scale their services on AWS and how you can too. Written by a lead member of Mediums DevOps team, this book explains how to treat infrastructure as code, meaning you can bring resources online and offline as necessary with the code as easily as you control your software. You will also build a continuous integration and continuous deployment pipeline to keep your app up to date. You’ll find out how to scale your applications to offer maximum performance to users anywhere in the world, even when traffic spikes with the latest technologies, such as containers and serverless computing. You will also take a deep dive into monitoring and alerting to make sure your users have the best experience when using your service.
