Effective DevOps with AWS - Second Edition

Overview of this book

The DevOps movement has transformed the way modern tech companies work. Amazon Web Services (AWS), which has been at the forefront of the cloud computing revolution, has also been a key contributor to the DevOps movement, creating a huge range of managed services that help you implement DevOps principles. Effective DevOps with AWS, Second Edition will help you to understand how the most successful tech start-ups launch and scale their services on AWS, and will teach you how you can do the same. This book explains how to treat infrastructure as code, meaning you can bring resources online and offline 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. Once you have gotten to grips will all this, we'll move on to how to scale your applications to offer maximum performance to users even when traffic spikes, by using the latest technologies, such as containers. In addition to this, you'll get insights into monitoring and alerting, so you can make sure your users have the best experience when using your service. In the concluding chapters, we'll cover inbuilt AWS tools such as CodeDeploy and CloudFormation, which are used by many AWS administrators to perform DevOps. By the end of this book, you'll have learned how to ensure the security of your platform and data, using the latest and most prominent AWS tools.

Chapter 3. Treating Your Infrastructure as Code

In the previous chapter, we familiarized ourselves with AWS. We also created an EC2 instance and deployed a Hello World web application onto it. However, to get there, we had to go through a number of steps to configure the instance and its security groups. Because we did that in a very manual fashion using the command-line interface, the steps that we went through will not be reusable or auditable, as you may recall from the first chapter when implementing DevOps best practices. Two key concepts that you should rely on as often as possible are source control (version control) and automation. In this chapter, we will explore how to apply those principles to our infrastructure.

In a cloud environment, where almost everything is abstracted and served through the intermediary of virtual resources, it is easy to imagine that code can describe the topology of a network and the configuration of a system. To go through that transformation, we will...
