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.

Creating our Terraform repository

We have now looked at two modes for creating AWS EC2 instances: using AWS Management Console and using AWS CLI. These can be automated using the AWS cloud native service called CloudFormation template, as we saw in Chapter 3, Treating Your Infrastructure as Code. This is only applicable for use with the AWS cloud. In this chapter, we will achieve the same results of provisioning AWS instances using Terraform. Refer to https://www.terraform.io/intro/vs/cloudformation.html to understand the differences between Terraform and CloudFormation.

Let's create a dedicated repository in our GitHub account and start our journey with Terraform. Once you've logged in to GitHub, create a new repository for the Terraform templates by following the steps below:
