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.

Integrating AWS, Terraform, and Ansible

In the previous sections, we looked at how to provision a vanilla instance using Terraform. We then learnt how to provision a vanilla EC2 instance and execute post builds using the Terraform remote-exec provisioner. Now, we'll look at how Terraform can be integrated with Ansible to perform configuration management tasks. We will consider two different scenarios. In scenario one, we will provision an EC2 instance and run Ansible using push mode, which is the primary way that we can use Ansible to perform automation. In scenario two, we will provision an EC2 instance and run Ansible in pull mode using the ansible pull approach.

Terraform with Ansible using a push-based approach

Go into the EffectiveDevOpsTerraform repository and create a directory called thirdproject:

$ mkdir thirdproject
$ cd thirdproject

In this example, we will use the recommended practices to create Terraform templates. We will remove our AWS access_key and our AWS secret_key from our...
