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 4. Infrastructure as Code with Terraform

In Chapter 3, Treating Your Infrastructure as Code, we familiarized ourselves with AWS CloudFormation and Ansible. We created a CloudFormation template to create an EC2 environment and deployed a HelloWorld web application on it. Taking a step further in the world of automation, we then introduced the Ansible configuration management tool. We learnt about how Ansible takes care of application deployment and orchestration so that CloudFormation templates remain neat and confined until provisioning. This approach is well accepted by the tech giants as far as the AWS cloud is concerned, but when we talk about heterogeneous environments where we have multiple cloud platforms such as AWS, Azure, Google cloud, OpenStack, and VMware then CloudFormation service, as it is a AWS-native service, is not applicable.

Hence, we need an alternative solution that will not only help us to provision compute services but also other cloud native services without...
