Overview of this book

Knowing how to adopt DevOps in your organization is becoming an increasingly important skill for developers, whether you work for a start-up, an SMB, or an enterprise. This book will help you to drastically reduce the amount of time spent on development and increase the reliability of your software deployments on AWS using popular DevOps methods of automation. To start, you will get familiar with the concept of IaC and will learn to design, deploy, and maintain AWS infrastructure. Further on, you’ll see how to design and deploy a Continuous Integration platform on AWS using either open source or AWS provided tools/services. Following on from the delivery part of the process, you will learn how to deploy a newly created, tested, and verified artefact to the AWS infrastructure without manual intervention. You will then find out what to consider in order to make the implementation of Configuration Management easier and more effective.

The object storage layer

In the effort of achieving effortless scalability, we must put emphasis on building stateless applications where possible. Not keeping state on our application nodes would mean storing any valuable data away from them. A classic example is WordPress, where user uploads are usually kept locally, making it difficult to scale such a setup horizontally.

While it is possible to have a shared file system across your EC2 instances using Elastic File System (EFS), for reliability and scalability we are much better off using an object storage solution such as AWS S3.

It is fair to say that accessing S3 objects is not as trivial as working with an EFS volume, however the AWS tools and SDKs lower the barrier considerably. For easy experimenting, you could start with the S3 CLI. Eventually you would want to build S3 capabilities into your application using one of the following:
