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.

Initializing (pre-warm) EBS volumes

It used to be the case that all EBS storage was meant to be initialized to avoid the first-time-access penalty, which becomes a noticeable overhead as you start dealing with larger and larger volumes. Nowadays, the situation has improved as new volumes need no pre-warming (ref:; however, one should still consider the added delay to the boot process (if the volume is needed at boot time) against any potential performance gains.

For very large volumes, initialization might be prohibitive, but in any other case, it is certainly worth doing. Or if you run your own database servers on EC2, then you should definitely consider pre-warming volumes regardless of size.

You could use the suggested command-line steps to measure time spent performing this type of optimization (refer to
