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. Toward the end of the book, you will learn some tricks and tips to optimize and secure your AWS environment. By the end of the book, you will have mastered the art of implementing DevOps practices onto AWS.

How many VPCs are you foreseeing having? Would they be linked (VPC peering) or would you be bridging other networks in (VPN)?

The answers to these questions play a role when choosing the CIDR for a VPC. As a general rule it is recommended to avoid common (household router) network addresses such as 192.168.1.0 or 10.0.0.0.

Keep track of and assign different CIDRs if you have more than one VPC, even if you don't have an immediate need to peer them.

Consider a CIDR that will allow for large enough subnets to accommodate potential instance scaling with minimal fragmentation (number of subnets).

Subnets and Availability Zones

Availability Zones (AZs) are how we add resilience to a deployment, so we should have at least two of those. There might...
