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.

EIP versus public IP


A few points about the two types, in case you have not used these much.

Public IPs:

  • You choose whether an instance should have a public IP at the time you are launching it

  • The address will persist across reboots but not a stop/start

  • These come at no extra cost

Elastic IPs:

  • You can associate/disassociate an EIP with an instance at any time after it has been launched

  • An EIP remains associated across reboots or start/stop operations

  • EIPs incur cost (when kept unused)

  • EIPs can be migrated between EC2 instances

In light of the IPv4 deficit we are facing today, AWS is cleverly trying to incentivize sensible provisioning by charging for any dormant EIP resources.

Tip

Be a gentleman/lady and release your IPs when you are done with them.
