IaC, for short, is nothing more than the application of best practices from software development applied to infrastructure. It consists of repeatable and consistent routines for provisioning systems and their configuration. Changes to such systems are made using code definitions and then applied to the infrastructure by unattended processes.
Using software development practices opens the door to continuous integration (CI) and continuous delivery/deployment (CD). This also allows the application of version control systems and deployment orchestration to manage infrastructure.
The major goals of Infrastructure as Code:
- IT stops being a blocker to change, instead it embraces and supports it.
- By automating infrastructure change, IT consultants spend their time in valuable things instead of repetitive tasks.
- Dev Teams are enabled to define and provision their own resources without needing the direct involvement of technical teams.
- Changes in the infrastructure are routine, and improvements are continuous.
- Solutions are proven by implementing and testing rather than discussed on long and tedious meetings.
With the adoption of Cloud native solutions, IaC has become even a greater ally to companies. The ability to create and destroy servers and applications by using code accelerates business time to market and allows teams to focus on better end user experience.
It should be possible to rebuild any resource or service in the infrastructure without effort and in a reliable way. This removes much of the risk and fear of making changes. If by any reason a failure does occur, it can be handled quickly.
Not too long ago, servers were treated as pets. We gave them names that were thought with much care. Today we should treat servers as cattle.
Today, infrastructure should be made to be disposable and replaceable. It should be designed with the knowledge that it will be always changing and for that reason, we should be able to destroy it or recreate it easily.
Applications should continue to run smoothly while servers are changed, resized, destroyed or recreated.
The ability to handle changes elegantly makes it easier to apply improvements and fixes on the infrastructure. It also allows services to be more tolerant to failure which becomes especially important when working on large scale cloud infrastructure that needs to scale in or out on demand in a matter of minutes.
