Managing IT infrastructure has always been a complex job. In a traditional setup, it fell to system administrators to manually configure and manage the software as well as hardware to get the applications up and running. Even though cumbersome, this approach worked just fine when the quantum of infrastructure that needed to be managed was minimal.
However, as the scale of infrastructure continues to expand, managing infrastructure has come down to handling several smaller instances at the same time, rather than a few large ones. The cyclic nature of modern-day infrastructure has made it imperative to transform the way infrastructure is designed, developed, configured, managed, and maintained. That’s where Infrastructure as Code (IaC) comes in.
Let’s take a closer look at what Infrastructure as Code is all about and how it can be leveraged.
