What is meant by Infrastructure as Code (IaC)?

In an AWS DevOps interview, this is one of the most often asked topics. IaC is a popular DevOps approach in which code and software development techniques aid in the management of the whole infrastructure, including anything from continuous integration to version control. The cloud API paradigm makes it much easier for developers to programmatically interact with the whole infrastructure.

Infrastructure as Code (IaC) is the foundation the board (systems, virtual machines, load balancers, and association geography) in an illustrative model, utilizing a similar form control that the DevOps group utilizes for code. source. Like the rule that a similar source code produces a similar twofold, an IaC model creates a similar situation each time it is applied. IaC is a key DevOps practice and is utilized related to consistent conveyance.

Infrastructure as Code has evolved to address the issue of environmental drift in the launch pipeline. Without IaC, teams must maintain the configuration of individual deployment environments. Over time, each environment turns into a snowflake, that is, a unique configuration that cannot be reproduced automatically. Inconsistency between environments causes problems during deployments. With snowflakes, managing, and maintaining your infrastructure involves manual processes that are difficult to follow and have contributed to errors.
