Consistent pre-tested security configurations are applied to all environments. The initial era of web hosting and IT services was not easy for system administration.
Configuring a new environment on the server side was a long and laborious process that required physical racking of servers, manual setup of network connections, installation of the operating system, and configuration of each parameter by hand.
Even with the introduction of cloud computing, manual configuration via web consoles took a lot of time. This is how the concept of Infrastructure as Code changes everything for modern IT operations.
Also known as IaC, Infrastructure as Code refers to an IT management approach which utilizes machine-readable definition files in order to provision and manage the computing infrastructure instead of using manual configuration tools and manual changes to physical hardware.
Rather than working with manual administrative dashboards, developers create code configurations to define the desired state of their servers, networks, and storage elements.
This method regards your infrastructure just as a piece of code that is easily version-controlled, shareable, testable, and deployable with a simple command.
There are basically two ways of approaching infrastructure automation when building one:
When using a declarative approach, you need to specify the final state of the required infrastructure that should be created, and the IaC tool automatically works out how to do it. You only need to tell the tool that you want three web servers and a database, and it works out the process of creating them for you.
With an imperative approach, the developers write a script specifying all the steps that need to be followed by the system when creating the infrastructure.
The usage of cloud automation by means of IaC provides various benefits:
Cloud automation lets developers set up a ready-to-go production environment in a matter of minutes and ensures that all deployments will be uniform without any chance of errors, while accelerating feature delivery timelines and eliminating costly manual setup delays entirely.
Infrastructure files saved in Git will give you a history of changes, which will help you track them or return to the previous version if something goes wrong, providing total transparency and auditability across your entire software engineering team.
Servers are constantly tweaked manually by operators, so configuration drift is likely to occur. But IaC makes sure that your configuration is consistent all the time by continuously enforcing standardized baseline templates across development, staging, and production servers.
Developers can automatically tear down unused testing environments and avoid paying cloud services for their maintenance, significantly reducing monthly cloud infrastructure billings and optimizing overall engineering budget allocation.
There are a number of popular tools available that assist organizations in controlling their cloud resources either in a declarative manner or an imperative manner.
An open-source tool that employs declarative configuration files for seamless management and provisioning of infrastructure in a multi-cloud environment, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
A human-readable automation solution that is built to manage configurations, application deployments, and orchestration processes.
Vendor-driven cloud solutions that are specifically built to declaratively create and manage cloud resources within their respective proprietary platforms.
By using these tools, there is no need for manual configurations, as they help minimize errors and maintain consistency across development, staging, and production environments.
Whether it’s hybrid clouds or a single cloud, with IaC tools, software operation processes can be scaled efficiently.

It is clear from the description of the concept of Infrastructure as Code that it is a very important element among the fundamental elements of DevOps and IT management.
It is possible to achieve quick deployment of the system, cut down operational expenses, and avoid any mistakes in the configuration process due to the fact that all hardware and cloud configurations turn into software code.
Ans: Automated management and provisioning of IT infrastructure through code scripts.
Ans: Because of multi-cloud, vendor agnostic declarative infrastructure provisioning.
Ans: Consistent pre-tested security configurations are applied to all environments.
