All About Terraform


Before starting to learn what Terraform is. We need to understand what it is Infra As Code.
Infrastructure as Code (IaC) is a way of managing and setting up your IT infrastructure using code, rather than manually configuring individual systems.
  • With IaC, you write code to describe the desired state of your infrastructure, such as the number of servers you need and how they should be connected. 
  • Tools like Terraform can then automatically execute this code to create and manage your infrastructure for you. 
  • The benefits of using IaC include better consistency and reliability and easier collaboration and management since all of your infrastructure is defined and managed in a single place.
  • Additionally, since IaC is code, you can version control it, making it easier to track changes and roll back to previous configurations if needed

So What is Terraform?

Terraform

Terraform is a software tool that helps you manage and set up your infrastructure, such as the computers and servers you use for your business or website.
With Terraform, you can define how you want your infrastructure to look, and the tool will automatically create and update it for you. This makes it easier for you to manage your infrastructure and keep it running smoothly, without manually making changes or keeping track of complex details.

Terraform can also work with different cloud providers, so you can manage your infrastructure from one place, making it a versatile and powerful tool for anyone who needs to run and maintain their own infrastructure.

What is DevOps? Hey Folks, We live in an era where machines and their Intelengency rule over Human Efforts and make our day-to-day tasks easy. Where we are now completely dependent upon machines for any small or big task. So all the backend processes used in the working of any Machines, Applications, or Websites need to be real quick and fast. For example, you prepared an application or a machine but it's the hardware or just a view. What makes it run is its software (Soul of any Machines, Application, or Website). Now, what is Software? Software is nothing but a collection of data or instructions that tell the Application (Computer, Machines, Hardware, Website, etc...) how to work. Software Life Cycle..! Okay so now you know what is software, but every software is first needed to be developed according to the requirement, and then it goes for testing if testing is failed it again goes for the redevelopment once the testing process is tested successfully then i
