Terraform & Infrastructure as Code explained for non-developers

Alistair Heys

Today, we're going to explore the world of IaC and Terraform. Don't worry, we'll keep it simple and free from any unnecessary flair. Let's dive right in!

IaC, short for Infrastructure as Code, is a concept that involves using code to define and manage your technology infrastructure. Instead of manually setting up and configuring everything, you write code that describes the desired state of your infrastructure. It's like having a digital blueprint for your tech setup.

Now, let's talk about Terraform. Terraform is a powerful tool that works hand-in-hand with IaC. It helps you bring that code to life by creating and managing your infrastructure. Whether you need virtual servers, networks, or databases, Terraform has got you covered. It acts as a mediator between your code and various cloud providers like Amazon Web Services, Microsoft Azure, or Google Cloud.

With Terraform, you can specify what components you want in your infrastructure. You write a simple configuration code that tells Terraform what resources you need. For example, if you want ten virtual servers, you write a code that says, "Hey, Terraform, create ten virtual servers!" Then, Terraform communicates with the cloud provider and makes it happen.

One of the great things about Terraform is its flexibility. If you later decide you need more servers or want to make changes to your infrastructure, you can simply update the code. Terraform will apply the necessary modifications while ensuring your infrastructure stays consistent with the desired state.

In summary, IaC and Terraform are a dynamic duo for managing technology infrastructure. IaC allows you to define your infrastructure using code, while Terraform brings that code to life. Together, they simplify the process of creating and managing infrastructure, providing flexibility and automation.

The next time you come across discussions about IaC and Terraform, you'll know they relate to streamlining infrastructure management in the world of technology. Now armed with this knowledge, go forth and embrace the power of IaC and Terraform in your tech endeavours!

Note: While this blog references Terraform, everything mentioned in here also applies to OpenTofu. New to OpenTofu? It is a fork of Terraform 1.5.7 as a result of the license change from MPL to BUSL by HashiCorp. OpenTofu is an open-source alternative to Terraform that is governed by the Linux Foundation. All features available in Terraform 1.5.7 or earlier are also available in OpenTofu. Find out the history of OpenTofu here.
