Now let’s dive into Terraform.
Greetings hoodies! In our last article, we learned about CircleCI. Continuing the DevOps series we are going to learn to terraform in this article. Let's get into it.
What is IaC?
Before we get into terraform let's learn a bit about IaC. Infrastructure as a Code (IaC) is the model Terraform uses. As the name suggests you create an infrastructure with code. In the cloud articles, we learned to deploy services from the web console. But that’s ok for a small amount of resources and small configurations.
When we want to deploy resources for infrastructure businesses we need to do this faster and better. This is where IaC shines, you can create a config file similar to YAML files, and include all your resources and configuration there. Create the code and let the IaC tool (eg terraform, CloudFormation) do the deployment.
What is Terraform?
Terraform is an open-source infrastructure as code (IaC) technology created by HashiCorp. It enables you to define and manage your infrastructure resources in declarative mode. Terraform allows you to write configuration files often in HashiCorp Configuration Language (HCL), that describe the desired state of your infrastructure. Terraform then uses these configuration files to provision and manage resources across many cloud platforms, including Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Terraform is primarily designed for infrastructure provisioning and orchestration, allowing you to create, edit, and destroy resources with speed and ease.
Terraform Architecture
It is advisable to learn the basics of terraform architecture but you can skip it to practical if you prefer. The Terraform architecture consists of several components that work together to provision and manage infrastructure resources.
