Lecture 02 – TERRAFORM AND INSTALLATION

1.- Declarative Configuration: Infrastructure is described using a simple, human-readable language called HashiCorp Configuration Language (HCL) or JSON. You specify the desired state of your infrastructure, and Terraform takes care of managing the resources to achieve that state.

2.- Resource Management: Terraform supports a wide range of cloud providers, including AWS, Azure, Google Cloud Platform (GCP), and many others. It also supports various resource types such as virtual machines, networks, storage, databases, security groups, and more.

3.- Dependency Management: Terraform automatically determines the dependencies between resources and provisions them in the correct order. This ensures that resources are created or modified in a way that satisfies their interdependencies.

4.- State Management: Terraform maintains the state of your infrastructure in a state file. This file keeps track of the resources that have been created or modified, allowing Terraform to perform incremental changes on subsequent runs.

5.- Execution Plans: Before making any changes to your infrastructure, Terraform generates an execution plan that shows what actions will be taken. This allows you to review and validate changes before applying them.

6.- Idempotent Operations: Terraform ensures that the desired state of the infrastructure is achieved, regardless of how many times the configuration is applied. It only makes changes if there are differences between the current state and the desired state.
