Need for Infrastructure Provisioning

• In CI/CD pipelines, we need to create various test environments according to organizational QA policy.

• To create test environments, we might also need to create virtual infrastructure on the cloud / Hypervisor (VMWare, Hyper-V).

• To automate this infrastructure creation/updation we need some kind of a tool and these tools are called as Infra Provisioning Tools

• Depending on the infrastructure used in the organization we will have different tools which can help us in automating infrastructure creation

• To solve this problem an organization called as Hashicorp has came up with a tool called as Terraform which can work with multiple infra providers

• Procedural vs Declarative

• Using Terraform we would use declarative approach to specify what are our infrastructure needs => Infrastructure as Code (IaC)

• Workflow:

• Terraform is Cloud-agnostic because deploy to any cloud or virtual infra provider

• Terraform integrates with different clouds through Terrraform providers
