Example Concept: Terraform uses HashiCorp Configuration Language (HCL), which is declarative and focuses on describing the desired state of infrastructure. It has a vast ecosystem of providers and modules, making it easy to integrate with many cloud services. Pulumi, on the other hand, allows developers to write infrastructure code using general-purpose programming languages like Python, JavaScript, or Go, providing more flexibility and the ability to use existing programming constructs and libraries. This can be beneficial for teams that prefer using a single language across their stack or need complex logic in their IaC definitions.
