Terraform Providers

Terraform Providers are like Plugins, every provider has its own documentation describing its own resources and usage. The Terraform Registry is the main home for all provider documentation. There are almost 948 Terraform Providers out of which few are AWS, GCP, AZURE, KUBERNETES, OCI, and ALIBABA.
