In this article, we discuss the use of providers in Terraform and provide examples on how to use the provider for Amazon Web Services (AWS). A provider is a plugin that enables interaction with an API, such as Cloud providers like AWS. The AWS provider is used to manage and deploy resources and infrastructure to AWS after proper configuration with credentials. Authentication can be done using parameters in the provider configuration or environment variables. Spacelift is also mentioned as a tool for managing Terraform infrastructure, supporting Git workflows, policy as code, programmatic configuration, context sharing, drift detection, and more features.
