Hashicorp Terraform is an IaC tool that allows engineering teams to define and deploy their application environments using a declarative, human-readable syntax. Throughout this guide you've learned how to use Terraform for building serverless applications.

• How to add various resource types and build a decoupled serverless architecture
• How to implement synchronous APIs with API Gateway, and async processing with SQS message queues
• How to wire application components to work together while following the principle of least privileged IAM access
• How to test your applications locally with AWS SAM
• How to deploy your applications to AWS, and test them running in cloud
• How to add observability aspects, such as logging and tracing, to your applications
• How to elevate your Terraform templates by adding modules, supporting multiple environments, and separating infrastructure and application code.
