In the blog post by Nader Dabit, readers are guided through the process of deploying a Gatsby site to AWS using AWS Amplify, a versatile platform that combines a client library, CLI toolchain, UI components, and CI/CD hosting capabilities. The article begins with creating a Gatsby project and progresses to setting up hosting on AWS by pushing the project to a GitHub repository and managing deployments via the Amplify Console. Amplify streamlines the deployment process with built-in CI/CD and allows for automatic new builds when changes are pushed to the master branch. The post also suggests exploring additional features like authentication and GraphQL APIs through Amplify's CLI and client libraries, and offers resources for managing multiple environments or teams.
