The blog post presents a detailed guide on setting up an AWS S3 bucket for storing Postgres backups, specifically in the context of automating nightly backups for multiple Neon projects. The article outlines the process as part of a two-part series, focusing on configuring AWS components, such as creating an OIDC Identity Provider to authenticate GitHub Actions and establishing an AWS Role to delegate permissions for accessing AWS services. It also explains creating an S3 bucket, updating its policy to allow specific actions by the Role, and highlights the importance of managing geographical regions to optimize backup efficiency. The post concludes by emphasizing the use of GitHub Secrets to securely store sensitive information like AWS account details and bucket names, and introduces Neon as a serverless platform for Postgres with features like autoscaling and database branching.
