Serverless Compute with AWS Lambda and Prisma

The Serverless paradigm, primarily driven by services like AWS Lambda, allows developers to focus purely on business logic without managing underlying infrastructure. However, stateful applications—especially those connecting to a traditional relational database—require careful handling. ## The Database Connection Problem In a traditional server, a single process maintains a fixed pool of database connections. In a Serverless environment, a new Lambda container (or a cold start) might be instantiated for *every* incoming request, leading to a surge of database connections that can quickly overwhelm the database. ### The Prisma Solution: 1. **Prisma Data Proxy:** This is the recommended, zero-config solution. It manages a persistent connection pool for you, routing all Lambda requests through a single, intelligent gateway. 2. **AWS RDS Proxy (Self-Managed):** A similar service offered by AWS that sits between your Lambda functions and your RDS database, managing the pooling and multiplexing of connections. ### Deployment Workflow Use the Serverless Framework or AWS SAM (Serverless Application Model) to define your infrastructure as code. Ensure you configure a dedicated VPC for your Lambda functions and the database to maintain security and allow internal communication. This combination of Serverless compute and a managed connection pool gives you the scalability and cost efficiency of Serverless without sacrificing the reliability of a relational database.
