Cloudflare Workers and Edge Functions bring the Serverless model to the next level by letting developers deploy code instantly globally to give it exceptional performance, reliability, and scale.
Having server-side applications execute close to where their users are located brings greater performance and drastically improves the user experience of an app. However, due to their limited runtime environment, working with your favorite traditional database is challenging since it can’t be accessed in CloudFlare Workers directly. Prisma solves this problem in multiple ways.
The goal of the talk is for developers to understand what the Edge 
really
means, how it works, and how to work with your favorite 
traditional
database on the Edge.

Edge functions are pushing the limit of serverless computing – but with new tools, come new challenges. Due to their limitations, edge functions don't allow talking to popular databases like PostgreSQL and MySQL. In this talk, you will learn how you can connect and interact with your database from Cloudflare Workers using the Prisma Data Proxy.
