Computing at the Edge is one of the most exciting capabilities in recent years. CDN allows you to keep your files closer to your users. Edge computing allows you to run your applications closer to your users. This helps developers to build globally distributed, performant applications.
Similar to Serverless functions (AWS Lambda etc.), Cloudflare Workers are stateless. As you can see in Cloudflare’s survey, developers are asking ways to connect their databases from Edge functions. Unfortunately, most databases are not designed for serverless environments, they require persistent connections. We developed the REST API over Redis to enable serverless edge functions to access Upstash in the simplest and fastest way possible.
