Vercel Data Storage: Integration Guide and Storage Options Comparison
· 6 min read
Deploying application servers in a serverless environment like Vercel requires a shift in how we handle database connections. Traditional relational databases expect long-lived, persistent TCP connections. In a serverless or edge runtime, functions spin up on demand and shut down immediately after returning a response.
To prevent database connection exhaustion, Vercel leverages a specialized suite of serverless and edge-compatible storage services. This guide explains how database integration works on Vercel, details first-party storage options, and provides a decision matrix to help you choose the right tool for your project.
