Vercel Database Strategy: Avoiding the 502

If your manifestation site gets viral traffic, your database is the first thing that will break. Here is how we prevent it.

The Serverless Bottleneck

In serverless environments like Vercel, every function call creates a new database connection. Without pooling, you will hit your connection limit in minutes. Using tools like Prisma Data Proxy or Upstash allows for thousands of concurrent connections on a standard plan.

Latency Optimization

Regional database placement (e.g., placing your DB in the same region as your Vercel deployment) can reduce response times by up to 80%.
