Introduced Vercel KV (serverless Redis), Vercel Postgres (serverless SQL), and Vercel Blob (edge file storage) as first-party storage solutions. Vercel KV is powered by Upstash and offers durability. Vercel Postgres is powered by Neon and integrates with Next.js Server Components. Vercel Blob provides an API for storing and serving files at the edge. The post also states that Vercel KV and Vercel Postgres products have been sunset and are now available through the Vercel Marketplace.
