You're totally right about connecting to your database from the edge. That said, I think JS is quickly becoming the target for a lot of hosted runtimes because it is so easy to sandbox and has the option to drop down to WASM for high performance and indirectly supporting other languages. Cloudflare Workers (and Fastly, and Superfly, and and and) are all following that path at the edge, but I think as the consensus builds around JS + WASM as a server runtime, we might see the same style of environment for more traditional workloads that might wanna connect to databases.
