The Art of Data Residency and Application Architecture

In this post Rob and Paul explain how they built Silo, a fully functioning multi-region Next.js application combining CockroachDB multi-region serverless and a multi-region Node.js (Lambda) API backed by a Geographically aware Route 53 Hosted Zone. Both the API and CockroachDB have been deployed to AWS. The Next.js app has been deployed using Vercel.

There are a number of reasons why you’d want to choose a multi-region strategy; to optimize latency, maintain high availability and, in some cases, to comply with regional regulations. But, rather than tell you about the benefits, I’d like to show you.
