Run Fly.io Apps with Serverless Redis

Fly.io is a platform for globally distributing applications, and when paired with Upstash Redis Global Database, it provides a solution for globally replicated data. While standard Redis can be run as a Fly.io app, it is limited to a single region, making Upstash Redis a better fit due to its global replication capabilities and REST-based SDK that avoids connection issues in stateless runtimes. The text outlines the steps to create and deploy a basic Node.js application on Fly.io that accesses Upstash Redis, including setting up accounts, installing necessary tools, and modifying the application code to integrate with Upstash Redis. The deployment process involves launching the app locally and deploying it on Fly.io using the flyctl commands, with the option to monitor the application through Fly.io's dashboard. The article emphasizes the ease of using these technologies together to create scalable and globally accessible applications.
