Pro customers can now configure up to 3 regions for Vercel Functions

Introduction:

• Pro customers can now configure up to 3 regions for Vercel Functions, improving performance by running compute closer to distributed data sources.

Enhanced Performance:

• Users can now set up to three regions for Vercel Functions, allowing requests to be routed to the closest region, reducing latency and improving response times.
• Increased compute density leads to higher cache hit rates and lower cold starts, enhancing overall performance.

Compatibility and Redundancy:

• Support for multiple regions enables compatibility with standard database replication like Postgres read replicas.
• Adds an extra layer of redundancy to complement Vercel Function's built-in multi-Availability Zone redundancy.

Implementation and Deployment:

• To configure additional regions, add a property to the project configuration file and redeploy the project for changes to take effect.
• Learn more about configuring regions on Vercel's documentation.

Conclusion:

• The ability for Pro customers to configure up to three regions for Vercel Functions enhances performance, reduces latency, and improves overall reliability, providing a more robust and efficient compute environment.
