Geographic Distribution Question

heybenross

Oct 13, 2023

The geographic example:

A multinational company has data centers in North America, Europe, and Asia. A load balancer directs users to the nearest data center based on their geographic location, reducing latency and improving the user experience.

In that scenario is there one load balancer? That seems bad because Asia would need to round trip to North America every time.

Or would there be a load balancer in each region?

This is a DNS Load Balancer, which means the initial request will resolve the domain name to the nearest server's IP address. All subsequent requests will go directly to the IP address, avoiding the additional roundtrips.
