Modern network architectures have become increasingly distributed, requiring localized routing configurations to manage growing
traffic loads. Global Load Balancing (GLB) can be used to harmonize traffic flow across your distributed resources and create
custom routing rules for different locales.
... harmonize traffic flow across your distributed resources...
GLB combines GeoDNS routing logic with load balancing techniques to manage traffic flow on a global scale. Whenever a user
queries your GLB records, they will be answered by nameservers in their originating region and will receive a response specific
to their locale.
GLB can solve many problems for distributed networks, such as:
Answer queries in the user’s originating region
Direct users to the server/resource closest to them
Steer traffic towards resources with higher capacity or are more cost efficient
Block potentially malicious traffic by location or IP address
