Overview

UCS distributes requests globally according to user locations and service policies across clouds and clusters, implementing intelligent traffic distribution and scheduling. It also schedules application access traffic across domains in real time on demand.

With Domain Name Service (DNS), user requests to the same domain name can be responded to by different backend clusters, according to the users' carrier and region. Such traffic splitting reduces the latency in cross-domain and cross-network access.
