Hybrid cloud deployment for hybrid unified communications

One or more non-transitory machine readable media having instructions executable by at least one processor to perform a method of deploying unified communications (UC) in a hybrid cloud, the method comprising:

• independently managing a set of regional UC resources implemented in each of a plurality of regional UC virtual data centers, associated endpoint devices being registered to utilize UC services deployed in at least one respective regional UC virtual data center and to employ corresponding regional UC resources thereof, operating in at least one service cluster of the respective multi-tenant regional cloud, to communicate real-time media traffic with respect to the associated endpoint devices;
• globally managing each of the plurality of regional UC virtual data centers and coordinating orchestration of UC resources between and/or among the regional UC virtual data centers;
• independently monitoring, at each of the plurality of regional UC virtual data centers, utilization of respective regional UC resources to provide status information based on the utilization of resources;
• and
• controlling, at each of the plurality of regional UC virtual data centers, scaling of the set of regional UC resources based on the status information monitored for each respective regional UC data center.
