Solution Overview

Solution Overview

Two-level cloud allows you to interconnect the local FusionCloud private cloud with FusionCloud API Gateway at the peer end when resources on the local FusionCloud private cloud are insufficient and apply for resources on the peer FusionCloud private cloud without expanding the capacity of the local resource pool to quickly meet burst resource growth requirements.

Figure 7-56 shows the logical architecture of the two-level cloud.
