Architecting a vCloud Availability for vCloud Director Solution : vRealize Orchestrator Configuration
   
vRealize Orchestrator Configuration
The vSphere Replication UI is provided within the vSphere Web Client of the on-premises vCenter Server. This is the primary interface for configuration of the replications in both to-the-cloud and from-the cloud directions.
There is, however, potential need for an additional interface that can be provided by vRealize Orchestrator for two main use cases:
Provider managed DR service
Tenant-initiated failover when the on-premises environment (including vSphere Web Client) is down and not accessible
vSphere Replication includes the vRealize Orchestrator plug-in with out-of-the-box basic workflows for replication configuration and recovery, migration, or test actions at the VM level. These can be combined into elaborate recovery plans thanks to vRealize Orchestrator workflow and orchestration capabilities.
The placement of vRealize Orchestrator impacts which workflows can be used.
