8. Multi-Site Considerations : 8.2 Scenario #2 – Multi-Site Common Set of Services : 8.2.4 Synchronizing Catalogs
   
8.2.4 Synchronizing Catalogs
Synchronizing catalogs between sites is a time-consuming task. When setting up multiple vCloud sites designate one site as the master site for vApp template creation, and designate all other sites to be replication peers. If possible, leverage native storage array replication to replicate the vApp template storage in each catalog. Array replication can provide several benefits for long distance data movement, including data deduplication and compression. After synchronizing the data, leverage the catalog synchronization workflows provided by VMware vCloud API to import the replicated templates into the appropriate catalogs in vCloud Director.
Synchronizing templates added at remote sites is out of scope for this version of the reference architecture. VMware Professional Services can assist with the creation of these workflows.
