vCloud Availability for Cloud-to-Cloud DR-Part 1:Introduction

VMware vCloud Availability for Cloud-to-Cloud DR is the latest addition in VMware Cloud Provider Platform portfolio and it was first released in May 2018 and it brought joy for the service providers who wanted a VMware native Cloud to Cloud DR solution for vCloud Director based clouds from long time. 

What is vCloud Availability for Cloud-to-Cloud DR (vCAV-C2C)?

VMware vCloud Availability for Cloud-to-Cloud is a solution for DR between 2 instances of vCloud Director. Cloud to Cloud DR concept is not new but VMware did not had any solution for vCloud based cloud. vCAV-C2C fills this gap and helps VMware Cloud Providers to leverage existing vCloud Director environments to provide DR services, including replication and failover capabilities for workloads at both VM and vApp level.

Following are the main capabilities of vCAV-C2C solution:

1: Replicate and recover vApps/VMs between two vCD instances for migration, DR, and planned migration use cases.

2: A unified HTML5 portal which tenants can use for managing Replication, migration, and failover for vApps/VM’s. 

3: A simplified architecture which supports vCloud Director 8.20, 9.0, and 9.1 alongwith support for vSphere 6.0U3 and 6.5U1.

4: Symmetrical replication flow that can be started from either the source or the recovery vCloud Director site. Each site can act as both source and destination for replication.

vCloud Availability for Cloud-to-Cloud DR Architecture and Components.

Below diagram from VMware provides a holistic view of vCAV-C2C architecture.


In each site following appliances are deployed and they operate together to support replication, secure communication, and storage of the replicated data.

  • vCloud Availability Replicator.
  • vCloud Availability Replication Manager.
  • vCloud Availability Replication Service/Manager.

With vCAv-C2C, everything is packaged into a single OVA (Photon-based appliance) with a full GUI driven installation. 

  • For lab and POC deployments, you can use vCAV-C2C in combined mode where all roles are configured in one appliance.
  • For production deployment, you can spread the roles by deploying multiple instances of ova and only selecting specific role.
