A set of vCloud Air services designed to offer enterprise users a highly scalable and adjustable DRaaS solution that can displace the requirement for a secondary data center. Part of what makes this solution powerful is that users have the capability to save their on-premises vSphere environment in various ways depending on a workload’s needed Recovery Point Objectives and recovery time objectives targets. The other key intensification is the improved performance and scalability that this solution can accomplished by incorporating hybrid cloud manager and their hybrid DMZ reference design.

Protecting the Data Center in the cloud:
Many vSphere users have a broad set of applications in their on premises data center from mission critical workloads to test and development workloads. When it comes to saving those workloads and ensuring business continuity through a major event, different workloads will have different requirements. There are three primary methods of protecting the data center workloads:
- Leverage vSphere duplication over a WAN optimized connection for improved performance
- Disaster avoidance through planned migrations, either with Zero or low downtime
- Support active application availability where available
By leveraging the SD-WAN abilities of Hybrid Cloud Manager, this new solution is capable to ameliorate upon the standard vSphere duplication application appliance.
Replication/duplication based DR offers two different types of protection. As data is regularly being synchronized with a copy that is sitting in vCloud air, if the primary data center goes down anyone will always have a copy to recover from in the cloud. If RPO target was 15 minutes, the copy in vCloud air will be at most 15 minutes out of sync with what was running live. When a virtual machine is already configured for duplication and needs to be immediately moved to the cloud side, choosing to do a planned migration will do an optional final sync.
Migrate Workloads for Disaster Avoidance:
This new solution offers new methods of disaster avoidance by taking advantage of the three migration methods provided by Hybrid Cloud Manager with the own migration of a 20GB test VM, migrations happened in less than 5 min. an absolute review done by correct technologies showed up to 70% decrease in transfer times with HCM’s WAN Optimization.
Cross Cloud vMotion:
Amplify a layer 2 network with HCM into their vCloud Air environment also allows for cross cloud vMotion. Like an on premises vMotion, the VM is moved and during this time it may drop a few pings. In addition to an amplified network, cross cloud vMotion also needs hardware Version 9 or higher. One cross cloud vMotion can be performed at a time; with other adjoined up to immediately start once the current cross cloud vMotion is completed. Once a cross cloud vMotion is finished the VM is detached from on – premises.
These are achieved on a VM that is turned off. When the migration is completed, the VM is moved to a migrated VMs folder.
Low Downtime Migrations:
It takes advantage of duplication or replication technology. When configuring a virtual machine for a low downtime migration, the VM does an initial sync then performs delta sync before the VM is migrated. This gives the option to set a change window to perform this last sync.
Active – Active Configurations:
There are certain applications like share point and SQL server that support Active – Active availability groups which is an in application tech. that supports distributing workloads across different data centers for distributed protection. With dedicated disaster recovery solutions, one can support mixed modes of active workloads alongside duplicated and migrated workloads. That means that these workloads can co exist directly with duplicated and replicated VMs in the same Virtual Data Center.
