More and more businesses are embracing private cloud solutions for security and customization needs. For many, it enables them to bridge the gap between efficiency and a need to keep their critical data in a highly secure environment.

Private cloud offers numerous significant advantages, including reduced overhead costs, faster server deployments, and higher levels of resiliency. What is often overlooked is how the Private Cloud can radically transform IT disaster recovery in terms of considerably reduced costs, more rapid recovery times, and improved testability.

Let's discuss in detail how private cloud can help in making your disaster recovery plan more concrete:

When business applications are uploaded and run on a private cloud solutions to enjoy some of the key attributes which substantially redefine the approach to disaster recovery:

The servers are virtualized, wherein a virtual machine is created that acts like a real computer with an operating system and other required software applications.

  -  Typically (however not required) the cloud runs on a standard set of hardware hosts and the private cloud footprint can be extended with simple addition of an additional host.

  -  In fact, most of the private cloud implementations are operating smoothly through a dedicated SAN and cloud controller. The virtualization of private cloud facilitates the user with key benefits of bare metal restoration without any need to connect with any particular hardware. Interestingly, these virtual server can be backed up as a snapshot that comprises of the operating system, applications, system registry and data, and restored on another hardware host very swiftly.

Undoubtedly, this has opened new paradigms for disaster recovery and business continuity. Here are some of the key aspects that you need to pay heed to:

  -  Offsite Backup - One of the fastest and simplified ways to stay reassured about data safety is to back up the servers to another date center that is geographically away from your production site. In any event of unexpected catastrophe, new hardware will need to be placed to keep the system running, which might prolong the recovery time depending on the hardware availability during the time of catastrophe.

  -  Dedicated Warm Site Disaster Recovery - Fundamentally, this aspect actually encompasses positioning of hardware servers at the offsite data center. In case a calamity arises, the backed up virtual servers can be rapidly reinstated to the host platforms. One compelling benefit to note here is that it is not at all required that the hardware should match the production hardware. The disaster recovery site can accordingly use a scaled down set of hardware to host a number of virtual servers or run at a slower throughput as compared to the production environment.

  -  Shared Warm Site Disaster Recovery - In this case, the private cloud vendor delivers the disaster recovery hardware at a discrete data center and segments the hardware among various users on a first come first serve basis. Since most DR hardware lies idle and all users usually don't experience a production disaster at the same time, the warm site servers can be offered dedicated solution at a minimal cost simply by sharing the platforms across multiple users.

  -  Hot Site SAN-SAN Replication - Even though, this provision is bit more expensive relatively to the warm site disaster recovery, SAN-SAN replication between clouds at the production and DR sites provides the prompt recovery and lowermost data latency between systems. Depending on the recovery key objectives, the secondary SAN can prove to be a cost effective option in terms of the volume and type of storage, and the number and size of physical hardware servers can also be scaled down to accommodate a poorer performance solution in the event of an unexpected disaster.


Make your disaster recovery and business continuity plan more potent and robust by embracing the private cloud model.
