We have IT departments of every size today looking for ways that they can utilize the cloud either because they want another tier of infrastructure or they have a mandate from their executives that says that we’ve got to have a cloud strategy.
One of the best use cases for cloud in the enterprise today is around Disaster Recovery (cloud disaster recovery). Now most organizations don’t have the budget to do that and therefore they haven’t been applying the Business Recovery Plan effectively for some time now except for the mission-critical applications.
By leveraging cloud you can not only do more cost-effective Disaster Recovery for those applications that you’re doing it for today but you can bring disaster recovery to applications for which you didn’t have the resources to do disaster recovery for before.
A Virtualization tool such as Microsoft’s “Hyper-V” allows you to do on the fly P2V migrations, and the way it works is during the backup process it captures not only the files that are inside of a particular host or inside a particular Virtual Machine (VM) but it also captures system configuration data, things like CPU configuration, your memory configuration and network configuration. All the different pieces of metadata about the system.
That metadata is then used to construct a VM with the same specifications as the “Physical Box” or the “VM”. Therefore a container is created and then you can run a restore inside of that container that’s provisioned. But with a Virtualization tool you automate all those steps and it’s actually a one-click process to create those VMs at the secondary site (the Cloud).
You run your backups and you can provision a secondary copy of Disaster Recovery in the Cloud site in a VM from your “Physical or Virtual Machines” sites.
With a Cloud Disaster Recovery solution you can get replication and Deduplication such as Dash Copy or array based replication. You get your Data from the primary site to the secondary site and the secondary site can be either private or public cloud and then you can automate and schedule restores at the secondary site to validate that you have a successful Disaster Recovery operation (Testing).
You use automated workflows for a single VM and replicate that across or replicate the same process across multiple VMs to give you more scalability and take a lot of the manual steps out of the process.
