Virtualization 1.0 provided an early taste of the value of application mobility by allowing the live migration of virtual machines to alternate hosts. But that mobility was confined to a single hypervisor, and for the most part a single data center. In virtualization 2.0 we want to set that application free, allowing it to move between hypervisors and even outside the data center to managed service providers (MSP) or public cloud service providers (CSP).
What is Virtualization 2.0?
At Storage Switzerland, we talk a lot about the next wave of virtualization where the focus is on more than just server consolidation and improved application availability. In the next wave, “Virtualization 2.0”, we want that return on investment (ROI) to lap the initial ROI that made virtualization 1.0 such a success. This can be accomplished by increasing VM density and it can also be done by enhancing application or virtual machine mobility.
The Value of Application Mobility
There are many benefits that almost any sized data center can reap from application mobility. The most apparent is disaster recovery, the ability to have an application on standby in a separate facility, be it the organization’s site, an MSP, or a CSP like Amazon. Service providers are ideal targets because they typically manage a well maintained multi-tenant data center and they typically charge by computing resources used, which for a standby system would be almost nothing.
Cloud bursting is another use case. This allows an organization to quickly move an application to an MSP or CSP for additional compute resources to address a spike in demand. Cloud bursting is ideal for seasonal workload spikes and allows data centers to build for normal demand instead of just a worst case scenario.
The Key is Agnosticity
The keys for application mobility to truly work is complete agnosticity from the underlying storage resources, the hypervisor, and the location. To be agnostic requires encapsulating the virtual machine metadata and abstracting it from the day-to-day environment so that it can be easily transported.
