It is universally recognized that virtualization helps organizations standardize data center operations. Unlike traditional data center infrastructures, the abstraction of computing resources orchestrates the emergence of a software driven data center that can be dynamically configured to allocate resources where they are most needed. As a result, there is a significant and upward increase in the number of enterprise critical applications that are being virtualized and in the effort to extend the benefits of the private Cloud to virtual applications.
Business critical applications that are candidates for virtualization are Microsoft Exchange, Microsoft SQL Server, Microsoft SharePoint, Oracle database, Oracle applications and SAP. Other business critical applications could include applications developed / customized by the user for business specific tasks. These are categorized as “critical” because even a temporary non-availability of the application would result in a loss of business. The virtualized versions of these applications will need to remain available, deliver optimum performance, and be manageable. In fact, the availability of the application must be enhanced by virtualization. The performance must be greater than or at least equal to the current performance and operations, such as application backup and restore or migration should not become problematic.
The Hypervisors that are currently being deployed by Cloud backup vendors, invariably, have the capability of meeting all these essential criteria non-disruptively, without resource constraints during infrastructure refreshes and optimal storage performance. Workloads can be scaled up or down with ease and downstream activities, such as replication or data restore can be completed without restrictions on performance or availability.
Cloud service providers provisioning for virtualized environments use cluster technologies with private Cloud models, to centralize the administration of the virtualized applications. This technology creates powerful clustering capabilities while provisioning for a single point storage management with effective / efficient performance and infrastructure scaling capabilities. The technology abstracts data access and management from the hardware and allows control of virtualized applications through software interfaces. Storage resources can be assigned on demand without encountering negatives such as downtime, reconfiguration or any kind of brute force mechanisms for data management. The technology is application aware, snapshot based with powerful, tested de-duplication for availability and reliability of data.
The bottom line: Underlying hardware and network infrastructure is managed by the Cloud backup service provider. Elaborate customer support systems with qualified system architects are available to help enterprises virtualize their application and ride on the private Cloud infrastructure. The virtualized application can be managed from within the Cloud service using user friendly, “single pane of glass” interfaces. Entire Virtual machines can be created, populated, optimized and recovered.
