In today’s data centers, regardless of their size, there is an important and obvious fact: organizations are definitely not going back to a physical-only world. Since early 2000’s, when virtualization started to become widely popular, organizations noticed how server deployment and service provisioning speed improved exponentially when using VMs as opposed to physical hardware configuration and racking. By making use of templates, VM cloning and other features, network admins were able to deploy applications faster, more easily and more reliably.

In recent days, the set up and management of virtual environments has also evolved, allowing organizations to effectively and automatically migrate applications in order to take advantage of the lowest-cost redundant path and also for failover purposes when a disaster scenario arrives. Automatic and live migration of physical servers is, as expected, impossible, as it requires a network administrator to set up and rack another server in different network location and, (if moving it across different subnets) IP settings and routing table modifications that will all need to be coordinated properly in order to minimize the amount of downtime. On the other hand, virtualization offers capabilities such as live storage migration, fault tolerance, high availability, and distributed resource scheduling which increases services uptimes.
On a similar note, if an organization is in need of hosting its own private cloud, the flexibility to automate provisioning, grow on demand track, and potentially charge for, resource usage, make virtualization a more attractive proposal.
Even when thinking about the “green” trend that is currently dominating businesses, virtualization plays an essential role, assisting in reducing energy usage and rack space, which is an important reason for organizations constantly moving away from physical deployments straight towards the virtual world. Moreover, lower energy and empty rack spaces make replication sites (DR) easier and cheaper to deploy.
Given all of these benefits, it is almost impossible to think of a modern network environment that does not include virtualization. Exinda, as a global application performance leader, understands the virtualization needs of our customers and delivers virtual appliances that optimize your network for deployment within the most commonly used hypervisor vendors, including VMWare vSphere (versions 5.5 and 6.0), Citrix XenServer (versions 6.0 and 6.2) and Microsoft Server Hyper-V (2008 R2 and newer).
