Delivered Savings and Benefits through Virtualization

Network Virtualization is a trend that is sweeping through enterprises as the corporate world is discovering the economic and security benefits possible by consolidating their multiple physical servers into “virtual networks”.  Savid applies its comprehensive virtualization knowledge and solutions to deliver these advantages to your business.

It was once necessary for companies to own and operate multiple servers for various enterprises. These traditional servers only host single applications running on operating systems such as like databases, ecommerce applications, email, web servers, and dedicated legacy systems.  Sprawling many servers across datacenters incurs immense costs from procuring the hardware, operational and management expenses, and maintenance fees.  Multiple servers raise facilities costs by consuming power, space, and cooling as well as escalate the vulnerability of your networks.  Yet, because these expensive servers are not built to the scale of their usage, they only utilize 5 to 15% of their actual hardware power on average.  You are paying high costs to maintain these servers, while they are wasting 85 to 95% of their potential. 

Economic Benefits through Consolidation

Virtualization was developed as a solution to hardware underutilization, expanding management and maintenance costs, and network vulnerability.  Savid’s network virtualization creates a layer of abstraction that emulates physical divisions among networks so that multiple networks can operate on the same physical hardware – rather than requiring separate machines for each one.  Diverse operating systems run in isolation, side-by-side on the same physical machine.  The hardware resources of the machine are combined and reallocated to the various virtual machines as necessary.

Savid finds the average ratio for consolidation is 15 machines to 1.  Imagine reducing 600 servers down to just 40.  Or, instead of maintaining eight machines at 10% usage, a single machine operates at 80%.  This reduction in hardware not only saves companies from purchasing expensive new machines, but cuts ongoing maintenance costs in power, space, and cooling.  Also, with fewer machines, fewer personnel are needed to administrate them.  Virtualization can result in savings of 40 percent or more on average in per-user costs per month.  Companies find the return on investment for Savid’s virtualization to be less than 3 to 6 months on average.

All enterprise networks are unique that run a different number of systems for different purposes.  VMware has created a virtualization calculator to help you determine how much your business could save through virtualization.

Security Benefits through Virtualization

In addition to these economic benefits, virtualization also has inherent security advantages found in configuration, encapsulation, and portability. 

By distributing various functions such as middleware, databases, and front-end web servers into separate virtual environments, administrators can configure different security settings necessary for each environment.  If a particular virtual machine does not require access to the internet, for example, it can be configured to prohibit internet access and reduce the risk of net-spawned infections.  User permissions can separate work and personal environments by giving unique levels of trust to each.  These network perimeters can be defined to isolate virus and spyware attacks from company resources

Virtual machines operate on their own partition of virtual hardware, RAM, CPU, NIC, etc.  This layer of abstraction limits access to the physical hardware – so even if a virtual hard disk is corrupted by malicious software, the physical hardware remains intact.  Likewise, data does not leak across virtual machines as applications can only communicate over configured network connections.  If one virtual machine crashes or becomes infected, it cannot harm the other networks. 

A virtual machine’s full system (operating systems, BIOS, virtual hardware, configured applications) is encapsulated and can be saved onto a single file for back up.  This makes it easy to save, copy, move, and maintain a virtual machine.  If security is breached or malware is installed, you can roll-back a virtual machine to a particular point in time before the accident occurred – or simply reload your virtual network for instant disaster recovery.

Rely on Savid to Deliver the Benefits of Network Virtualization

Today, virtualization has a position of great prominence with businesses optimizing their global IT infrastructure for maximum utilization, security, and flexibility.  Already, close to 100 percent of the Fortune 1000 use some form of virtualization and 75% of companies with over 500 employees are currently deploying virtual networks. 

Now, you can rely on Savid’s comprehensive knowledge to actualize the power of your underutilized hardware and realize new security and control benefits through virtualization.  Savid employs VMware software to deliver virtualized networks for companies that are isolated and encapsulated on the same physical machine.  It takes weeks to acquire new hardware, install operating systems and patches; but Savid’s virtualization can be instantiated in a matter of minutes.  We pilot test virtualization to give your administrators a chance to practice and get comfortable with the technology and ensure a smooth deployment.  End-users will connect to a dedicated network that provides connectivity to all the resources the user requires.  Network administrators can easily create, modify, and adapt virtual environments to suit different groups of end-users.
