What Is Virtualization And Cloud Computing?
Virtualization is an emerging IT paradigm that separates computing functions and technology implementations from physical hardware.
Cloud computing, for example, is the virtualization of computer programs through an internet connection rather than installing applications on every office computer.

Why Virtualization? Cost Structures
Virtualization can have a drastic change on how business pays for its technology and handles the associated risk.
First, by removing the hardware associated with IT functions, capital costs are virtually eliminated.
Second, the remaining costs are strictly transferred into an operating expense with on-demand or subscription based cloud computing applications.

Why Virtualization? Efficiency
Businesses that focus on technology can usually leverage their expertise to utilize efficient computing and IT resources. For the rest of us, that advantage is not the case.
Virtualization firms are specialized companies that can pass on cost savings, know-how, best practices, and energy efficiency to clients. Operating expenses can be lower with cloud computing than an in-house system.

Case StudyEmail Archiving and Data Storage
To understand the benefits of virtualization, let us examine an application of cloud computing.
Email archiving and personal data management can occupy 90 minutes out of every worker’s day.
Email archives can easily top 5 TB (that’s roughly 5,000,000 MB) worth of messages, reply-alls, carbon copies, and attachments.
Periodic data backup and maintenance can take over 8 hours and more than double that time for operational recovery.

How Email Archiving Becomes Expensive
In the above environment, data is spread across multiple sources, leading to duplication, inefficient storage practices, and possible data loss:The email server houses recent and saved files.
Data exists on every user’s hard drive in the form of exchange archive files, or .pst.
On-site backups, such as removable drives, CDs, or dormant hard drives, occupy a good portion of saved data.
Off-site backups for long term data storage can also be far-flung.

Optimizing Data Storage
Optimized, cost efficient data storage would look like this:
A single location for all archived data on the most cost effective storage device type.
Duplicate data removed and related messages merged to reduce file sizes.
A single, always-on access point.
Quick, painless, and automatic periodic updates with new data that integrates with existing information.

How Virtualization Achieves Optimal Data Storage
Virtual data storage operates similar to a bank:
A client would bring their data to a cloud computing firm who would store it.
The technology company would take that data, optimize it, and merge it with the client’s existing data storage.
When the client needs to get their data, a single internet access point delivers the required email or file.
To streamline the process, periodic data archiving can automatically occur to keep the stored information current while creating a turn-key operation.

Instant Results
Combining, sorting, compressing, and removing duplication within data will provide instant results. Compared to the first scenario, a unified, low cost data structure would look like this:
Size: 2 TB
Backup Window: 3.5 hours
Number of Exchange Messages: Reduced by 86%
Size of Files and Messages: Reduced by 80%

Improved Data Reliability And Recovery
Data security and reliability have become important issues in the global economy. Cloud computing improves upon them both:
Virtualization removes the liability from a single, physical server that can be subject to natural disasters, power failures, and accidental damage.
IT best practices and standards provide up-to-date data security powered by the know-how of specialized technology firms.

The Bottom Line
Virtualization and Cloud Computing open up new possibilities and opportunities for businesses to utilize technology like never before.
Costs, risks, and barriers to entry can be knocked down for small and medium sized businesses.
All companies can benefit from efficient operations along with improved reliability and security.
