In the wake of the recent economic recession, businesses today are seeking ways to do more with less. While these endeavors have been carried out with varying degrees of success, one area that can help is increasing the efficiency of enterprise technology, especially through virtualization and cloud computing.
Technology blogger Bruce Boyers recently asserted that virtualization and cloud computing technology can be leveraged by organizations to reduce cost of IT operations without sacrificing efficiency. He noted that in recent years more companies have chosen virtual rather than physical machines to host IT solutions and applications.
However, even as this trend continues, Boyers warned, companies must factor in several considerations that may affect the success of virtualization. One of the chief factors is fragmentation.
A company that is not mindful of fragmentation risks both performance and reliability from its virtual machines. Additionally, he said, the speed of the virtual machine can be seriously impeding, creating widespread problems for all relying on the virtual device.
This has become a bigger issue in recent years with the growth of advanced mobile technology. While virtualization allows employees to access company information through nearly any device with an internet connection, it can also bog down systems if an organization ignores the issue from fragmentation.
"Once the solution to fragmentation, traditional defragmentation won't fully address I/O issues in virtual environments," Boyers wrote. "Beyond fragmentation, I/Os need to be prioritized, coordinating shared I/O resources. Another condition peculiar to virtual environments that results from fragmentation is virtual disk 'bloat.'"
Data security is also a concern when it comes to virtualization. Given the relative youth of the technology, many companies are not yet sure how to secure their virtualized machines from data loss. In response to this, the PCI Security Standards Council recently published a guidance report detailing the risks of virtualization and best practices.
