Bringing the benefits of open source virtualization to business
For many companies, the largest benefit of server virtualization, which allows multiple operating systems to be installed on a single server, is in reducing the amount of hardware that is required to run all the software needed by the business but Virtualization’s impact extends beyond the immediate savings in hardware. With fewer servers to maintain, you can focus on innovation rather than maintenance.
Consolidating servers using a virtualization process not only provides savings in terms of how many physical machines must be bought and maintained, but also potentially reduces the amount of physical space that a company needs for its servers or data centre.
There are many benefits to consolidating the number of servers in your environment by taking advantage of the many different open source virtualization techniques (i.e. Xen,Quemu,KVM ) on the market.
How can virtualization improve your business?
- Reduction in number of physical servers – you can reduce hardware maintenance costs because of a lower number of physical servers.
- By implementing a server consolidation strategy, you can increase the space utilization efficiency in your data center.
- You can develop a standard virtual server build that can be easily duplicated which will speed up server deployment.
- You can deploy multiple operating system technologies on a single hardware platform (i.e. Windows Servers, Linux Servers).
- By taking advantage of server virtualization you can easily improve the efficiency of your Data Center, as well as lower your cost of ownership.
- You can focus on innovation since you do not have to spend time in maintenance of many servers.
- Because virtualized applications are isolated both from other applications and the underlying operating system, the need for pre-deployment testing is eliminated, and the processes associated with application deployment, version changes and updates are significantly accelerated. All of this equates to improved application maintenance, reduced supporting costs and also increased user productivity due to less downtime waiting for IT to update applications and solve conflicts.
- Optimizing license management: Tracking license compliance and re-harvesting unused licenses can be a significant drain on IT resources, and allowing unused licenses to sit idle can be even costlier. Endpoint virtualization, in addition to providing all the benefits of virtualization, can also give IT the ability to centrally manage and dynamically track licenses and ensure license compliance.
- Lowering user downtime due to application recovery: Occasionally an application crashes despite being isolated from the rest of the system due to an outside cause. For example, a Web browser that encounters an issue while being used to do research online. With endpoint virtualization, that Web browser can be virtualized so that the problem that application encounters will not affect the rest of the system. Additionally the program can simply be reset and returned to the normal operating state without having to be reloaded. This can even be done by the end-user, allowing instant self-remediation.
- Better Security. The ability to telework assists government agencies in becoming more efficient. As business across the globe is directed to keep their communications transparent, it must find a way to keep the information secure. Enterprises are finding that a well managed workspace is a secure workspace. Technology such as virtualization helps IT departments to set up solid endpoint controls. Leaving security to users can be dangerous so having controls in place to secure agency information is essential.
- Virtualization helps enterprises become more agile by providing the ability to work remotely from any location. Employees can access their applications anywhere, anytime, on-demand. This approach, which requires only a single connection and efficiently utilizes server and connection resources, ensures that users obtain consistently reliable access to applications and data.
- Many times, it is essential that end users have easy desktop access and management capabilities. In the past, managing this access was tedious and time consuming. Now, many enterprises have eliminated much of the manual work associated with application management by deploying virtualization technologies, saving thousands of technician hours each year.
- There are many benefits to storage virtualization which can help enterprises to: reduce data center complexity and improve IT productivity by managing multiple physical resources as fewer virtual resources; meet rapidly changing demands by dynamically adjusting storage resources across the information infrastructure; increase the efficiency of storage by letting files be stored wherever there is room rather than have some drives go underutilized; guarantee anywhere access for disaster recovery applications; spend less time managing storage devices since some chores can be centralized; and provide one view into the data center.
- Another area of computing that can reap large benefits from virtualization is product testing. The testing part of a computing project is often requires extraordinary endeavour that requires relatively expensive resources, and a lot of time. Virtualization tools allow software testers to quickly and easily set up and maintain testing environments, and to rapidly restore testing environments to their original state when required.
Since computer virtualization allows a variety of operating systems and software configuration settings to be used on a single machine, application virtualization provides a much more flexible way for companies to run applications. Without virtualization, for example, a company might need to bear the cost of running five separate servers with different operating systems, or different configurations in order to run all of the applications needed for the operation of business.
The flexibility benefits of virtualization mean that all those operating systems and applications could potentially be run on a single piece of hardware. As such, efficiently using hardware is one of the biggest benefits of virtualization.
