How to Choose the Right Virtualization Solution for Your Business
Not all virtualization technology works the same way. As every IT environment is tremendously different and his its own unique operating patterns and technical compositions, there is never one ideal solution for every IT scene. Instead of searching for the perfect solution, it is a better to choose the right solution for a specific situation. There are several things that influence the choice of virtualization software:
Mobility and Motioning
Motioning facilitates applications to shift between physical servers without disruption. There are instances when motioning can cause volatility and generate troublesome challenges for management groups tasked with incident management and compliance issues. Organizations need to first analyze maintenance windows, consistency of workload patterns and disaster recovery strategies to determine whether motioning is a good choice in the environment.
Windows Maintenance
Maintenance windows become intermingled when combined on a single physical platform, and this creates a situation where there is no window of time available for hardware maintenance. The same problem arises for software freezes. It is therefore vital to make the right placement decision, as the mere act of motioning may amount to a change that contravenes a software freeze.
Disaster Recovery Strategy
Motioning can destabilize the efforts of application level reproductive or hot spares, if they are a part of the disaster recovery plan. To circumvent such consequences, organizations need to go through a detailed assessment of disaster recovery strategies, roles, cluster strategies, cluster roles and reproductivestructures.
Overhead and Scalability
The success of virtualization can be impacted by numerous aspects of any operational model. That can include the way input and output is handled, the highest number of CPUs per VM or even the way vendors license their software on the platform.
Software Licensing Models
Some virtualization technologies do not support certain applications. Software licensing models may play a major role in the ROI gained from desktop virtualization, even if support isn’t an issue. For instance, applications are usually licensed per physical server, and this in turn radically diminishes any hopes for gains from virtualization endeavors.
Security
Organizations often have little assistance for ensuring security in a physical-to-virtual transition, as there are no published guidebooks or best practices for securing a virtual environment. Security zones and information privacy need to be considered to minimize risks.
Chargeback Models
The lack of feasible chargeback models is often an important and unexpected issue arising from virtualization. This means virtual environments must be designed so that they do not cross departments. The solution must provide a way to obtain accurate utilization information to ensure equitable billing for computer resources, provided the chargebacks are in place.
Choosing the right virtualization solution is often a confusing and overwhelming task due to the large volume of virtualization offerings. By analyzing the key factors impacting the virtualization efforts, critical missteps can be avoided, and a more informed and complex decision can be made. Ultimately this makes a huge difference.
