The small and medium businesses (SMB) are unique in their approach to virtualization. In attending a recent VMware Users Group (VMUG) meeting it became clear that virtualization is much easier to embrace for the large enterprise, whereas the smaller IT shops have an entirely different dynamic. Here are three strategies currently employed by the SMB while approaching virtualization:
The SMB may not have the money to jump into an enterprise virtualization management suite, so the free tools work nicely in their environment. Free tools such as VMware Server, Microsoft Virtual Server, and Citrix XenServer Express Edition offer virtualization at various levels that will generally meet requirements. The free virtualization packages have their benefits, but there also are limitations. These limitations revolve around storage management, high availability and redundancy.
Cite disaster recovery
The SMBs present at the VMUG frequently used disaster recovery to justify the upfront expense for decent virtualization management software. Disaster recovery tends to present a better argument for funding rather than simply stating that management software for virtualization technologies are superior to that of the free equivalents.
All or none
SMBs tend to shoot for an all or none approach to virtualization. If utilizing virtualization, serious reasoning is required to explain why a server can and should not be a virtual system. This correlates to the hardware purchases. In this situation, all new server purchases must be capable of the virtual host role regardless of the immediate availability of the desired end-state of the virtual environment.
It is tougher for the smaller IT shops
The smaller organizations have a particular challenge taking the virtualization plunge due to smaller budgets. The challenge for SMBs is to find a way to justify the expense and not in using virtualization itself-the benefits are obvious. The most difficult step, however is to get a business buy-in for the potential added expenses, and this is where SMBs should focus their efforts if they are trying to convince executives to use a virtualized system.
