Interview: Data center dos and don'ts: Virtualization

I recently had the pleasure of speaking with MiMi Yeh, from TechTarget's SearchOpenSource.com, about virtualization in the data center and the do's and dont's.

David Marshall and Wade Reynolds, authors of Advanced Server Virtualization: VMware and Microsoft Platforms in the Virtual Data Center, spoke with MiMi Yeh to help others with their experiences in the virtual data center.  They shared their best picks for deploying and managing virtual machines and they offer pointers on how to assess the scalability of virtualization products, where best to use them and how to secure them within a network. 

MiMi asked, "When is virtualization the best option for server consolidation?"

Wade Reynolds: We believe that software-based virtualization technology is the most cost-effective and flexible option available for server consolidation. As the technology matures and more standards are adopted, especially in the areas of APIs and virtual disk formats, barriers between the different virtualization platforms are being dismantled. Virtualized servers are less likely to be subjected to vendor lock-in relative to a blade or physical partitioning solution.

Through encapsulation, virtual machines (VMs) can be easily moved from host to host as needed, allowing you to take advantage of new server hardware without disrupting services. The best candidates for software-based virtualization server consolidation are under-utilized physical servers whose performance will not be impacted by running in a VM.

David Marshall: Consolidation was the early war cry from those of us in the virtualization business. But virtualization offers so much more than just server consolidation. Companies are only now realizing all the problems virtualization can solve. Areas such as business continuity (disaster recovery and high availability) and on-demand servers (for development and testing) are starting to get more attention in the marketplace, from end users as well as third-party software manufacturers. These solutions are going to continue to get more and more inventive.
