This article discusses upcoming trends in hypervisors with a panel of experts to include Al Gillen, an analyst IDC who tracks virtualization developments, Kerry Kim, director of solutions marketing at SUSE, and Adam Jollans, program director of IBM's Linux and Open Virtualization Strategy.
A hypervisor, also called a virtual machine manager, is a program that allows multiple operating systems to share a single hardware host. The hypervisors controls the host processer and resources so that each operating system appears to have the resources individually.
One major issue discussed is the differences between proprietary and the open source hypervisors. Currently the pace of innovation is much faster with open source technologies. In addition, open source development allows for more service and support options. However, this rapid development isn’t always enticing to corporate information officers. Many are overwhelmed or even intimidated by it. As Kim puts it, “It's not because customers don't want innovation; they just can't really embrace the innovation as quickly as it comes.” Instead, they tend to stick with established relationships. Another benefit of sticking with the same vendor of their other components is that they will have a single stack of software.
Another concern with hypervisors is how they will interact with a cloud provider that has implemented a different type of hypervisor. Do to this concern most companies “support customer choice” by ensuring compatibility with “various third-party tools, whether they're open source or proprietary.” Many companies are leaning towards VMware because it has a reputation as having less of a platform agenda.
