And despite all of the hype surrounding the Oracle VM announcement, don't expect companies to start standardizing on Oracle VM just yet, said Mike Amble, an independent Oracle consultant and former Oracle database and business applications user with Fidelity Investments. Instead, Amble says he fully expects to see Oracle VM and VMware running side-by-side at his clients' organizations in the near future, even though most budget-minded folks would prefer to standardize on one or the other. "In the industry, what we're looking for to cut our costs is standardization. We've been trying to standardize forever. But the vendors don't like us to do that," Amble said. "They just continue to perpetuate this inability to standardize, but I guess that's certainly nothing new in the industry. It's been going on since the inception, and everybody does it." The consultant added that the release of Oracle VM didn't come as a major shock, simply because virtualization has become so incredibly important these days.
"When you think about data centers, they've just become terribly, terribly expensive," Amble said. "So the only logical process from a vendor's perspective is to allow you to jam more and more processing into a smaller space, because that allows you to grow." Oracle raised eyebrows at its annual OpenWorld conference last month when it took the wraps off its new Xen-based virtualization platform. But Oracle wasn't alone. Sun Microsystems also decided to enter the virtualization fray that day with a Xen-based platform of its own. Oracle's virtualization announcement, and conflicting statements about whether Oracle would support Oracle applications running in VMware virtual machines going forward, led to a great deal of speculation among IT industry analysts and technology users. As it stands now, Oracle says it doesn't officially support its apps running in VMware, but does so in practice. VMware won the latest battle in the virtualization war on Tuesday when German enterprise resource planning giant SAP AG announced plans to support all SAP business applications running on VMware's ESX Server software. Virtualization grows up The new virtualization platforms from Oracle and Sun are further proof that virtual machines are becoming part of the fabric of IT, according to Tony Iams, a senior analyst and vice president with Ideas International, of Port Chester, New York. "It's becoming apparent that virtualization is here to stay," he said. "And with the emergence of production-grade open source virtualization based on the Xen Hypervisor, you're now seeing a lot of alternatives [to the established virtualization players], and that really just means more choices for users." Oracle and Sun will be competing head-to-head with virtualization heavyweights like VMware and Microsoft. But they're also likely to spend a great deal of time and money marketing their platforms as a solid alternative to established open source virtualization providers. Iams said the stiffest competition there will come from Red Hat and Novell, which provide Xen-based virtualization capabilities along with their Linux distributions, and to a lesser extent, independent providers like Virtual Iron and Citrix. "But the critical player here is VMware," Iams said. "VMware showed that there is a very healthy business around virtual machine platforms, and so all of these other players are here to try and take away some of that business." It's hard to accurately predict how well these emerging open source virtualization systems will "play together," Iams said, but from an operational standpoint, don't expect much compatibility at all. "They really are all completely different products that will have to be managed separately," he said. Users should keep an eye on support issues Oracle's conflicting statements about supporting VMware users are symptomatic of a larger issue affecting virtualization technology users -- an issue that cuts across proprietary and open source lines. The problem, Iams said, is that independent software vendors (ISVs) like Oracle all have varying and sometimes confusing terms for which platforms they'll support and how they'll support them. "It's something that users really have to pay attention to," he said. "I haven't heard of any situations where virtualization breaks the software, but you may get performance problems and tuning issues that you're going to need help with from the ISV." Iams has, however, heard about situations where ISVs were less than helpful on support calls. For instance, he said, when there is a problem with the ISV software, the ISV will often demand that users prove the bug exists in the physical environment before they step up and support it in the virtual environment. "That's just a lot more work for the users to make sure that the application runs correctly," he said. "It's important to make sure that the ISV fully stands behind [its] software in a virtual environment."
