Gartner: Server virtualization now at 18% of server workload

How fast is the shift to server virtualization happening? According to Gartner, 18% of server workloads this year run on virtualized servers; that share will grow to 28% next year and reach almost half by 2012.

Large enterprises have driven server virtualization over the last four years or so, and VMware holds an 89% market share against a handful of competitors that include Microsoft, Citrix, Red Hat and others. There are about 5.8 million virtual machines (VM) believed to be in use today, said Gartner analyst Thomas Bittman, speaking on the topic Monday at Gartner's Symposium ITExpo 2009 attended by thousands of high-tech managers from around the world.

But growth is anticipated among the small-to-midsize businesses (SMB), and it's in this segment that Microsoft has a good chance to build a customer base. By 2012, VMware's share is expected to shrink to 65% but the base of VMs will have grown to 58 million, a 10-fold leap. By that time, Gartner believes, Microsoft will hold 27% share, Citrix 6%, Red Hat 2% and others about 1%.
Small enterprises will be "looking at a much more level playing field," Bittman said. He said each of the VM software providers have ways to distinguish themselves in both features and prices, but for many the big question will likely be, "Should I choose VMware or Microsoft?"

VMware, which can boast higher density and a mix of operating systems support and maturity in features, costs more than other offerings, such as Microsoft's HyperV. As it begins to release improved VM software, Microsoft seems poised to achieve growth in the SMB market, Gartner believes.

Bittman said the migration from physical servers to virtualized ones is also tied to the revolution in cloud computing, where enterprises will be considering various strategies from private clouds to public cloud services and a hybrid model. The choices for an in-house virtualization platform that enterprises make now and in the near future are likely to influence their cloud-computing choices, too, Bittman pointed out.

Virtualization is "not a commodity," Bittman noted. There's no commonality in the switching or management at this point, and mixing and matching among VM vendors is not a likely choice at this point. But he noted virtualization provides dynamic provisioning, potential for disaster-recovery support, as well server consolidation, and "it's becoming the default" for the enterprise over the next few years.

Gartner：虚拟化负载已占据服务器负载近二成

【CNW.com.cn专稿】服务器的虚拟化进程到底有多快？根据Gartner的统计，今年已有18%的服务器负载是在虚拟化服务器上跑的；这一份额明年将升至28%，2012年将接近50%。

大型企业推动服务器虚拟化已有4年之久，而VMware的市场份额已达到89%，远远领先于微软、Citrix、Red Hat和其他竞争对手。Gartner分析师Thomas Bittman称，目前在用的虚拟机数量大约有580万台。

在中小企业中间，虚拟机的数量也在增长，在这一市场，微软抓住了一个很好的机会，扩大了自己的客户基础。到2012年，VMware的份额预计将会缩减至65%，但虚拟机的数量则会增长10倍，达到5800万台。Gartner认为，到2012年，微软的市场份额预计会达到27%，Citrix 6%，Red Hat 2%，其余厂商1%。

Bittman称，从物理服务器向虚拟化服务器的迁移还与云计算的演进密切相关，企业将会考虑私有云、公用云以及混合云等不同的策略。从现在开始，企业对内部虚拟化平台所做的选择也将会影响到其对云计算的选择。

Bittman称，虚拟化提供了动态配置、潜在的灾难恢复支持以及服务器整合等功能，在未来的几年内，虚拟化“将会成为企业的缺省配置”。（波波编译）
