Virtualisation technology may mean customers buy less hardware, according to chief executive of storage giant EMC, Joe Tucci, but he believes he must continue to grow his VMware "gem" before competitors, such as Microsoft, take over the market.
The battle to control the virtualisation market has heated up with the launch of a white paper from VMware, which accuses Microsoft of anti-competitive practices.
Most talk about virtualisation these days centres on using server hardware more efficiently. But the technology also has the potential to ease another headache: software installation woes.
The virtualisation specialists are fighting back. Companies like VMware, and more recently XenSource, got their start with standalone virtualisation software -- but Linux sellers and Microsoft, unwilling to cede their influential position selling the foundational software of a computer, are trying to make virtualisation a feature of the operating system.
Following months of anticipation and some high-profile criticism, Oracle has changed the licensing model for its databases and middleware on multicore servers, bringing it a step closer in line with competitors.
Being green, in terms of IT and datacentres, only very superficially has anything to do with saving the environment. In reality it is about cold, hard cash and how to spend less of it.
Companies that offer virtualisation software are changing their business models and tweaking their software.
