VMware ESX still leads the market, XenServer grows almost 300%, Hyper-V grows over 200% says IDC
(from Virtualization.info) – Last week IDC published its Worldwide Quarterly Server Virtualization Tracker for Q4 2009, reporting an increase in the amount of servers used for virtualization.
18.2% of all new servers shipped in the last quarter of last year in fact were virtualized, compared to 15.2% in the same period of 2008. Despite that, the total amount of virtualized servers in 2009 was 5% less than in 2008, with a 14% decline in spending for virtualization hosts.
Virtualization software revenue didn’t go much better:
Worldwide virtualization software revenue for all CPU types declined 10% year over year in 4Q09 to $447 million, thanks primarily to economic pressures and an increasingly competitive marketplace. Virtualization licenses increased 13% year over year and 21% sequentially in the quarter but declined 7% for all of 2009.
HP continues to lead the market with 38% of all virtualization hosts shipments, followed by Dell and IBM. IBM was the only vendor with positive growth in 2009, increasing 1%.
The most interesting news anyway is about the hypervisors market share (our emphasis):
VMware ESX continues to be the number 1 virtualization platform with total licenses increasing 19% year over year in 4Q09. – VMware Server continues to be the number 2 virtualization platform despite declining 9% year over year. Microsoft Hyper-V continued its ascent, capturing the third highest market share by growing 215% year over year, albeit off a small base. Meanwhile, Virtual Server 2005, with the fourth largest share, continued its depreciation with year-over-year licenses declining 29%. Citrix XenServer also showed impressive year-over-year growth of 290% and rounded out the top 5, coming off its third quarter of offering the product for free with certain management functionality. XenServer’s sequential growth was a relatively modest 25%…

Real-World Security in a Virtual Infrastructure – Part 7
(from Virtualization.info) Network stability is a concept most system administrator instinctively know about: however, no organization actually had any need to willingly enforce it or even care about until recent years.
It’s only with the huge rise of mobile devices and their penetration inside enterprise environments that network – or better, infrastructure – stability has indeed become an issue.
What do we mean with infrastructure stability?
Stability is a property of any system behaving in a consistent, somehow foreseeable way. Most things in the world are somehow stable: you are not expecting your house to fall on your head, nor the hole in the wall you spent your Sunday fixing to pop open once again.
Just the same is true in networks, especially large networks. While new systems are being added on a rather regular basis, the vast majority of the infrastructure components keep running consistently until they stop serving their intended purposes and are then stopped forever. (…)
Social networks teeming with spam and malware
The dirty Web is getting dirtier. Today 95 per cent of user comments in blogs, chat rooms, message boards and other social forums are actually spam or links to malware, research shows.
Nearly 95 per cent of user comments in blogs, chat rooms, message boards and other social forums are actually spam or links to malware, according to a recent report from Websense Inc., a Web security software developer in San Diego, Calif.
What’s more, security tools provided by sites such as YouTube and BlogSpot are only 25 to 35 per cent effective in protecting Web users from “objectionable content and security risks,” noted Carl Mercier, director of software development at Websense. (…)
Forrester: IT spending in U.S. to jump 6.6 percent in 2010; Will the optimism stick?
Declaring the tech downturn history, Forrester Research came out with a rather optimistic view of IT spending in the U.S.
According to Forrester projections, IT spending in the U.S. will grow 6.6 percent in 2010 to $568 billion. In 2009, IT spending fell 8.2 percent. Projections for IT spending in 2010 have been moving gradually higher.
The global outlook goes like this: IT spending will grow 8.1 percent in 2010 to top $1.6 trillion. In 2009, global IT spending fell 8.9 percent.
Software and hardware will garner most of the investment as companies start a “new multi-year cycle of technology investment growth.” Forrester predicts a 7-year buying cycle led by analytics. These smart computing efforts will have technologies such as service oriented architecture, virtualization and cloud computing as pillars. (…)
