Virtualization technologies is one of the most pronounced mantras within the last couple of months. One of the reasons is that It companies expect virtualization technologies to boost their productivity and to cut their cost for hardware and system management.
"If you look at what demand is out there and the cost savings you can achieve with [virtualization], that speaks volumes. That's why it still gets the budget dollars approved for it," says Brian Gabrielson for Computerworld (article titiled "Top 5 Virtualization Skills Enterprises Want Now"). Robert is a regional vice president of Robert Half Technology, the IT-recruiting division of Robert Half International (RHI).
RHI predicted in their latest IT Hiring and Skills report that 8% of IT companies will hire additional staff during the 2nd quarter of 2009, while 6% expect to lay off employees because of their shrinking IT budgets.
According to Gary Federico, technical recruitment manager at Advizex Technologies, a company that implements VMware virtualization technologies "consolidation is a key component of almost everything that's going on". He adds that a lot of currently opened IT positions that aren't 'virtualization' positions, have virtualization as a big component as a part of the job.
The Computer World lists 5 virtualization skills, that according to the magazine enterprises need.
Even if "experience" is not a skill, in virtualization it is just not possible to build and manage solid virtual infrastructures without having been involved in practice before.
Another key skill for today's IT specialist is their ability to understand an existing IT infrastructure and to be able to transform it into a stable, efficient and flexible virtual infrastructure. Experts in virtualization technologies and architectures have to have a deep understanding of both "the virtualization technology and the IT that is already in place in order to avoid bottlenecks and inefficient load-balancing schemes", says Gary Federico. He also adds that they also need to make resource sharing as efficient as possible and avoid bogging down the network with the data moving among virtual machines, virtual storage and the real infrastructure underneath.
They way IT business organize and manage their storage systems is crusial for their business operations and there is not infrastructure model which can succeed while "gumming up the storage arrangements". Federico explains that "virtualizing storage (via storage area networks, primarily) should make the interface between virtual servers and virtual storage simpler, but idiosyncracies in one can cause major problems in the other".
Before the release of Microsoft's Hyper-V it was enough for any virtualization expert to have a experience with VMware's and Parallels product. The release of Microsoft's Hyper-V in Windows Server 2008 however changed the market and now the virtualization technologies of VMware. Microsoft and Parallels will co-exist in data centers.
According to analysts to administrate virtual servers and virtualized infrastructures means more than just to make sure "the NICs don't fall out the back of the physical servers". The administrators of virtual servers and virtualized networks have to control server sprawl and must have good expertise in security, so they can keep the virtual servers safe even when "users or the app dev crew spawn off rogue VMs like butterflies in spring", suggests Computer World.
VMware presented a new virtualization products during its VMworld Europe 2009 conference in Cannes. Their names are vCenter Server Heartbeat and vShield. Both virtualization technologies bring it closer to supplying the data center operating system via its virtual machine management capabilities.
The company announced that the new name of "Virtual Center", its virtual machines provisioning and management server is now vCenter Server. In Cannes the virtualization producer presented vCenter Server Heartbeat, a software that enable IT engineers to monitor the central management server. VCenter Server Heartbeat works as automation solution which transfers operations to another physical server in the case of failure.
The new virtualization technology now makes possible for VMware to offer a greater guarantee of continuous operations, because it provides automated failover of the central VM management server.
VMware will sell VCenter Server Heartbeat for $4,995. The solution works in conjunction with vCenter Server, a product priced at $9,995.
The other data center product that VMware announced in the virtualization conference is vShield Zones. It is a virtual appliance for security which allows data center engineers to create logical zones with different levels of security based on groupings of virtual machines.
VMware executives explained that "instead of having to cordon off a group of Internet-facing servers with their own settings in a demilitarized zone, vShield allows a DMZ to be created among VMs that may be co-hosted on the same physical server with internal applications".
Using vShield, the enterprise users can segment applications based on their security needs and run them in a shared environment, covered by their zone's protections. The product will be released within the 3rd or 4th quarter of 2009. A beta release however is set to be released within a month or two.

The end of the year is always a good time for analysis. 2008 is a very important year for the development of web hosting industry. This year web hosting changed a lot because of the new emerging hosting markets. One of the fastest developing markets in hosting industry is VPS Hosting. We can definitely say that 2008 is the year of virtualization. See what journalists and bloggers say:
"With a little more than a week to go in 2008, I found my mind drifting to the events of this year -- at least those relevant to IT. It may seem obvious, but I think that we'll look at 2008 as the year that virtualization finally landed. After more than a decade of x86 virtualization, it's to the point now where it's not only a viable technology, but it's being adopted in every IT sector, from production to development, from small to large business", wrote Palu Venezia in an article in InfoWorld's welog titled "2008: Virtualization's big year".
According to Paul Venezia virtualization will provide the framework for the next generation of IT infrastructures. He says that 2008 was the year that became a firm conclusion, not a potential.
"Virtualization is reorganizing the IT industry. It underpins cloud computing by making it possible to separate the software from the hardware", this is the conclusion of made by the Virtualization Conference. According to conference website Amazon Web Services (AWS) is now the world's largest cloud-based virtualization system and is "literally changing the world of IT as we knew it".
According to IDC the virtualization market has been approximately $560 million in 2005. It is expected to grow to $2.7 billion in 2009. According to Gartner, virtualization will be the highest-impact trend which will change the IT infrastructure and operations through 2012.
The analysts expect data center virtualization to stay as the most important market segment, but they also say that application virtualization, storage virtualization, and virtualization for end users are growing very fast.
Virtualization and Cloud computing top the list of almost any survey made this year.
One of the events that is expected to summarize the trends in the virtualization market and to set goals for 2009 is the International Virtualization Conference & Expo.
The popular web media SYS-CON is holding it's 5th International Virtualization Conference & Expo in London on January 26- 27, 2009. "The conference will be looking at every flavor of virtualization" as it is written on tits website.
The leaders in the industry are expected to hold keynote on server virtualization, virtualization management tools and virtualized desktop infrastructure, para-virtualization, security and compliance issues, Green IT, cloud and data center file systems, distributed I/O resource management, database management in virtualized environments, secure mobile device virtualization, and resource management and load balancing issues for very large clusters of up to 100,000 nodes.
