Business Benefits of Server Virtualization
It is hard to say that the demand for specific IT skills is very high in an economy that finds its base and then settles there. Recruiters admit that amide layoffs and cuts in IT budgets in areas called “hot” can be “less cold than others.”

Virtualization skills – which is both cutting edge technology that can save companies a lot of money on data center costs – however, it seems that it has overcome this weak praise and has become hot.
“If you can meet demand and savings with [virtualization] that says a lot. That’s why budget dollars are still approved,” said Brian Gabrielson, regional vice president of Robert Half Technology, the IT department that recruits agents. Contractual and recruiting giant Robert Half International (RHI).
The latest quarterly RHI report on employment and IT skills in the IT market predicted that 8 percent of companies would employ additional IT staff this quarter, and 6 percent expect layoffs to adapt to IT budget cuts.
“If any of my kids were ready for college this year and interested in technology, I would pay attention to virtualization,” said Gary Federico, technical recruiting manager at Advizex Technologies, Inc., who specializes in virtualization-based VMware.
Virtualization, like application development, is a broad concept that covers all the specialties as there are specialties in IT, and no one is an expert at all or even more.
So what are five everyday things you need to do a good job?
It’s not a skill in itself, but IT professionals with reliable and hands-on experience building and managing virtual infrastructure are still rare.
“There are many people with their VCP certification,” says Federico.
Certified internet expert, where you have to pass both the test and the laboratory exam, does not guarantee much practical knowledge. ”
Virtualization can be so complex besides subtle that even tech-savvy recruiters like Federico (who has worked as a Hewlett-Packard solution technician for years) cannot scrutinize VCPs whose knowledge may not be what they claim. “I have to get them back and talk to my real technical experts,” says Federico. “You can say.”
The ability to understand the existing IT infrastructure and to plan a stable, efficient, and flexible virtual infrastructure is, according to Gabrielson, the main requirement of customers who carry out new installations or virtualization updates.
Architects need to understand both virtualization technology and existing IT technology to avoid bottlenecks and inefficient load sharing systems. They also need to make the sharing of resources as efficient as possible and prevent data from getting into the network between virtual machines, virtual storage, and the underlying infrastructure, Federico said.
“It’s a real trick,” he says.
“Every purchase we receive for virtualization has a storage component.”Because storage is an integral part of the data usage patterns in an organization, virtual or non-virtual IT infrastructure will not be successful while modifying storage placement.
Storage virtualization (primarily through storage area networks) requires simplification of the interface between virtual servers and virtual storage, but the peculiarities of one can cause significant problems for the other.
A year ago, this was enough to become a real expert in VMware virtualization software. It is also an essential component of the experience of a virtualization guru. However, the release of Microsoft Hyper-V in Windows Server 2008 has opened the door. Analysts such as Burton Group’s Chris Wolf predict that VMware and Hyper-V will need to coexist for long periods in the data center.
Virtualization “experts” who can manage one vendor’s technology but not another are likely to be practically only useful.
Being the system administrator for virtual servers or virtual machine virtual machines means more than making sure the network card does not fall behind the physical server. VM sys users must control server media and have adequate security capabilities to keep good servers even when users or members of developers create an excellent rogue espresso like a butterfly in the spring. The crop.
Gabrielson said, “Security has been a requirement for all the services available in the data center.” “In a moral sense, it’s more important because the right person does everything else.”
