2010, the Age for Virtualization

by Cecille Ramirez on April 5th, 2010

How important is virtualization? I read an article by Gartner Group telling us that virtualization will rule the I.T. world as early as 2010. It looks like it’s already here but are we using it? How do we benefit from it then?

Virtualization means software implementation of different services in one single physical box. It just means, IT departments need not invest anymore on several physical servers just to address different services.

Long time ago when I was still working in the MIS department of a bank, data is too critical that we have to plan well. Additionally speed is important for bank branches to make a request for certain data at their end. We’ve been talking about heavily of client/server setup then followed with the idea of business logic in the middle to handle requests before it goes to the back end servers to offload it from heavy failing requests.

Technology infrastructure has evolved so fast that these days the “in” thing is to go for virtualization. Whenever you hear someone from your tech group discussing about virtual machines then your company may have started with it already.

Windows 7 is ready for virtualization. It’s already built in. Other operating systems can accommodate installation and setup of client based virtualization like the free Virtual PC and the not so free VMWare. So what is exactly virtualization?

Virtualization will save a company lots of $$$ amount. Any services that are related can be hosted in one box; virtualization is possible as opposed to lots of physical servers to host each of these services. Long time ago, a computer serving as a print server, file server, at the same time a client computer will definitely crawl for it is handling all these services. The ideal setup as always is to have one physical server for one service.  Costly since we’re talking of three dedicated computers to provide the abovementioned. This scenario connotes the idea of N-tier setup where N could mean numerous or infinite number of machines to address the services need to be in placed in the company’s network.

These days, this is not the ideal setup anymore. Let’s go green by doing virtualization. With company’s trying to cut on electric bills, virtualization will definitely be the key thru consolidation of various services into a single server. Gartner says in many cases, a virtual machine running means one less physical machine in operation. Cool huh?!?!

Concern by many now is, are we saying HP, Dell and other known computer vendors will lose market for physical servers? Not really for as long as these IT vendor giants will start building heavy duty boxes to handle the load then they can still make money. So it’s a win-win scenario if in case.

For those who want to practice on virtualization, try to download the Virtual PC 2004 or 2007 from the Microsoft website, it’s free. The only thing that is not free of course are the software and operating system that will run inside that virtual machine box. If you just want to try it, trial versions of software you can get will also work in it.

A Cisco Success Story

I attended a resume writing seminar & conducted mock phone interviews with a Microtrain career counselor. These two activities gave me a leg up on distinguishing myself from all the other people looking for work. Since the career counselor's at Microtrain had a track record of getting people hired, their insight and positive past experiences helped me tremendously in getting hired with a Cisco Voice Systems Integrator in the Chicago area. I was hired as a Cisco Voice Tech Engineer with a starting salary of $65,000 / year with a Cisco voice systems reseller located in the Chicagoland area. Microtrain was very instramental in making this a reality. From expediting my WIA grant, to providing excellent hands-on training from knowledgable instructors I was able to achieve becoming certified with my CCNP. Microtrain's career services was the final catalyst in connecting me with this company by communicating with them on my behalf and with me in setting up the interview. One week later and I was hired. No joke. Thanks Microtrain!

The instructor [Al Khalfan] was very knowledgeable in the field. He presented the materials and concepts with a professional touch. He also frequently adds humor to his teachings, which made it easier for me to understand. The support staff was all nice, gentle, caring, and very helpful. The materials, rooms and amenities were excellent and exceeded expected standards.

Employer Partner Feedback

Dawn has been a pleasure to work with. She is diligent in her efforts to give MicroTrain’s students the best opportunities to connect and network with various companies and players in the job market. The curriculums and certification programs are in line with today’s current IT needs. It’s good to see that they evolve with what employers are most seeking out there. I would recommend to any employer that hires skilled IT workers that they look into MicroTrain’s career services department as a potential source of candidates. The business of hiring can be quite costly, and Dawn and her staff provide a free service to outside companies. This value-add for MicroTrain’s students aligns with their mission in both training and job assistance to set up a win/win scenario for all involved.
