10 recession-proof IT skills

These companies employ a professional data center with hot skills "For people with the right skills and right attitude, this is a fantastic time to be in the data center space," said Dwight Gibbs, senior vice president of technology at Input, a Reston, Va., market intelligence firm.
Company data center has become the focus of the company. If you want in, here are the skills you need to have:

1. Virtualization.
A basic technology for the state of art-of-the-IT infrastructure, virtualization skills almost goes without saying.
Rick King, CTO at Thomson Reuters, the law, in Eagan, Minnesota, Put it this way: "Today the people who have spent much time with virtualization technology can pretty much work where they want - and that will be valid for a certain period , until nearly all data centers run almost everything in the virtual environment. "

2. Management services.
As the company's switch to cloud the use of public or private service provider, data center personnel need to ratchet up service management skills, said John Ryan, executive global portfolio is responsible for platforms and end-user services in technology consulting firm CSC.
"It's no longer enough to know how to manage the hypervisor and engaged in infrastructure workloads. People should turn their thoughts into an environment where capacity and demand management come together. They must be skilled in service management," he explains.
Joanne Kossuth, CIO and vice president of operations for the Franklin W. Olin College of Engineering in Needham, Mass., agrees. "Things like software and infrastructure as existing services, and adopted some higher than others. But five years into the future, it really will be about a combination of things and those data centers that will manage all .

3. Unified computing.
"Today the trend, as it will for the next three to five years, will unite computing - see the company's Cisco Unified Computing System, HP BladeSystem and IBM Matrix with a cloud computing strategy," said Rockwell Bonecutter, technology, data center and led the operation to North America at Accenture, a technology services consulting firm."Natural assumption you can get from it that this will be a hot button for new skills."
Thus, like any data center personnel have to get up to speed compute unified, principles and concepts of architecture, he said. As a result, we will have a data center run by people who understand how to provide business value and service rather than just knowing how to add processing power or storage, for example.

4. Green IT.
Going green is the mandate of companies around the world, and that leaves many IT organizations decide whether they need a point person for green efforts in the data center, King said. "This professional will focus on how to use green technology - as well as steering away from distributing non-tech green technology hijau.Karena often improve operational efficiency, such people will actually pay for themselves again and again," he added.

5. Resource management.
Along the same lines, the ability to finesse the conversation between IT and facilities become a critical skill in data centers, said David Cappuccio, managing vice president and head of research for Gartner's infrastructure team. "Building the capacity of the plan if you do not take into account energy consumption and heat dissipation is a program in a vacuum," he added. "You need a staff person who can really keep track of these things, speak the language facilities and translate it back into IT." These skills are sometimes packaged in a position called a resource manager or a liaison facility, Cappuccio said.
At Citigroup, they are wrapped into a position called critical data center planning and systems engineer, said Jim Carney, executive vice president of planning for data center services company based in New York global finance.
In fact, Carney says, "There is no data center manager I would never be able to hire blind to the side of the business because it is an integral facility uptime them."

6. Engineering.
At PricewaterhouseCoopers, "hottest skills and those most difficult to find the mechanical and electrical engineers who have a decent knowledge of technology and knowledge of current equipment and systems," said Rick Ancona, U.S. deputy CIO and CTO at PwC, a company professional services with U.S. headquarters in New York.
"If you build a data center even three or four years ago versus today, you are using a very different concept. Even with virtualization, it's really about power and cooling expenses. That is the complexity of the techniques that have denser servers introduced," he added.

7. Network.
Lights-out, remote data center worked only because the technology network, Citigroup Carney said. Which puts a premium on networking skills. "Data center managers need to be aware of the network - network configuration, hardware and vulnerability," he said."We need people who have skills are really good network or background tissue."
PwC, also, want people who have a network of skills such as building out data center strategy, Ancona said.
In particular, is looking for people on the monitor network operations center and space response, that "key positions that help ensure the availability of the overall environment and maximize uptime," said John Regan, director of data center services to PwC ..

8. Financial analysis.
As a hiring manager, Input's Gibbs says he considers one of the hottest financial analysis skills to a professional data center. "I need somebody who can determine the economics and technology applications based on business economics," he said.
In other words, if the application does not require super high availability, a professional data center should be able to crunch numbers to see if that could come out in the cloud or to live in special hardware in the data center, Gibbs said. "Quickly became a central data center business," he added. "So, if you do not understand the business, then you will not be working for a business center for a long time."

9. Project management.
In a similar vein, the need for strong project management and business analysis skills are taking, said Dave Willmer, executive director of Robert Half Technology, a company's IT staff TI.Dengan 2010 approved budget, the company began to invest in data center project, he said.
"I do not want to make it sound like a door blew off and this is the end to recession, but we see an increase in demand for business analysts and project managers to full-time positions as well as on a project basis," Willmer said.

10. Communication.
Good people skills can not be underestimated, says people in the data center. "When I think of a strong data center managers, communication and people management skills are way up there," said Jill Eckhaus, president Afcom, an association for data center professionals. "The world is changing the data center at a fast speed, and able to manage that means maintaining a structured environment. And that requires communication."
Good people skills are important, agree PwC's Regan. Even if professionals do not communicate the data center business, he said, there are a large number of communications needed in the IT organization.
With so many data centers to hone skills, it's time for opportunistic IT professionals, said Andreas Antonopoulos, senior vice president of Nemertes Research.
"So for those out of work, one thing to consider is taking a new direction and really focus on interesting things happening in IT," he said. "That's my message of hope."

Tricks to be a Network Administrator

Many people are asking, including me, what should be studied first when they want to learn networking? Of the few references that I read, all you have ahold of is:

1. Basic Networking Hardware What should be studied? Because of the core is where the journey packet to be sent from our computer to the server. What is a Switch, Hub, Router, Access Point, etc.. Taukah you that the switch is better than HUB. When do I use a HUB, Switch or Router. All must be accounted for properly. Where did we learn?, Many books can you meet who study it.

2. Basic IP and Subnetting Maybe if I say, this is a sangaat important of all, IP and subnetting. This will be felt if you work at an ISP. You will learn how IP efficiency, what is a gateway, How to manage IP well to prevent it from occurring Broadcasting and Coalision data.

3. Switching and Routing Technology If you already have more than 1 network, for example at your office, you should be able to perform routing of the network. You know, that the Internet can connect to everywhere because this routing. For switching VLAN you need to learn technology.

4. Technology Server If this one you'll be a lot to do with LDAP Server, DHCP, DNS, Etc.. The point is to provide services needed for the client. To find information please ask the help of Google. Type the server service you want to study.

5. Security Now once it has formed a good infrastructure server and then you notice the Security ranging from server to client.

6. Monitoring The monitoring covers all the good things of the infrastructure as well as from the software side. The better monitoring it, you will more easily control your network.

7. Backups This is often overlooked by the Network Administrator. Make a backup part or in full to anticipate Crash. Many technologies that could be done, one using Norton Ghost.

Where can I learn these things:
1. Of course the internet.
2. Book or Ebook.
3. Tutorial DVD.
4. Etc.

Hopefully useful.

View

Based on our analysis of the hardware industry, we expect the following developmentsfor the coming years:

* The number of hardware companies in Asia Top Hardware 100 will rise further,especially the number of companies from China and South Korea.
* Apple will continue the success and move into some more positions on the list,driven by the introduction IPAD
* Samsung, RIM, Huawei Brocade and tend to raise more revenue, given the strong market position and positive momentum in recent years
* As the economy recovers, most hardware companies will return to revenue growth
* Average revenue growth will rise from -8% to +5% (estimate)

Overall, we expect the computer and communications hardware industry will continue togrow faster than the world economy, on multiple levels. Investors beware: recession willhit on a double impact as well, as we saw last year.
