Virtualization and cloud computing are essential features of the datacenter

Greschler, director of Microsoft's integrated virtualization strategy, says that virtualization needs to be a necessary feature of the datacenter for tactical and strategic reasons-server consolidation, saving energy, migrating data between devices and even data centers.

Virtualization is a necessary feature of the datacenter

Microsoft integrates virtualization technology into its own operating system, making hyper-V a component of Windows Server 2008. Microsoft offers a free hypervisor--hyper-v Server 2008.

Matt Lavallee, technical director of the UK Shremls property information Receptacle (PIN) multi-protocol services company, says Microsoft's integration strategy can be of great benefit to them.

"Our capacity is growing rapidly, so we know that virtualization is the solution," he said. This would be a big problem if we didn't use Hyper-V. "

Especially important is the training section. "We initially conducted an early cost assessment of Hyper-V and VMware ESX servers with VirtualCenter," he said. If you use ESX, we have to increase the cost of training-if it is a new technology for your environment and you have a six-digit tool set, then you have to plan this training and knowledge. "In addition, VMware's solution requires 160000 of dollars, while Microsoft's Hyper-V is free, MLS pin has been licensed by Windows Server 2008, and it has no limits on node capacity."

The MLS pin has now streamlined 60 stand-alone servers to 20 clustered servers running Hyper-V. The next step is to virtualize the storage, followed by the network device.

For Microsoft, making virtualization ubiquitous slogans a reality also means managing the entire end-to-end. For a Microsoft System Center platform, this means being able to manage physical and virtual devices, including hypervisor from other vendors. "Hypervisor lays the groundwork for you, but it is management that gives you value," he said. "

Next, Microsoft will further enhance this flexibility and scalability, allowing businesses to migrate workloads between their own data centers or leased computing resources. "This will bring new challenges, including directory, compliance, security and configuration--no one has a clear answer now, either Microsoft or VMware," he said. "

But Microsoft is committed to this kind of IT service model, not only from Hyper-V and System Center, but also from Microsoft's cloud products--azure.

Cloud computing changes the original role of the data center

"If you are an IT manager, cloud computing will fundamentally change your job responsibilities," said Hal Stern, head of engineering at Sun Corp., in a Wednesday conference on technology Management at the security Industry and Financial Markets Association.

"With the advent of cloud services, we are moving away from the world of hardware," Stern said.

He means that the system administrator will monitor the network rather than the hardware components. "We still need systems administrators, but we no longer need them to be busy around the data center with all kinds of hardware tools," Stern said. Instead, they will use remote sensing surveys and tools to assess system capabilities, safety and performance.

But what is the cloud? The cloud has five attributes, according to the Gartner consulting firm. It is service based, upgradeable and resilient, adding and removing infrastructure as required. The cloud uses shared infrastructure to achieve economic savings resulting from the expansion of the business scale. The cloud is measurable and can be paid by the user as usual. Of course, the most important thing is that the cloud uses Internet technology.

Some companies do not want to share infrastructure, so they build so-called private clouds. Other users are concerned about the price and will share the cloud infrastructure with other companies on the cheaper public cloud.

"There are many kinds of clouds in sun's view," Stern says. A private cloud, a public cloud, and a cloud between the two.

Pressure between research and development personnel and staffing

For IT managers, especially system administrators, cloud computing can solve some of the most troubling challenges. "Cloud computing can help address the tension between developers and Configurator," Stern said. This tension has existed since the time of Eden. If Apple is not for developers, why is it there? "Stern's metaphor is to call IT administrators God."

Stern says "IT administrators ask" Why are users so urgent? How do I audit what they do? Why do they need so many versions? ' And so on. "

All this will be easier on the cloud. Application software can be monitored and configured better according to the needs of users.

"Emerging companies look at the cloud as a way of salaries systems where developers pay instead of paying for infrastructure," Stern stressed.

The cloud makes monitoring easier, but paying for demand is not always cheap, stern warns. If you drive a car every day, he says, you should buy one yourself, but if you only drive occasionally, you should use a lease.

Sometimes business executives use the cloud to circumvent it. Stern, the New York Times data architect Derek Gottfrid, illustrates this by using Amazon's elastic computing cloud and Hadoop parallel data processing architecture to turn the 70-Year-old newspaper into a timesmachine file.

"Note that what Gottfrid is doing is ultimately around the IT department," Stern said.

If you don't do it every day, Stern stressed, it makes sense to use the cloud to process this magnitude of data (810000 PNG pictures and 405,000 JavaScript files).
