What cloud computing really means
Cloud computing is all the rage. “It’s become the phrase du jour,” says Gartner senior analyst Ben Pring, echoing many of his peers. The problem is that (as with Web 2.0) everyone seems to have a different definition.
As a metaphor for the Internet, “the cloud” is a familiar cliché, but when combined with “computing,” the meaning gets bigger and fuzzier. Some analysts and vendors define cloud computing narrowly as an updated version of utility computing: basically virtual servers available over the Internet. Others go very broad, arguing anything you consume outside the firewall is “in the cloud,” including conventional outsourcing. Read more of this article »
Autodiscover and Multitenant Hosting
In a corporate environment, Microsoft Office Outlook 2007 clients locate an Autodiscover service running on a Client Access Server by directly querying the Active Directory directory service and locating relevant Service Connection Points (SCPs). This is shown in the following diagram:
Figure: Using Outlook 2007 to locate an Autodiscover service
For Internet users, Outlook 2007 will attempt to locate and connect to an Autodiscover service based on the e-mail domain of the user. For example, for the user johnc@alpineskihouse.com, Outlook 2007 will automatically try to connect to the following URLs in turn: Read more of this article »
Cloud-hosted collaboration Multi-Tenant or Dedicated?
We just had another of our regular cloud research meetings at Forrester. In these meetings, we cut across our research organization to examine cloud computing from every angle.
Compared with even just a year ago, it’s amazing how important and pervasive cloud computing analysis (as opposed to cloud computing guesswork) has become in our research calendar.
You can see the existing cloud/SaaS research here and our planned research here. As the meeting host, I mostly listen, probe, and take notes, but ocassionally I get to jump in with a thought. Read more of this article »
Mind-reading computers
Huge crowds at the CeBIT fair gathered round a man sitting at a pinball table, wearing a cap covered in electrodes attached to his head, who controlled the flippers with great proficiency without using hands.
“He thinks, left hand or right hand and the electrodes monitor the brain waves associated with that thought, send the information to a computer, which then moves the flippers,” said Michael Tangermann, from the Berlin Brain Computer Interface.
But the technology is much more than a fun gadget, it could one day save your life.
Scientists are researching ways to monitor motorists’ brain waves to improve reaction times in a crash.
In an emergency stop situation, the brain activity kicks in on average around 200 milliseconds before even an alert driver can hit the brake. Read the whole story.
Microsoft releases virtualization drivers

Last week, Microsoft released a set of drivers that allow production versions of Red Hat to run on Hyper-V. The drivers, otherwise known as integration components, have some limitations, but they come with the full assurance that both Microsoft and Red Hat will support such an implementation.
Specifically the drivers support RHEL 5.2, 5.3, and 5.4. These drivers also support SUSE Linux Enterprise Server 10 SP2 x86 and x64, and SUSE Linux Enterprise Server 11 x86 and x64, but that’s old news.
With much fanfare, Microsoft first submitted said drivers to the Linux kernel way back in July (its first, and so far only, contribution to Linux, for obvious reason). Those drivers were already tested to work with Red Hat and, of course, SUSE. And in October, Red Hat and Microsoft announced that they were joining each other’s virtualization partnership programs, and validated that their products worked on each other’s virtual machines. So what took Microsoft so long to release these Red Hat drivers to the public? Read more of this article »
Oracle virtualization portfolio got a boost
The Oracle virtualization portfolio got a boost with Oracle’s $7.4 billion Sun Microsystems acquisition, and the company has signaled a willingness to take on VMware, the market leader. Many are skeptical, based on Oracle’s very late push into the market.
But even some of these skeptics acknowledge that Oracle VM 3, expected this spring, will give Oracle credible Xen-based server virtualization that could challenge VMware, Microsoft and Citrix Systems Inc.– at least in the tens of thousands of Oracle database and application shops.

Hardware or OS virtualization
Server virtualization Running applications in separate, isolated partitions within a single server. The “virtual machine” method can run different operating systems simultaneously, whereas the “OS virtualization” method runs applications for only one operating system (see virtual machine and OS has recently been gaining greater attention by enterprise IT professionals. There’s a good chance that you have come across someone using, promoting or writing about the wares We love “wares” in this industry as noted below. Read more of this article »
Novell would be wise to embrace Xen
Novell would be wise to embrace Xen and KVM — but only if the company has adequate resources to support both sets of customers.
The Waltham, Mass. company is the second biggest Linux distributor and supporting both open source hypervisors would give it a significant differentiator over its key rival, Red Hat, which announced that it will back KVM as its strategic hypervisor over the long haul. Read more of this article »
Turn your ARM into a touchscreen display !
Those who find the touchscreens on their ever shrinking gadgets too fiddly to handle, will be glad to hear scientists are developing a new touch surface… your own arm.
Developers at Microsoft Research and Carnegie Mellon University are working together to create an armband that projects an interface directly onto your skin.
They have combined a mini projector which creates a changing display with a sophisticated sensor that can tell which part of your arm is being tapped.
