Can Cloud Computing transform IT?

Nice overview and a bit of the history on Cloud Computing:

Increasingly, big firms are launching into "the cloud" to sell services, while small firms plug in, waving goodbye to the server hidden in the closet.

"The future is about having a platform in the cloud," Microsoft Chief Steve Ballmer said of the trend in a July e-mail to employees. The company has invested heavily in new products that will be announced in upcoming months.

About four years ago, Seattle-based Amazon.com Inc. began hatching a way to sell access to its complex computer systems. The company had already built up a robust infrastructure to support the world's largest online retail operation -- so why not let other businesses tap in?

Amazon launched its Web Services in 2006, and more than 400,000 developers have signed on to pay for services such as storage space, database access and computing power.

"Over the next decade you are going to see an incredible transformation, in my opinion," Amazon Chief Executive Jeff Bezos told shareholders earlier this year. "It doesn't really make sense for most companies to have their own data centers, just as it doesn't make sense for most companies to produce their own electric power."

Examples of businesses that rely on Amazon are Twitter and even The New York Times, which uses Amazon to partly host its "TimesMachine," the newspaper's archives, including full-page image scans of papers going back to the 1800s.

Amazon's price for Web services starts in the pennies -- to use its Elastic Compute Cloud, for instance, Amazon charges 10 cents per hour per server.

"We routinely send people monthly bills for 17 cents," Bezos said. "If you store a gigabyte of data for a month, we'll send you a bill for 15 cents."

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

OS Virtualization comparison: Parallels' Virtuozzo vs the rest

Virtuozzo's main differentiators versus hypervisors center on overhead, virtualization flexibility, administration and cost. Virtuozzo requires significantly less overhead than hypervisor solutions, generally in the range of 1% to 5% compared with 7% to 25% for most hypervisors, leaving more of the system available to run user workloads. Customers can also virtualize a wider range of applications using Virtuozzo, including transactional databases, which often suffer from performance problems when used with hypervisors. On the administration side, customers need to manage, maintain and secure just a single OS instance, while the hypervisor model requires customers to manage many OS instances. Of course, the hypervisor vendors have worked hard to automate much of this process, but it still requires more effort to manage and maintain multiple operating systems than a single instance. Finally, OS virtualization with Virtuozzo has a lower list price than the leading hypervisor for comme...
