A Guide to Cloud Computing

Interesting article.

Everyone agreed that cloud services such as Amazon Web Services, Google Apps, and Salesforce.com CRM have become bona fide enterprise options, but there were also questions about privacy, data security, industry standards, vendor lock-in, and high-performing apps that have yet to be vaporized as cloud services. (For a recap of that give and take, see "Customers Fire A Few Shots At Cloud Computing")

If we learned anything from our Enterprise 2.0 cloud forum, it's that IT departments need to know more. Our approach here is to look at cloud computing from the points of view of eight leading vendors. In doing so, we're leaving out dozens of companies that have a role to play, but what we lack in breadth, we hope to compensate for in depth.

And this analysis is just the beginning of expanded editorial coverage by InformationWeek on cloud computing. Visit our just-launched Cloud Computing blog on InformationWeek.com, and sign up for our new weekly newsletter, Cloud Computing Report. We're also developing video content, an in-depth InformationWeek Analytics report, and a live events series in the fall.

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...
