CIOs are looking at Cloud Computing

What is Cloud Computing? Cloud computing allows you to access your data without understanding or being responsible for its infrastructure, depending on software as a service. A report published by leading analyst firm Gartner says that it’s a developing concept that combines Software as a Service, (SaaS), Web 2.0 and other recent Internet-based trends.
At its best, cloud computing allows you to outsource your infrastructure and get rid of your IT department. Many startups use it to avoid costs. But executives have also learned that mission-critical applications can sometimes go down. Prominent outages have recently occurred at Amazon and eBay.

Cloud computing is not the same as grid computing, which is simply a cluster of loosely connected computers that distribute tasks among themselves. The report, Market-Oriented Cloud Computing: Vision, Hype, and Reality for Delivering IT Services as Computing Utilities reports that many cloud computing deployments are today powered by grids, have autonomic characteristics and are billed like utilities. Cloud computing is a natural next step from grid computing. Some successful cloud architectures have little or no centralized infrastructure or billing systems whatsoever including peer-to-peer networks like BitTorrent and Skype and volunteer services like SETI.

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.

Splunk that!

Saw this advert on Slashdot and went on to look for it and found the tour pretty neat to look at. Check out the demo too! So why would I need it? WHY NOT? I'd say. As an organization grows , new services, new data comes by, new logs start accumulating on the servers and it becomes increasingly difficult to look at all those logs, leave alone that you'd have time to read them and who cares about analysis as the time to look for those log files already makes your day, isn't it? Well a solution like this is a cool option to have your sysadmins/operators look at ONE PLACE and thus you don't have your administrators lurking around in your physical servers and *accidentally* messing up things there. Go ahead and give it a shot by downloading it and testing it. I'll give it a shot myself! Ok so I went ahead and installed it. Do this... [root@tarrydev Software]# ./splunk-Server-1.0.1-linux-installer.bin to install and this (if you screw up) [root@tarrydev Software]# /op

Virtualization is hot and sexy!

If this does not convince you to virtualize, believe me, nothing will :-) As you will hear these gorgeous women mention VMware, Akkori, Pano Logic, Microsoft and VKernel. They forgot to mention rackspace ;-) virtualization girl video I'm convinced, aren't you? Check out their site as well!
