VMware, Citrix tell us why hypervisors are hot!

In that sense, their importance lies in the fact they break a stranglehold that Microsoft(MSFT) and other big system vendors have had on exclusive tie between the application and the chip. They open the door to new ways of handling processing tasks for an application, reducing the exclusive role of the operating system. Hypervisors might even allow replacing the operating system someday through a new intermediary, like the Java Virtual machine. But such changes are many years away, and operating systems as of today remain a key component inside the virtual machine itself.

Consider what Rosenblum said before his remark on operating system vulnerability. His main point was hypervisors displace -- not replace -- operating systems as the software that talks to the hardware.
Correct! OS administration has seen to rise at clients I have had contact with. Most of them have had to deal with a lot of OS administration, well not everything is OS administration , if you are moving VMs then it is a VM administration, if you are patching OS the same old fashioned way then its OS administration. But with tools like Shavlik, you will considerably reduce the OS and even Hypervisor (ESX or Xen) administration issues like patching etc.

So gradually robust security and process management will help us all also reduce OS administration, but I am not sure about the "time factor". Somehow virtualization suddenly gives an organization a feeling like we could do everything! You have several copies of OSes lyin around.

Anyways OS will be gradually displaced. Thats for sure! Read the rest.

What won't change

Links/Referrals: I will be redirecting the links (all links which you may have cross-posted) to IdeationCloud.com - so you don't have to do anything in all your posts and links. Although, I would urge however that you do change the permalinks, especially on your blogs etc yourselfThis blog is not going away anywhere but within a few months, I will consider discontinuing its usage. I won't obviously do …

Cloud Security: Eliminate humans from the "Information Supply Chain on the Web"

My upcoming article, part - 3 data center predictions for 2009, has a slideshot talking about the transition from the current age to the cloud computing age to eventually the ideation age- the age where you will have clouds that will emote but they will have no internal employees.

Biggest management disasters occur because internal folks are making a mess of the playground.

Om's blog is carrying an article about Cloud security and it is rather direct but also makes a lot of sense:

I don’t believe that clouds themselves will cause the security breaches and data theft they anticipate; in many ways, clouds will result in better security. Here’s why: Fewer humans –Most computer breaches are the result of human error; only 20-40 percent stem from technical malfunctions. Cloud operators that want to be profitable take humans out of the loop whenever possible.Better tools – Clouds can afford high-end data protection and security monitoring tools, as well as the experts to run them. I trust…
