Mission Critical Applications not ready for Virtualization, says RackSpace

Really? First I'd like to know what do you really define a mission critical application? A simple email server for an e-commerce firm is "heavily-mission critical" and all those "mission critical" apps are already running on the hypervisor.

It is premature for hosting providers to offer virtual servers and it is unlikely that virtualisation will save its users money, according to survey research conducted by Rackspace Managed Hosting, a recognised leader in the global managed hosting market.

These were two major points arising from more than 300 responses to an e-mail survey of Rackspace customers, in which 87% of those who responded confirmed they would not share a server with other hosting customers.

Most of them also confirmed they believe virtualisation is not ready for mission-critical applications.

"Perhaps companies that have already started offering virtual hosting have jumped the gun," says Rackspace spokesman for the South African market, Geoff Dowell.

"Virtual servers appear to have only limited application in hosting, and perhaps this is because although it is a maturing technology it is also a highly complex one. It allows businesses to consolidate infrastructures consisting of hundreds of servers down to 25 or so, but the management and administration is extremely complicated because the management tools behind the technology are immature."

I don't know what potion do the folks in Johannesburg are sipping, but elsewhere in Africa, we are going to host a couple of clients on a single central data center. All mission critical! Read the rest.


  1. So you ask customers that chose a dedicated hosting plan if they are willing to share?
    Why don't you ask customers of shared hosting plans (multiple instances..) if they are willing to use virtual machines?

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…
