Data Virtualization Technology Advancements

As a follower of Virtualization technology, you have likely heard about the June 2011 Forrester Research report on Data Virtualization entitled Data Virtualization Reaches Critical Mass: Technology Advancements, New Patterns, And Customer Successes Make This Enterprise Technology Both A Short- And Long-Term Solution.

University of Nebraska moves from Lotus to Office 365

The University of Nebraska has been using Lotus Notes since 1997, across five campuses. And in 1997 Lotus would have been a good choice. Perhaps less so in 2011. Microsoft, in an effort to get some big enterprise names across sectors into its cloud offering, is going to shift all of the five campuses to Office 365 for $250,000. A huge cost savings for UN.

Cloud efficiencies for utilization and DCs

There is strong evidence out there that large to medium datacenters are running at 7-10x lower efficiencies than the large service centers being run by the likes of Amazon or Google. James Hamilton gave a [talk](http://mvdirona.com/jrh/work ) on this topic, with [slides](http://mvdirona.com/jrh/work) about the real costs and the innovations happening circa 2010.

Critique of Cloud Computing

[Here](http://thingsthatshouldbeeasy.blogspot.com/2009/10/stormy-skies-for-cloud-computing.html) is an old, but thoughtful post on some of the shortcomings of a hybrid/public cloud provision by Eugene Rosenfield. His main points of criticism are issues surrounding:

1. SSO – In most cases, this is going to break any SSO you have with your internal users if they are using something direct in Windows.
2. WAN vs LAN – bandwidth and reliability. WAN costs are something people won’t be thinking of, most of them thinking at LAN speeds.
3. System integration – Not certain that I agree with Eugene’s critique here. He claims that the services to be integrated are external to your network boundary increases the integration complexity. Why should any integration call be more or less difficult than any other depending on URL length (i need a FQDN for something external, perhaps) or hops?

Anyway, worth a parse. Thanks, Eugene.

Cloud characteristics

In the modern enterprise there is a tension. Too many senior executives are hearing hype about clouds, and think they need to jump. But, if you stand back, you will see that we have been running private clouds in small versions since virtualized data centers came into existence. VMware and Citrix, etc., paved the technological road to running a (slightly more) elastic compute and storage environment than the days of all real iron. Then there was the move to public, with large providers leveraging their own, huge, data centers to offer externals to soak up extra capacity at a profitable price. But there should be concerns before you drop everything internal and run to the public cloud. That said, there are uses for it, and in fact you will be using it today no matter what. That is where *hybrid* comes in. Continue reading Cloud characteristics

IT Empire Balkanizaiton

Brian Hopkin’s posed an interesting (http://blogs.forrester.com/brian_hopkins/11-06-03-what_happens_when_central_it_no_longer_exists) on what would happen when there was no longer a central IT shop for an organization. It stirred up the responses, as one would expect. I, for one, fall into the camp that the cloud *will not* remove the need for IT within any organizaiton, especially larger ones. However, the cloud will contribute to the mindset that silos *can* effectively control their destinies and spin away from the central authority. Continue reading IT Empire Balkanizaiton
