Hello Chuck,
We have heard about and experienced some of the "goodnesses" in Virtualization. I will appreciate if you can share some of the challenges faced by organizations in moving applications from bare metal servers to the Hypervisor (can be any of the commonly available VMs- ESX/HyperV/XenServer etc) and how they overcame them. I understand that this might be a non trivial task....might be useful..it is just that one feels more assured when one sees that there are "no free Lunches here" and this solution too has some very real issues.


Great article Chuck. No more NetApp fights finally.
It will be good to see a cloud management software from EMC more that encapsulates services. Today Control center suite is more focussed on storage and makes no real cloud presence.

EMC or NetApp or anyone should evolve some new concept to move desktops securely from one location to another. Something worth explaining that my desktop remains always on the web and I can access it with any Hardware anywhere in the world.

Desktop Freedom on the web! - Idea #1

Imagine you provide a kiosk at the airport to plug on to cloud desktops...Cool right. EMC can do it with VMware VDI's easily.

VMware for Mobile phones! - Idea #2

As EMC owns VMware, why not have a ESX mobile version where one can load multiple personality of windows mobile virtual phones? Or even allow VMotion from one mobile phone to another?

Things to think about for real world cloud.

I'm curious how private clouds are being defined for storage in particular. I don't see anything in this post about Atmos and I believe one of the greatest near-term opportunities is for private cloud storage. Object-based storage is the right technology for the cloud regardless of scale, IMHO. File systems simply don't provide enough context for files or content. Objects allow for rich, descriptive metadata to be stored with file data, and that can be persisted for the long-term as well as utilized for intelligent processing. My interest is in providing our five remote offices with a cloud storage infrastructure that simplifies consolidation of file-based data, which is really easy to manage and low cost. I have kicked the tires on object-based storage with one of the smaller players (Caringo) because I could download and eval for free. So far I've been impressed, however, I am interested in what EMC has to offer with Atmos as well. Your thoughts on this would be appreciated.

Hi Dan -- you bring up some excellent points.

There is no argument that object-based models that package metadata with information is extremely attractive.

I can rant on that one for a while, and have done so often.

The unfortunate problem is that we live in a world where the vast majority of applications expect a more traditional file or block model to find their bits. They don't know how to generate metadata, or how to use it.

Stepping back, the implication is clear: any cloud strategy that can't bring a sizable portion of legacy forward in some fashion is a complete non-starter.

I believe the trick will be to provide both models (traditional *and* object-based), and provide customers a few bridging and migration options as they move forward.

Besides, there's plenty of clever stuff you can do behind a file or block abstraction :-)

Was fun discussing and debating all the terms and taxonomy with you Chuck. Had a ball with that back at the beginning of the year.
