Private Clouds, Multitenancy and Control

Update: The Amazon VPC example I originally gave in this post was confusing and in fact possibly incorrect in some ways. I have removed it.

Recently I posted a video explaining how we at Cisco look at the differences between internal and external clouds, versus private and public clouds. In short, Cisco believes that internal and external clouds describe where the resources underlying the cloud service reside. CloudsPrivate and public clouds describe where the cloud is defined and governed. Both of these definitions are from the cloud service user’s perspective, which is the perspective we believe matters most when rationalizing cloud investments.

I highly recommend that you follow the link and view the video, as I did a much better job describing the topic there than I have words to in this post.

The post resulted in a well formed response that I thought was worth reviewing. (Two well formed responses, actually, but my response to the other will have to wait until a later day.)

The response was from my good friend Sam Charrington, VP of Product Management and Marketing at Appistry. In Sam’s post, he took issue with my focus on control as the core issue behind the private/public differential:

Build it Right the First Time

We’ve recently embarked on an logical extension of the Advanced Services we’ve been providing for efficiency assessments for the last 24 months.  Our Facilities Design Specification Service is uncovering some interesting new approaches to energy efficient data center design.  Since you only get a very finite window of opportunity to make changes to an environment like a data center, modeling is key.

We use 6sigma from Future Facilities for highly detailed thermal modeling and good old Visio for everything else.  However, we are using with great success an intermediary application, Google SketchUp. Hats off and many thanks to the Google crew for giving this incredibly powerful yet simple tool away.  While we do use the pro version, most of our customers can use the free version to simply convey design intent.  Say goodbye to whiteboards.

You may have already used it and most likely have seen the 3D buildings in Google Earth.

Cisco at the Intel Developer’s Forum

 

Intel Developer’s Forum kicks off next week, so if you will be there, swing by and chat with our folks at booth (#401).  As Kirk Skaugen points out, Cisco and Intel actually have a long-lasting relationship that goes back many years and we continue to collaborate closely in areas like UCS and virtualization.

At the booth, you can see demos of UCS, the Cisco Developers Network, and a collection of our smart folks if you want to pick their brains on a number of topics.  Outside of the booth, we have a couple of speaking sessions. Ed Bugnion will we presenting a keynote on “Designing the Next Generation Data Center” (Sep 22, 10:15am, Room 2003) and participating on a panel on the “Future of Cloud Computing” (Sep 22, 5:00pm, Room 2007).

Finally, the Cisco SmartGrid folks will also have a booth there–you can find out more about SmartGrid here.
