The world of clouds these days is full of definitions and
counter-definitions. There are many posts that try to define the concept of
cloud computing; many that try to distinguish utility computing, grid
computing and cloud computing; many that try to define public vs private
clouds; and many that dismisses the notion of private clouds.
John Foley, in his article “The Rise Of Enterprise-Class Cloud
Computing“, referred to private cloud as an oxymoron,
That’s an oxymoron since cloud computing, by definition, happens outside of
the corporate data center, but it’s the technology that’s important here,
not the semantics.
But by whose definition? The industry as a whole haven’t even been able to
nail down a concrete definition of cloud computing. Given that there’s no
concrete definition, then by definition, private cloud is not an oxymoron.
But I do ag... (more)
In the past month or so I have talked to a lot of people in the cloud
computing and virtualization space. Many of these folks are working at/on
startups that solves one of the many challenges for Enterprise cloud
computing. What are these challenges? I have tried to summarize them here (in
no particular order).
I’ve written extensively about the need for data governance in previous
posts. In essence, enterprises have a ton of sensitive data that requires
access monitoring and protection. Data (and information generated from the
data) is the life blood of many ent... (more)

Platform-as-a-Service (PaaS) is one of the buzzwords that’s mentioned often
in the cloud computing space. In short, PaaS is a platform for delivering
applications, similar to a pre-built system with hardware, OS and application
stack all built in. In the PaaS case, this system is hosted. All you have to
do is “upload” the application code and it should take care of the
executing and scaling of it.
A quick survey of the land (by no means comprehensive, I am also including
ONLY application platforms, not service-specific platforms such as DabbleDB)
At RSA 2009 there were a ton of conversations spun up around the topic of
security and compliance in the cloud. First, there were ~20 sessions on cloud
security and compliance. I was on one of the panels that focused on cloud
security and whether the cloud is secure enough for the enterprises. (Great
discussions there and huge thanks to Asheem Chandna of Greylock for
organizing it.) Then Cloud Security Alliance released its Guidance for
Critical Areas of Focus in Cloud Computing (my initial comments.)
If you look across all of the regulations and mandates out there, like SOX,
