Now that we are a couple of years into the great cloud journey is it pretty
clear that the big bang theory of cloud conversion is ain't happening.
Yes, ISVs are moving rapidly to the SaaS model and it would be hard to find a
software startup who is *not* starting in the cloud, but enterprise adoption
of the public cloud is happening at a more stately pace.
In large part this is due to the simplification required to make public
clouds efficient and the complexity that characterizes most enterprise IT
environments. To put it differently, the public cloud makes app deployment
simple by pruning app deployment options to the point that few enterprise
applications can fit.
Moving forward, I see two paths for cloud adoption: evolutionary and
Revolutionary cloud: Public clouds like Amazon EC2 and CloudFoundry.com
represents a revolutionary leap forward for com... (more)

For cloud computing to take off, there need to be tools available that enable
a developer to build and deploy an application without having to download
anything to their desktop. This requires an on-demand development tool that
sits on top of the cloud and provides a development Platform as a Service
There are two paths that a vendor can take to create a development platform
for cloud computing: cloud-first or tool-first.
Cloud-first approach to PaaS: first build a cloud platform, then build a
development tool that runs on top of it. This is... (more)
Larry Ellison recently unleashed a tub-thumping tirade against cloud
computing covered by Ben Worthen (with further comments from Daya Baran, Giva
Perry and Dan Farber) . Here is a quote from Larry:
The interesting thing about cloud computing is that we've redefined cloud
computing to include everything that we already do. I can't think of anything
that isn't cloud computing... The computer industry is the only industry that
is more fashion-driven than women's fashion.
Now as usual with big whoppers told by people in fear of their checkbooks,
Larry's rant has an element of truth.... (more)
When virtualization took the data center, it offered huge cost savings for IT
ops and zero migration pain for developers. Coming at a time when IT was
being pressed by the business for savings, vSphere took the data center by
This example is instructive when trying to consider why private cloud has had
a slower adoption. The short answer is that cloud offers fuzzier benefits for
IT ops while forcing a lot of pain on developers.
The lack of a smooth migration path for existing workloads to the cloud goes
a long way to explain the relatively bumpy growth of the private cloud... (more)
Thomas Bitman of Gartner wrote a blog post last year about why OpenStack
projects fail. In that article, he outlined three particular metrics which
together cause 60% of OpenStack projects to fall short of expectations:
Wrong people (31% of failures): a successful cloud needs commitment both from
the operations team as well as from "anchor" tenants. Wrong processes (19% of
failures): a successful cloud automates across silos in the software
development lifecycle, not just within silos. Wrong metrics (10% of
failures): a successful cloud focuses on top line transformation by
