I recently read a Bank of America Merrill Lynch report about cloud computing,
and they described private clouds as "old wine in a new bottle." I think they
The report points out that a typical private cloud set-up looks much the same
as the infrastructure components currently found in a corporate data center,
with virtualization added to the mix. While the virtualization provides
somewhat better server utilization, the elasticity and efficiency available
in the public cloud has private clouds beat by a mile.
In short, the term "private cloud" is usually just a buzzword for virtualized
internal environments that have been around for years. By replicating
existing data center architectures, they also recreate the same cost and
maintenance issues that cloud computing aims to alleviate.
Despite their limitations, there is still a lot of industry talk about
Welcome to our enterprise cloud computing blog where we'll share our
perspectives on cloud computing trends and best practices for the enterprise.
We're a team with extensive experience in IT software and systems (learn more
about us), and we're passionate about the opportunity that cloud computing
offers for fundamentally improving enterprise IT.
However, we believe that before the cloud can reach its potential, some
innovation needs to take place within the enterprise data center to make
cloud computing simple, secure and tightly integrated with existing IT
infrastructure. Our ... (more)
Many IT managers would love to move some of their applications out of the
enterprise data center and into the cloud. It's a chance to eliminate a whole
litany of costs and headaches: in capital equipment, in power and cooling, in
administration and maintenance. Instead, just pay as you go for the computing
power you need, and let someone else worry about managing the underlying
But moving from theory into practice is where things get complicated. It's
true that a new web application built from scratch for the cloud as a
standalone environment can be rolled out qu... (more)

In the most difficult economic climate in decades, CIOs are reevaluating
their strategies and looking for new ways to reduce data center costs and
overhead while improving responsiveness to business requirements. Cloud
computing has emerged as a much more agile and efficient approach than what
companies have done in the past: adding more compute, storage and networking
capacity or trying to get more out of what they already own.
Cloud computing did not emerge from a vacuum, but has its origins in three
technology "megatrends" that most CIOs are already fa... (more)
This post is part of a series examining the issues involved when moving
applications between internal data centers and public clouds.
The true challenges in storage and data management in the cloud result from
the diverse and often unfamiliar processes and infrastructures offered by the
cloud providers, including: new provisioning methods, storage properties,
data population and transfer, and systems for data management (snapshots,
clones, replication, backup). The cloud providers define the relationship
between servers and storage and often impose constraints on everything from ... (more)
