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
allocation size limits to the ways in which storage is managed. These are
just some of the things you’ll want to consider as you start to think about
integrating cloud computing into your existing IT environments.
I’d like to focus in detail on the complexity and variability of cloud

For cloud computing to gain traction in the enterprise, IT and security
executives need to be certain that their company’s applications and data
are safe. But when security is partly out of enterprise control, it becomes
impossible to know if sensitive information has been accessed or compromised.
Today, using a public cloud means moving from an internal environment where a
company has complete control of data and processes to an environment where
that control belongs to someone else, and is often opaque. Within the cloud,
applications run in a multi-tenant ... (more)
Recently, we’ve had a number of discussions with enterprises about how
they’d like to use the cloud. The basic use case is around capacity
on-demand (not surprisingly), but the specifics have raised some interesting
issues. The companies have distributed branch offices that need the capacity
for a range of applications, including dev/test environments as well as
back-office and web apps. Today, these distributed groups are relying on
corporate IT to meet their scaling and infrastructure needs, and they are
frequently bottlenecked. This is both in terms of overall challenges in
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... (more)
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)
