Cloud Computing is the most discussed IT innovation of recent times. This
Primer provides a structured overview of what Cloud Computing is and what the
potential benefits and risks are. In addition it explores how Cloud Computing
will impact IT management and IT's role in the organization as a service
It also looks at the risks of Cloud Computing. Risk is consistently cited by
CIOs and CFOs as the largest obstacle of cloud computing for their
organizations. In this primer we consider the risks in areas such as
availability, privacy and regulatory compliance. The booklet explores some of
the reasons why organizations want to implement Cloud Computing, to name just
a few: cost-savings, increased speed and flexibility and higher performance.
It looks at how the Cloud delivers against these expectations and debates its
long term viability.

With security and legal concerns being slowly addressed by the industry,
lock-in and standards are rapidly becoming the biggest concerns regarding
cloud computing. If the cloud industry is to make good on its promise, these
will need to somehow be addressed. Let’s examine some recent developments.
Interesting to see how, just a week after my blog on “The Principles and
Perils of Vendor Lock-in” *1 several vendors made announcements seemingly
supporting my suggested approach. For example, after hinting at the potential
benefit of decoupling SaaS and PaaS from its underlying Infrast... (more)
It seems like every week another sizing of the cloud market is published, and
– maybe as to be expected - none of them seem to agree.
Let’s have a look at who is saying what, and whether we are comparing
apples to apples, or apples and oranges.
We will start by looking at SaaS. The most recent numbers from IDC claim that
SaaS revenue will grow 5 times faster than traditional packaged software.
This would mean little if traditional packaged software is expected to no
longer grow (five times zero would still be zero). Joe McKendrick at ZDNet
took IDC’s numbers and extrapolated from t... (more)
Cloud computing can be seen as an important enabler for more user and
business empowerment. Traditionally we consideredany IT outside the IT
department’s purview“Rogue IT” or “Shadow IT”. In this blog we
examine how further user empowerment may impact the future of corporate IT.
Rogue IT (sometimes called shadow IT or consumerism) is the phenomena in
which employees outside the IT department deploy IT technology to achieve or
automate certain tasks. Rogue IT is not a new phenomenon. But cloud computing
is giving it a new runway and much better camouflage, since with cloud
In my last post I covered the concept of fabric computing and why it matters
in the world of cloud computing. With a "fabric" approach towards creating
a cloud application, we include the virtual compute, storage and network
components inside a fully software-based model of the service. This is
distinctly different from a more traditional approach, where the various
resources are added and configured one by one.
In response to a comment, I also suggested that this new approach could be
compared to a modern espresso machine. Such a machine delivers a complete
service (coffee!) -... (more)
In the past weeks we launched directly from the season of cloud events into
what SYS-CON calls the Annual Predictions Bonanza. Gartner released its
predictions on December 1 leading with "critical infrastructure will be
disrupted by online sabotage." At CIO magazine Bernard Golden gave two
interesting points of view, one for vendors and one for users, and even CA
Technologies offered insights into the changes we expect in 2011, including
how "security will shift from being perceived as a cloud inhibitor to
becoming a cloud enabler."
So, what happens after 2011? In a few upcomi... (more)
