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.

IT vendor lock-in is as old as the IT industry itself. Some may even argue
that lock-in is unavoidable when using any IT solution, regardless of whether
we use it “on premise” or “as a service”. To determine whether this
is the case, we examine traditional lock-in and the to-be-expected impact of
Vendor lock-in is seen as one of the potential drawbacks of cloud computing.
One of Gartner’s research analysts recently published a scenario where
lock-in and standards even surpass security as the biggest objection to cloud
computing. Despite efforts like Open Systems... (more)
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)
You may have missed it in the flurry of news from Apple, but VMware recently
had their annual get-together at the Moscone Center in San Francisco. On
stage VMware shared two key insights: successful virtualization is becoming
more about orchestration and automation than about hypervisors. And,
private clouds will rapidly develop into hybrid clouds. I agree on both but
believe the combination of these two trends has some distinct consequences
that did not get picked up by the media.
Let me start with a disclaimer and some disclosure. I followed the event not
on-site but through ... (more)
Just back from Gitex (more about this later) and it is only one week to go to
Cloud Expo Silicon Valley, which starts Monday November 1st. I will be
speaking in track 4 “Real-World Cloud Computing & Virtualization” on
Wednesday at 6:25 PM (the cloud is no 9-5 affair) about How Cloud and
Virtualization Are Changing the Way Business and IT Will Interact.
After speaking about this in Prague in June I was invited to give my
perspectives also at the event in Santa Clara. Only 5 months have passed, but
in cloud terms that is a life time. Come by and check out what has changed.

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
