Lately in the IT community all the hype is on Cloud Computing. We have small
start-ups offering several variations of Cloud services as well as some of
the established big players (Google, Amazon, IBM, Novell (aimed at cloud
service providers),Sun) stepping up their offerings of cloud services.
But what exactly is Cloud Computing? Is it Virtualization? Is it services
that we accessed via a web browser over the years, something totally new, or
is it all of these,but just rebranded?
The term Cloud Computing started gaining traction when Google and IBM
launched a university initiative to address internet scale computing back in
These services has been evolving since the 90s and its previous incarnations
can be said to be Grid and Utility computing and the Software as a Service
offerings we saw around a decade ago.

In an earlier article, I stated that we can view Service-Oriented
Architecture (SOA) as a synthesis of Enterprise Application Integration (EAI)
platforms with middleware tools. This evolution has evolved into an
architectural style which, entities can then utilize to execute and align key
services with their operational model to achieve strategies, goals and

Last week at the 7th International Cloud Expo in Santa Clara, I sat on a
panel discussing virtualization and the cloud. As a follow on to my
contribution, it is my intention to expand on the position of virtualization
and the cloud ecosystem.
It is generally accepted that the concept of cloud computing or, at least the
amalgamation of services that infer the cloud ecosystem, lends to the premise
of improvements in managing deployed services. This due to an assumed
increase in efficiencies resulting from the sharing of hardware resources at
one end of the spectrum.
According to ... (more)
Expanding on the " introduction to cloud computing" article, here are some
additional suggestions for choosing a cloud service model provider.
In a typical Cloud Computing data centre, an application set will generally
be hosted over Virtual Machines running on a large number of Physical
Total Cost of Ownership (TCO) is a definite factor when considering a move
for some enterprise services into the cloud. There are certainly arguments
both for and against the merits, especially when considering the impact of
risk on an enterprise that choses to transfer risk with the a... (more)
I've been asked quite a few times, "when will it be a good time to get into
cloud computing?" by potential clients. My answer is typically it depends...
I know, I know.... not much direction there, but really it all depends. Why ?
Well, some may state, "we all know of the much beaten security concerns, and
we will ensure that systems on our end are secured and synced to work in
tandem with the vendors' security."
Can one ensure some degree of monitoring by the implementation of an
Intrusion Detection System (IDS) residing within the system hosting the
gateway into the cloud?
