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 adoption of a
However as a customer you should ensure resources are in place to safeguard
the maintenance and management of your identity management and authentication
systems. Keep in mind that in the dynamic cloud computing environment
traditional security practices may not ... (more)

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 a... (more)
Cloud Computing offers a sense of "vastness" in terms of storage and remote
processing. According to Simpson Garfinkil, a major challenge to any digital
forensics investigator investigating data within the cloud; can be an
inability to locate or identify data or code that is lost when single data
structures are split into elements.
This in effect directly impacts forensic visibility.
Within this ecosystem a major concern can be access to and the preservation
of data within an on-going digital forensic investigation. Of consideration
as mentioned in Part 1 - is that in a live and ... (more)
With the advent of Web 2.0 and onward, the rise of the terminology and
concept we call Cloud Computing, coupled with an increase in the manner
technologies are being used, not only by corporations but by individuals as
well, comes an increased drive to ensure that risk is managed, effective
security measures to protect identities are implemented, and efforts are
expended to ensure privacy is maintained.
A few years ago, in their quest to implement and maximize on the benefits of
Service-Oriented Architecture (SOA), researchers at Microsoft separated SOA
into four areas (1) viz.
Proponents of the cloud ecosystem touts its "vastness, flexibility and
scalability as advantages for the implementation of cloud services. However,
from a digital point of view this can be a veritable forensic challenge as we
view the cloud in terms of its scope and diversity.
According to Dr. Stephen Wolthusen "Digital forensics (also referred to at
times as computer forensics) encompasses approaches and techniques for
gathering and analyzing traces of human and computer-generated activity in
such a way that it is suitable in a court of law."
A key challenge to a digital inve... (more)
