[Adopted from my BLOG December 2009] 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 2007. 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.

Choosing Your Cloud Vendor

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 Machines. 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)

Service-Oriented Architecture & Cyber Security

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 objectives. Most who interact with or have interacted with the Department of Defence (DoD), will know of the various domains through which operations are implemented. As with any effective entity within the federal realm, t... (more)

Live Forensics and the Cloud

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)

Standards Acceleration to Jump-Start Adoption of Cloud Computing

One major concern with the adoption of cloud computing is the lack of a defined standard or standards that are specific to operations impacting security, interoperability & mobility within the Cloud ecosystem. As most managers of security departments will attest to, there is a fine line between security and operations. While we as business managers want to ensure that we maximize the ROI on our operational investments and ensure that availability is paramount  for our users, we do not want to do so at the expense of our security measures, policies and protocols. On the other hand... (more)
