Cloud Computing Will Usher in a New Era of Science Discovery

January 26, 2010

Computation is commonly considered the third mode of science, where the previous modes or paradigms were experimentation/observation and theory. With the introduction of high performance supercomputers, the methods of scientific research could include mathematical models and simulation of phenomenon that are too expensive or beyond our experiment's reach. With the advent of cloud computing, a fourth mode of science is on the horizon. Read more…

Security — The Dark Side of the Cloud

January 25, 2010

Despite the many benefits to cloud computing, security remains one of the biggest challenges. IT organizations have a hard enough time defending their in-house private cloud resources. Companies offering public cloud, pay-for-usage models are faced with a more difficult challenge since they must serve multiple organizations on the same platform. In response to security threats, there is an opportunity for innovation of flexible cloud-based security service offerings. Read more…

The Impact of Cloud Computing on Corporate IT Governance

January 25, 2010

While cloud computing is enabling some fundamental changes on how IT groups deliver services, from a corporate management viewpoint, the basic principles of IT governance still remain true. However, the advent of cloud computing is having an increasing impact on how the components of the governance process are executed. For the purpose of this article, we will use the COBIT model (Control OBjectives for Information and related Technology) that is comprised of five major process focus areas: Strategy Alignment, Value Delivery, Resource Management, Risk Management, and Performance Measurement.

The Impact of Cloud Computing on Internal IT Governance

January 25, 2010

In theory, the realization of IT governance should be a seamless process running from the board room to actual delivery of IT services. In practice however, many organizations have an institutionalized steering committee with its associated processes that supports the organization's IT related goals while the IT group has a leadership team or council whose governance activities are focused inward on such things as technical issues, standards, and resource management.
