Open Grid Services Infrastructure

 Dynamic Service Creation: The OGSA model can dynamically create and manage new service instances and also can necessitate the existence of service creation services. The OGSA model defines a standard interface (Factory) and semantics which a service creation service must provide [1].  Lifetime Management: Any distributed system is supposed to deal with any number of failures. Especially in a system which involves transient, stateful service instances, there should be an option available to reclaim the lost services and also for recovering the state associated with the failed operation [1].  Notification: The collection of distributed services should be able to alert each other asynchronously when any change occurs to their current state.…

In T8.1, services and their corresponding user communicate with each other by passing data in a well-defined, shared format, or by coordinating an activity between two or more services. The services are located in a central service pool and can use a so-called Service Bus (often Enterprise Service Bus or ESB), should be shared in parallel by different application systems and beyond, combined by a service composition to arbitrarily complex complete systems. This, also called orchestration…

Modern power systems are made up of several interacting national systems. These systems interact providing essential support and monitoring in various power grids or sectors. While the advantages of systems interacting are bountiful in information gathering and sharing, it is not without certain drawbacks. Our society is dependent upon the availability of power and is quickly incapacitated by its loss. Simply observe the moderate disruption that is caused during severe weather. Often, these…

In the mockumentary, “Leaked: The Internet Must Go”, a market researcher, John Wooley, was hired by Internet service providers (ISP) to do market research and talk to people to help them sell their new vision; eliminating net neutrality to reach maximum profit potential.

He praised the professionalism, technical and sales expertise, and individual performance of separate business units, but took a course on integration,…

between the Colombian government and the FARC signed to date (Department U. S., 2013). On April 2015, guerrilla forces killed 11 Colombian soldiers in southwest Colombia. The Colombian government forces retaliated with airstrikes that killed 26 guerrilla forces. This attack from the FARC and retaliation from Colombian forces has hindered the peace talks (Dancis, 2015). A lull in the violence resulting from the cease-fire has impacted both the Colombian government and the FARC. The Colombian…

Only about 25% of the country of Darwin is electrified. For those who are not on the electric grid, lighting is primarily done by kerosene lamps and homemade candles. Kerosene fuel can cost as much as 50 cents a night, a substantial amount of money considering most Haitians only make about 2 dollars a day. Besides cost, kerosene also has many negative health risks, specifically harmful fumes and the risk of broken glass and fire. Due to these factors, many Haitians do not have much if any…

business needs. The collaborative emphasis advanced by this Act would have mitigated and facilitated establishment of a more resilient cybersecurity posture. As far as the critical infrastructure is concerned, the proposed Act recognizes the dependency of the government on the private sector for critical infrastructure and services and calls for collaboration with the private sector to determine cybersecurity performance requirements. The proposed bill targets critical infrastructure that…
