Open Grid Services Architecture

 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…

acted as clients. They enabled a user to access resources over the internet, thus by providing more accessibility and authorization to it. This scenario has been described in figure 1.3, shown above. But all this was very difficult to integrate as far as business data availability and workflows are concerned. So, there emerged a need for some technology wherein one can easily change the software which can easily handle all the resources and workflows according to the requirement. And the answer…

Identifying the Driving Forces in New Marketing Principles and Their Probable Future Changes Krystle Alfonseca LIM College  Marketing principles are the fundamental concept and philosophy that serves as the foundation for promoting a business (sale of goods or services), or a behavior for a chain of reasoning in business domains. Marketing encompasses a spectrum of processes such as identifying consumers ' needs and design a means of providing these needs. Today 's marketing…

in selecting the architecture [13]. 2.1.2 Architectural Design This applies to all architectures, most of the time the genre(category) of the software dictates the architectural approach to be considered, some of the genres are artificial intelligence, commercial and non-profit, communications, financial, games, government, legal, medical, military, science and many more. Each genre has its own unique requirements which it follows with emphasis on its key qualities [19]. The deployment…

The role of software architects is to map the software requirements to the architecture design and guarantee that both functional requirements and quality attributes are met (Qin et al., 2007). Since applications have a diverse set of requirements, it is rare that a single architectural style can address all those requirements. Usually, the system architecture is not limited to a single style, but is often a combination of architectural styles. For example, the design of a web-based application…

This is the where the great works of Spanish born artist Antoni Gaudi, usually considered to be the epitome of architecture in Catalan modernism, recognized as the face of Barcelona architecture. Gaudi’s was born in born in 1852, and his upbringing was not easy. He was the youngest of five, and two of them died because of different types of health related illnesses. The hardships of his youth give us understanding of his work and it allows for a greater appreciation of his art showing strong…

The Villa Savoye is one of the most important modern buildings of the 20th century which incorporated the Le Corbusier’s five principal points of architecture, and it could be the perfect realization of Le Corbusier's principles. This building is located outside of Paris and offers a space for occupants to escape from the crowded Paris. The location of the villa helped Le Corbusier to have freedom in design in order to create a masterpiece which would truly stand the test of time. This building,…

theoreticians like Vitruvius and Marc-Antoine Laugier describe the primitive hut as the origin of architecture. When we look at the standardised model for refugee camps, we see tents – mostly offered by humanitarian organizations – arranged in the form of a grid. The camp is organised hierarchically. It consists of different districts, each subdivided into smaller neighbourhoods. Districts are separated from each other by open spaces, neighbourhoods by roads or smaller paths. A perfect grid…

This principle basically focuses that most of the things are at walking distance only from the place where one lives so that dependency on automobiles can be reduced. It promotes pedestrian friendly street design which means that there is enough good space so one can walk easily. This design includes tree lined streets, hidden parking lots, on street parking etc. The side walks should be minimum of 5feet within Row & parallel to street. 2. Connectivity : …
