Service Oriented Architecture (SOA) is a paradigm for organizing and utilizing distributed services as the basic construct to produce the desired results for service consumers. Large and complex computational units can be composed out of the available services. As the complexity and dynamism of the current global network systems grow significantly, the(More)
Development of internet and World Wide Web technologies has enabled access to many types of services over the web. Large and complex computational units can be built / composed out of the available services. This type of concept and architecture is called Service-Oriented Architecture (SOA). Implementation of SOA brings about challenges which include(More)
Service Oriented Architecture (SOA) technology enables composition of large and complex computational units out of the available atomic services. Due to the dynamic nature of SOA the implementation of SOA brings about many challenges, for instance, in terms of service discovery, service interaction, service composition, robustness, quality of service, etc.(More)
Cloud computing is an extension of Service Oriented Architecture (SOA). For cloud elastic nature, it will often need to dynamically reconfiguring and reorganising the services interaction as some unpredictable events, such as crashes or network problems, will typically cause service unavailability. The complexity and dynamism of current global network(More)
Service Oriented Architecture (SOA) technology enables composition of large and complex computational units out of the available atomic services. Implementation of SOA brings about challenges which include service discovery, service interaction, service composition, robustness, quality of service, security, etc. These challenges are mainly due to the(More)
Service oriented computing is a computing paradigm that utilizes existing services as the basic construct to compose new service / application, with service oriented architecture (SOA) as its architectural concept. A service architecture that is capable of changing its structure and functionality autonomously with little human intervention is required to(More)
Traditional network level firewalls, based on port and IP addresses, are inadequate for dealing with the development of applications and protocols that do not follow the conventions of port services established by IANA (Internet Assigned Numbers Authority). Therefore firewalls capable of accurately classifying and filtering connections based on application(More)
