“…Educational and academic organisations are using the same types of data because interoperability and data integration exist in the NREN e-learning architecture. At the same time, other cloud-computing solutions have challenges in security, high performance and interoperability (De Carvalho et al, 2017).…”

National Research and Education Networks (NRENs) are for sharing resources among member organisations. NRENs play an important role in e-learning activities as they enable cross-organisational communication. Heterogeneous infrastructures used for e-learning are a challenge for system design, data integrity, and interoperability. This paper proposes an NREN e-learning reference architecture and affiliated NREN e-learning design patterns that consider communication, reliable access, a collaboration and interoperability between e-learning infrastructures. Research exists about different architectures including traditional e-learning systems, service-oriented cloud computing such as the service-oriented architecture (SOA) adaptations for education systems, e-learning systems and a service-oriented cloud computing architecture (SOCCA). However, no research has been carried out for NREN e-learning architectures. For deeper insight, we investigate in this paper an e-learning architecture based on the Afghanistan Research and Education Network (AfgREN). The reference e-learning architecture based on AfgREN provides guidance for the rapid development of different e-learning services and learning-analytical infrastructure for Afghanistan.

Cloud computing is one of the most important computing patterns that use a pay-as-you-go manner to process data and execute applications. Therefore, numerous enterprises are migrating their applications to cloud environments. Not only do intensive applications deal with enormous quantities of data, but they also demonstrate compute-intensive properties very frequently. The dynamicity, coupled with the ambiguity between marketed resources and resource requirement queries from users, remains important issues that hamper efficient discovery in a cloud environment. Cloud service discovery becomes a complex problem because of the increase in network size and complexity. Complexity and network size keep increasing dynamically, making it a complex NP-hard problem that requires effective service discovery approaches. One of the most famous cloud service discovery methods is the Ant Colony Optimization (ACO) algorithm; however, it suffers from a load balancing problem among the discovered nodes. If the workload balance is inefficient, it limits the use of resources. This paper solved this problem by applying an Inverted Ant Colony Optimization (IACO) algorithm for load-aware service discovery in cloud computing. The IACO considers the pheromones’ repulsion instead of attraction. We design a model for service discovery in the cloud environment to overcome the traditional shortcomings. Numerical results demonstrate that the proposed mechanism can obtain an efficient service discovery method. The algorithm is simulated using a CloudSim simulator, and the result shows better performance. Reducing energy consumption, mitigate response time, and better Service Level Agreement (SLA) violation in the cloud environments are the advantages of the proposed method.

“…A service level agreement [65,66] is a formal agreement, which helps to identify cloud consumers' expectations, clarify responsibilities, and facilitate communication between providers and consumers. Cloud consumers need proper agreements before the migration of their infrastructure to cloud data center and, the providers need SLA to ensure the delivery of quality services to end-users [67]. It is difficult to satisfy the consumer's need from the perspective of service providers and thereof an optimal strategy is to be arrived through the process called 'Negotiation' [68].…”

Services computing plays a vital role in the field of information technology and enables users to perform web and cloud services in more efficient and effective manner. In the life cycle of services computing, phases such as service discovery, composition, and delivery of services and managing services as per the Service Level Agreements (SLA) have been received significant attention by the research community. Though web services and cloud services are two instances of services computing, their user communities significantly differ in various aspects, which include service specification, consumption, and adherence to service agreements. This paper approaches services computing from the perspective of two architectural paradigms namely Service-oriented Architecture (SOA) and Cloud computing. The existing research attempts performed in the phases of service discovery, composition and provisioning of services as per the SLA has been extensively reviewed from the perspective of SOA and Cloud. Based on the literature review, a number of research issues are also summarized towards achieving service excellence further. At the end, the paper emphasizes the need for service-oriented broker to enhance the discovery and provisioning process of cloud services.
