Multifaceted Web Services: An Approach to Secure and Scalable Grid Scheduling

Abstract

A multifaceted or multi-interface web service is a web service that offers interfaces to clients and to other peer web services. The multifaceted web service uses a generic parameter-based approach developed in this paper to allow for collaboration between web servers. This parametric approach solves security and scalability problems and is found to be applicable in many situations. Such an approach is necessary to permit easy collaboration and secure resource sharing. We describe one instantiation of such an approach in the form of a global grid scheduler for data parallel (or Single Program Multiple Data) programs. This scheduler demonstrates the usefulness of our approach in current business environments where administrative policies are a major factor in scheduling decisions.

Security‐aware scheduling model for computational grid

“…This privately owned, heterogeneous, nondedicated network of computers utilizes the idle time of thousands of computing devices across the globe to produce the computing power of expensive supercomputers. The key factors in making grid computing feasible are: the evolution of standards such as TCP/IP and Ethernet in networking; the ever‐increasing bandwidth on networks reaching into the gigabit range; the increasing availability of idle CPU cycles on networked PCs, workstations and servers; and the emergence of Web services as a logical and open choice for software computing tasks .…”

A Security Prioritized Computational Grid Scheduling Model

“…There are four factors behind the growing interest in grid computing: the evolution of key standards such as TCP/IP and Ethernet in networking; the ever-increasing bandwidth on networks reaching into the gigabit range; the increasing availability of idle megaflops on networked PCs, workstations and servers; and the emergence of Web services as a logical and open choice of software computing tasks (Prabhakar, Ribbens and Bora, 2002;Naedela, 2003). Grid scheduling software considers a job composed of tasks; finds suitable processors and other critical resources on the network; distributes the tasks; monitors their progress and reschedules any tasks that fail.…”
