Updex Solutions, Inc. develops applications and middleware systems for the travel industry. Due to the unique characteristics of supply chains in this industry and increasing demand for higher performance in related software systems, the company has been working on utilising the most advanced software technologies to create resilient, scalable, and responsive systems. To make the solutions more affordable for its target customers (small and medium travel businesses), the company is working on an SaaS (Software as a Service) platform, for which, after extensive exploration, an actor-based architecture has been selected as the best fit. An appropriate fundamental architecture will be of long-term benefit to the company in the development of software that is able to provide such services. Difficulty of finding personnel with specific expertise in actor-based systems is a significant barrier to achieving these goals. Updex would like to work with Prof. Jamali's team to develop Actors based engineering methodologies for SaaS, as well as to design and prototype a software system targeted at the company's SaaS requirements. The project will develop software engineering methodologies based on the Actors model to improve programmability of provision of diverse types and qualities of services to different clients served by a common Actors-based server. This will be accomplished in two ways. First, high-level programming constructs will be designed to improve programmability of differentiated service types for different clients. Second the project will build specific mechanisms based on Dr. Jamali's CyberOrgs model, which will help customize and isolate parts of Updex's SaaS backend for supporting a rich set of multi-tenancy capabilities including provision of differential quantities and qualities of service to clients.
