Abstract
To facilitate efforts to transform the domain-specific business vendor to be customer-centered, results-oriented, and market-based cyber-organization or e-organization, with the advances of Advanced Computing Technologies (ACT). In this paper we propose an engineering methodology and theoretical framework of constructing of an open, shared, collaborative multiple-tenant, multiple-organization domain-specific (SMEs enterprise, education, healthcare & wellness, farming etc.) digital service ecosystem. The theoretical description of Cloud-based Open Cyber Infrastructure (COCI) model, as well as the software infrastructure for such a model, are developed to implement the knowledge-intensive cyber-service environment for the domain-specific business vendors. Our approach provides an ACT solution to transform the physical-vendors into cyber-vendors or e-vendors with the low-cost, high-availability, economical. At the same time, we put the forward the concept of Knowledge-intensive Model as a Service (KMaaS) to meet the need of enhance the productivity and service pattern reshaping
