1 Innovative Marriage of Security and Performance in SOA Based Dynamic Enterprises Presented by: Dr. Mehmet Yildiz IBM Certified Executive IT Architect [email protected] S O L E A Service-Oriented Locally adapted Enterprise Architecture Proposed Abstract: “All enterprise systems have two key concerns: security and performance. All CIO / CTOs have these two in their daily agenda through the life cycle of their mission critical business systems. These two aspects hardly go along well unless specialised design considerations, innovative techniques and methodical practices are applied. Finding the right balance for security and performance marriage is a significant challenge for dynamic enterprises especially when the Service Oriented Architecture (SOA) is the key enabler of it. This paper aims at identifying key security and performance factors for SOA projects in dynamic enterprises and how they can be efficiently architected for desired business outcomes. In this paper, the experience based claims are substantiated with industry based literature review and a sample case study from the field.” Sponsors: -Helsinki University of Technology -University of Kuopio Abridged version
