This paper extends the current Service-Oriented Architecture (SOA) to introduce a Consumer-Centric Service-Oriented Architecture (CCSOA) paradigm. The current SOA is producer-centric, because the basic idea is that service providers publish services that they produce and let the consumers to search available services to compose their applications. CCSOA focuses on consumers' publishing the services they need and even the applications they need. The service providers must produce services that are in need. This new paradigm extends the design and code sharing, and thus further improves the software productivity. This paper presents the concepts, architecture, enabling techniques, and illustrative examples.
