Colombo is a lightweight platform for developing, deploying, and executing service-oriented applications. It provides optimized, native runtime support for the service-oriented computing model, as opposed to the approach of layering service-oriented applications on a legacy runtime. This approach allows Colombo to provide high runtime performance, a small footprint, and simplified application development and deployment models. The Colombo runtime natively supports the full Web Services (WS) stack, providing transactional, reliable, and secure interactions among services. This paper describes these and other aspects of the architecture, design principles, and capabilities of the Colombo platform.
