Web services from a service provider perspective
Klaus Haller · ACM SIGSOFT Software Engineering Notes · 2011
While web service discovery and composition are important for web service "consumers", service providers face other challenges. This paper looks on their needs in an important commercial scenario. In this scenario, bundling service providers combine backend services provided by a backend service provider relying on multi-tenant information systems. Multi-tenant systems allow for economies-of-scale -- a prerequisite for the provider's commercial success. The application management of multi-tenant systems demands for tenant management services such as tenant export or upgrade. This paper describes their implementation. Based on experiences in various banking projects, it provides blueprints for sustainable infrastructures having to run for many years.
