Extending a multi-tenant aware ESB solution with evolution management

Abstract

Services have been improved over time to meet the increasing demand of service consumers. A service could be changed at any state in service life cycle. An inefficient service version management with arbitrary decisions could lead to disconnections between service consumers and service providers. A service version control management system is therefore necessary. The goal of this thesis is to specify, design and implement a service evolution management system for a multi-tenant aware ESB solution, so that the ESB could have the capabilities to manage the changes of multiple service versions between service consumers and service providers in a transparent manner. Furthermore, a function should be provided to check the compatibility between service versions, and, moreover, the calculation of service identifiers should be executed automatically, because service descriptions do not contain version-related information.
