From Modules-to-Services: A Conceptual SOA Migration Approach Based on QoS
Mehrosh Khalid, Farooque Azam, M. Aqeel Iqbal · 2012
Even though Service-Oriented Architecture (SOA) has turn out to be accepted in the past few years, the vast majority of legacy architectural systems at a standstill are not modularized to work in an SOA environment. The rich quantity of information that businesses have to manipulate has generated a substantial raise in the complication of the legacy systems that accumulate this information. Whereas heading towards a service-oriented architecture working environment can facilitate in managing this raise, as well as along with, it is vital to conserve the venture of several years of fine-tuning and debugging of the legacy possessions as much as achievable. Transforming legacy architectures toward service-oriented architectural frameworks is a tough job being complex due to the unavailability of suitable approaches and tools. In this paper, a step-wise migration approach is projected to transform legacy architecture into an corresponding architecture composed of a set of services and the implementation of that architecture. The proposed framework, in its every step, takes into consideration part of the existing legacy application and back-track it to its origin to visualize the legacy architectural environment, enabling migration into services in the similar working business environment. In the proposed migration framework, much emphasis is put on the testing, since after each migration step the artifacts are tested to ensure QoS of the new service-oriented application being developed and architectural conformance to the original version.
