摘要：Evolution has always been a challenge for enterprise computing systems. The microservice
based architecture is a new design model which is rapidly becoming one of the most effective
means to re-architect legacy enterprise systems and to reengineer them into new modern
systems at a relatively low cost. This architectural style has evolved based on a number of
different approaches and standards. However, there are quite a few technical challenges which
emerge when adopting microservices to revive a legacy enterprise system. In this paper, an
evolution framework and a set of feature-driven microservices-oriented evolution rules have
been proposed and applied to modernise legacy enterprise systems, with a special emphasis on
analysing the implications as regards runtime performance, scalability, maintainability and
testability. Testing and evaluation have been carried out in depth, aiming to provide a guidance
for the evolution of legacy enterprise systems.
