Better yet, a host of other smaller but meaningful benefits flow from the bigger-picture risk-reduction. Make sure the façade doesn't become a single point of failure or a performance bottleneck. 扼制圖模式 Strangler Fig pattern 06/23/2017 M 本文內容 透過將功能的特定片段逐漸取代成新的應用程式和服務，來逐步移轉舊有系統。Incrementally migrate a legacy system by gradually replacing specific pieces of functionality with Choosing the correct first modules makes or breaks a project.

Strangler fig, also called strangler, many species of tropical figs (genus Ficus) named for their pattern of growth upon host trees, which often results in the host’s death. The Strangler Pattern is a legacy code pattern named after Strangler Fig plants, which grow in rainforests where there is intense competition for sunlight. Jan 26, 2019 - Inspired by the strangler figs in Australia, a strangler fig application gradually draws behavior out of its host legacy application Thomas: We took an API first approach to the development of the services, with a central "monolithic" API that mirrored the database of the application. However, running two separate versions of an application means that clients have to know where particular features are located. The strangler fig patternis a code refactoring method proposed by Martin Fowler that takes an incremental approach to refactor code. Go was started more than a decade ago in the Engineering department at Google. The strangler pattern approach is fundamentally simple. The idea is to create a new application around the old application. A microservice migration suited the requirements of the business and allowed a phased approach.

But there's so much more behind being registered. To re-write stable features for no real benefit beyond the removal of Zope adds the risk of bugs and lost functionality, and also takes resources away from revenue generating work.
