What is the Strangler Fig pattern?
To understand what the Strangler Fig pattern is, it is probably best to describe where it derived its name from.
In nature, a fig tree often begins to grow on another tree (the host tree) and finally wraps its roots around it, slowly strangling and engulfing the host tree’s growth. This phenomenon is known as the Strangler Fig pattern. The host tree is eventually killed and replaced by a new fig tree as a result of the strangler fig’s roots absorbing nutrients and water from it. This pattern is an illustration of the natural process of resource rivalry, in which one species subjugates another by using its resources.
In software development, the Strangler Fig pattern is used as a metaphor to describe how a new software system replaces an older one by gradually absorbing its resources and functions without substantially altering the previous system.
