What is the Strangler Fig pattern and its use in legacy modernization?
Tests incremental modernization over big-bang rewrites. A strong answer covers the botanical metaphor, building new components alongside legacy, routing traffic, extracting seams, and four activities. Red flag: a long rewrite delivering no value until launch.
Tests whether you understand incremental legacy modernization over big-bang rewrites in agile contexts. A strong answer describes the botanical metaphor; explains building new components alongside legacy, incrementally routing traffic to them, and extracting seams; references Cartwright, Horn, and Lewis four activities around outcomes, parts, delivery, and organization; and notes transitional architecture. Red flag: proposing a monolithic years-long rewrite that delivers zero user value until a risky big-bang cutover.
