Strangler Fig Pattern vs Big Bang Rewrite
Developers should use this pattern when they need to modernize a large, monolithic legacy application that is difficult to maintain or scale, but cannot be replaced all at once due to business continuity requirements meets developers might consider a big bang rewrite when a legacy system is so outdated, poorly documented, or tightly coupled that incremental changes are impractical or too costly. Here's our take.
Strangler Fig Pattern

Strangler Fig Pattern
Nice PickDevelopers should use this pattern when they need to modernize a large, monolithic legacy application that is difficult to maintain or scale, but cannot be replaced all at once due to business continuity requirements
Pros
- +It is particularly useful in scenarios where the legacy system is critical to operations, allowing teams to incrementally refactor or rebuild components while keeping the overall system functional
- +Related to: microservices, refactoring
Cons
- -Specific tradeoffs depend on your use case
Big Bang Rewrite
Developers might consider a Big Bang Rewrite when a legacy system is so outdated, poorly documented, or tightly coupled that incremental changes are impractical or too costly
Pros
- +It's suitable for small to medium-sized systems where the team can afford a complete halt and rebuild, often to adopt modern technologies, fix architectural flaws, or meet new business requirements quickly
- +Related to: legacy-system-migration, refactoring
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Strangler Fig Pattern if: You want it is particularly useful in scenarios where the legacy system is critical to operations, allowing teams to incrementally refactor or rebuild components while keeping the overall system functional and can live with specific tradeoffs depend on your use case.
Use Big Bang Rewrite if: You prioritize it's suitable for small to medium-sized systems where the team can afford a complete halt and rebuild, often to adopt modern technologies, fix architectural flaws, or meet new business requirements quickly over what Strangler Fig Pattern offers.
