Inside the API-First Shift: How Platform Engineering Enables Incremental Legacy Breakup
Platform Engineering, Monday, August 11th, 2025
Platform engineering is transforming how enterprises modernize legacy systems, enabling organizations to dismantle monolithic applications gradually rather than through costly and disruptive 'big-bang' rewrites.
By embedding secure APIs, automated delivery pipelines, observability and service discovery into developer workflows, platform teams can manage risk, maintain uptime and accelerate the transition to modern architectures.
Rather than replacing entire systems in one move, platform teams increasingly use the Strangler Fig Pattern-incrementally building new functionality around legacy systems and replacing them piece by piece.
'Platform engineering supports the gradual modernization of legacy systems by creating the infrastructure and tooling that make incremental change safe, fast and repeatable,' said Derek Ashmore, AI enablement principal at Asperitas.
