Out With the Old, In With the New (Strategically)
Many established US enterprises are burdened by legacy systems that are costly to maintain and hinder agility. **Legacy system modernization** is a key part of Digital Transformation, but it needs a careful approach.
Modernization Options
- Rehosting (Lift and Shift): Move the application to the cloud with minimal changes. Quick win, but doesn’t solve underlying issues.
- Replatforming: Make some cloud optimizations during the move. Better performance, some cost savings.
- Refactoring/Rearchitecting: Significantly modify or restructure the application to be more cloud-native (e.g., microservices). Most complex, but greatest long-term benefits.
- Replacing: Retire the old system and move to a SaaS solution or build new.
The right strategy depends on the system’s business value and technical condition.
