That old system running your business might work, but it's probably costing you more than you think.
Signs You Need Modernisation
- High maintenance costs
- Integration difficulties
- Skills shortage for the technology
- Security vulnerabilities
- Poor performance
- User frustration
Modernisation Approaches
1. Encapsulation
Wrap the legacy system with APIs so new applications can interact with it.
2. Replatforming
Move to modern infrastructure with minimal code changes.
3. Refactoring
Restructure and optimise code while preserving functionality.
4. Rebuilding
Rewrite from scratch using modern technologies.
5. Replacing
Replace with off-the-shelf software.
The Strangler Fig Pattern
Gradually replace legacy components with new ones, routing traffic to new services until the old system can be retired.
