Modernization doesn’t have to be a rewrite. This talk shows proven patterns for improving reliability, performance, and maintainability while keeping feature delivery moving and avoiding downtime.
What we cover
- Strangler pattern and incremental routing
- Release strategies: canary, blue/green, and safe rollback
- Data migrations without outages (backfill + cutover)
- Quality gates that prevent regressions during refactors
Practical checklist
- Stabilize interfaces (APIs, contracts, schemas) before refactors.
- Add monitoring and error tracking to reduce uncertainty.
- Ship changes in slices behind flags when behavior changes.
- Automate tests around the most fragile paths first.
Recommended audience
- Engineering leaders managing legacy risk
- Backend and platform engineers
- Teams planning a rewrite or a major migration
