Key Takeaways
- Strangler Fig pattern for incremental migration
- Containerization strategies for legacy state
- Implementing CI/CD in a highly regulated environment
- Measuring success beyond 'just getting there'
Breaking the Monolith
The biggest hurdle in legacy migration isn't the technology - it's the tangled web of dependencies. By identifying 'bounded contexts' and isolating them one by one, we reduced downtime and risk during the 90-day transition.
Cultural Ready-ness
Cloud native isn't just about Kubernetes; it's about shifting from 'release trains' to 'daily deployments'. We focus on empowering the existing team through the transition to ensure long-term stability.
