Modernizing Legacy APIs with GraphQL, Microservices, and AI

Blueprint to evolve SOAP/XML monoliths into versionless GraphQL APIs, domain-driven microservices, and scalable NoSQL—using adapters, strangler-fig, and AIOps.

Learn a practical path to modernize legacy SOAP/XML APIs and monoliths into versionless GraphQL APIs, domain-driven microservices, and scalable data stores. We cover adapter-based API rollout, the strangler-fig pattern, dual-write/read migration, and AIOps for resilience—without sacrificing availability or velocity.

Key takeaways:
- Inventory and cluster legacy APIs; translate contracts to GraphQL/OpenAPI with AI-in-the-loop
- Generate adapters to front new APIs with old backends for quick rollout
- Documentation and client migration automation to reduce friction
- Strangler-fig facade/proxy for routing and controlled ramp-up/down
- Identify domain boundaries, build dependency maps, and decompose to microservices
- Data store modernization: RDBMS → NoSQL with dual write/read cutover
- Observability, resilience patterns, and predictive health (AIOps)
- Outcomes: lower latency, higher availability, on-demand releases
