Q10

Scenario: We are migrating a monolithic e-commerce application to microservices on Kubernetes. How do you plan this migration?

💬Answer
  1. Decompose the Monolith: Split the monolith into logical services (e.g., cart, payment, inventory) using the Strangler Fig Pattern, wrapping monolithic endpoints in APIs.
  2. Database-Per-Service Migration: Split the central database. Deploy CDC (Change Data Capture) pipelines to sync and transition database states gradually.
  3. Deploy API Gateway: Route incoming client requests through an API Gateway (like Emissary-ingress or Kong) to route traffic dynamically to the monolith or newly migrated microservices.
