ShopEase's monolithic ASP.NET MVC application crashed every sale event due to database bottlenecks — losing ₹50 Lakhs revenue per outage. Their 12-developer team could deploy only once every 3 weeks because every change required full regression. Scaling required provisioning the entire monolith, not just bottleneck components.
VFL Technologies decomposed the monolith into 9 domain-bounded microservices (Catalog, Inventory, Order, Payment, Shipping, Customer, Notification, Analytics, API Gateway). Each service has its own database (polyglot persistence), communicates via Azure Service Bus for async events and gRPC for sync calls, and deploys independently to AKS. We used the strangler-fig pattern to migrate incrementally over 20 weeks with no production disruption.
Event storming workshops, bounded context identification, and strangler-fig roadmap.
AKS cluster, Azure Service Bus, API Gateway, monitoring stack.
Incrementally extracted 9 services using strangler-fig, service-by-service.
Saga patterns, outbox pattern, and compensating transactions.
OpenTelemetry traces, structured logs, and dashboards across all services.
Azure Load Testing, chaos engineering, and final cutover.
"Our biggest sale event used to be our biggest disaster. Now it's our biggest revenue day with zero incidents. VFL's microservices architecture saved our business."
