Event Driven Architecture Services
Introduction - event-driven architecture
This designs systems around events and message queues rather than direct service-to-service calls - when an order is placed, an event fires and whichever services need to react (inventory, email, analytics) subscribe independently, rather than the order service calling each one directly and breaking if any single one is slow or down.
For a specific message broker implementation (Kafka), see our dedicated Kafka integration service - this page covers the broader architectural pattern and design decisions, including when other message brokers (RabbitMQ, AWS SQS) fit better than Kafka.
Why event-driven design earns its complexity at certain scale
It solves real problems - services can fail or scale independently without cascading failures, and adding a new consumer of an event doesn't require changing the producer. It also adds real complexity: debugging becomes harder since flow isn't a simple call stack, and eventual consistency requires careful design.
We recommend this pattern where you're genuinely hitting the limits of direct service calls - tight coupling causing cascading failures, or scaling bottlenecks - not as a default architecture for every new system regardless of actual need.
What's included
- Event schema design for your actual business domain events
- Message broker selection matched to your scale and requirements
- Producer/consumer implementation with proper error handling
- Dead-letter queue handling for failed message processing
- Monitoring for event flow and processing lag
- Migration planning if moving from a direct-call architecture
Our process
1. Assess the actual need
We confirm event-driven architecture solves a genuine problem for your system rather than adding complexity without corresponding benefit.
2. Design events & choose broker
Event schemas get designed around your real business domain, with a message broker chosen to match your scale and existing stack.
3. Implement & migrate incrementally
We implement new event-driven flows incrementally rather than a risky full-system rewrite, validating each piece before expanding.
Pricing
Migrating a single critical flow to event-driven design costs less than a full-system architectural migration. Range: Rs 90,000 - 520,000 - indicative, final quote after discovery. Request a quote or WhatsApp +92 324 2991303.
