A look at how we designed Hitaji 360's architecture to handle growth — from a handful of users to thousands of concurrent connections.
Why Microservices
When we started building Hitaji 360, we knew it needed to scale. A monolithic architecture would have been simpler initially, but it would have become a bottleneck as we added more products and features. Microservices let each component scale independently.
Our Stack
Each service is containerized with Docker, orchestrated on our infrastructure, and communicates via REST APIs and event-driven messaging. We use PostgreSQL for structured data, Redis for caching, and Socket.IO for real-time features.
Lessons Learned
Microservices aren't free. They add operational complexity, require solid CI/CD pipelines, and demand careful API design. But for a platform like Hitaji 360 that serves multiple products and tenants, the trade-offs are worth it.
