Scalability & Throughput Evolution

4-Tier Architectural Progression

Scales horizontally with stateless Docker containers orchestrated via Kubernetes or AWS ECS with PgBouncer connection pooling.

Tier
Phase 1

Small Scale

MVP & Early Deployments

Single NestJS container running on Node.js connected to a managed PostgreSQL instance.

Tier
Phase 2

Medium Scale

Growth & Clustering

Multiple NestJS container instances behind an ALB with Redis caching and TypeORM connection pooling.

Tier
Phase 3

Large Scale

High Concurrency & Caching

Microservice architecture communicating over RabbitMQ/Kafka or gRPC transports with PostgreSQL read replicas.

Tier
Phase 4

Enterprise Scale

Global & Distributed

Distributed Kubernetes cluster with service mesh (Istio), distributed tracing, and multi-region database clustering.
