AWS Single Architecture (Momo)
2 min read
This design reuses the LG H&H architecture: a Next.js frontend, FastAPI backend on ECS Fargate, AI-service integration, Neptune, and OpenSearch. Momo adds Kinesis Data Streams for live-broadcast events, TimeStream for delivery SLA time series, and multilingual support. The graph is sized at approximately 800K edges.

2. Specialized Components
| Component | Role |
|---|---|
| Kinesis Data Streams | Real-time ingestion of live-broadcast viewing and pin events (S9-Mo) |
| TimeStream | Delivery SLA time series (S10-Mo) — per-fulfillment-center latency |
| OpenSearch + Smartcn | Traditional Chinese morphology + KNN |
| Cohere multilingual | Multilingual embeddings |
3. Cost (8-week PoC)
| Item | Estimate |
|---|---|
| Bedrock + Cohere | $1.8K/month |
| Neptune + OpenSearch | $1.5K/month |
| Kinesis + TimeStream | $0.8K/month (high event volume) |
| ECS + External APIs | $0.5K/month |
| Total | ~$4.6K/month |
