Layers of IoT - Upper Stack
IoT architecture typically consists of several layers, each serving a specific function in the overall system. These layers can be broadly divided into the lower stack and the upper stack.
The upper stack deals with application, data processing, and user interaction aspects of IoT systems. It includes the following layers:
Data Ingestion Layer
- Different Data formats (JSON, Binary)
- Message Brokers and queuing systems (RabbitMQ, Apache Kafka)
Data Processing & Storage
- Time Series Databases like InfluxDB / TimescaleDB.
- Hot vs Cold storage strategies.
- Data aggregation techniques.
- Edge vs Cloud processing decisions.
Analytical Layer
- Realtime analytics
- Vizualization frameworks and tools
- Anomaly detection systems
Application Interface / Enablement
- API (RESTful services)
- User authentication / authorization
Enterprise Integration
- Data transformation and mapping
- Integration with legacy systems
