Why Real-Time Matters
Business moves fast. Batch analytics that's hours or days old may miss critical opportunities or threats. Real-time analytics enables immediate response to changing conditions.
Use Cases
Fraud Detection
Catch fraudulent transactions as they happen.
Operational Monitoring
React to system issues immediately.
Dynamic Pricing
Adjust prices based on current demand.
Personalization
Respond to behavior in-session.
IoT and Sensors
Process streaming device data.
Architecture Concepts
Streaming vs. Batch
- Batch: Process data in scheduled chunks
- Streaming: Process data as it arrives
- Lambda: Combine both approaches
- Kappa: Stream-first with replay capability
Key Components
Message Broker: Captures and buffers event streams. Examples: Kafka, Kinesis, Pub/Sub
Stream Processor: Analyzes data in motion. Examples: Flink, Spark Streaming, ksqlDB
Real-Time Database: Serves low-latency queries. Examples: Druid, Pinot, ClickHouse
Visualization: Displays real-time dashboards. Examples: Grafana, custom applications
Implementation Considerations
Latency Requirements
- Near-real-time (minutes): Simpler architecture
- True real-time (seconds): More complex
- Sub-second: Specialized solutions
Data Volume
- Events per second
- Peak vs. average
- Growth trajectory
Accuracy Trade-offs
- Exactly-once processing
- At-least-once with deduplication
- Best-effort for non-critical
Getting Started
- Identify use cases: Where does latency matter?
- Assess requirements: Volume, latency, accuracy
- Start simple: Begin with manageable scope
- Prove value: Demonstrate before scaling
- Build expertise: Streaming is different from batch
Real-time analytics is powerful but complex. Match the solution to actual business needs.
Next Steps
For streaming platforms, see Apache Kafka documentation and AWS Kinesis.
