Introduction to Evolving Data Architectures
The data landscape has undergone significant transformations across three major eras:
- Big Data 1.0: BI and Data Warehouse era
- Big Data 2.0: Web/APP transition period
- Big Data 3.0: Current IoT-driven paradigm
Each phase brought architectural shifts to accommodate changing data processing needs. Let's examine how these architectures compare in today's IoT-driven world.
Lambda Architecture: The Traditional Approach
👉 Discover how modern architectures handle massive data loads
Core Components
- Batch Processing Layer: Handles historical data (MapReduce, Hive, Spark SQL)
- Speed Layer: Manages real-time processing (Storm, Flink, Spark Streaming)
- Serving Layer: Merges results for consumption
Advantages
✔️ Stable and time-tested
✔️ Separates computation peaks between day/night cycles
✔️ Cost-effective for predictable workloads
Critical Limitations
- Inconsistent results between batch and real-time processing
