  • Flexible deployment: Run on YARN, Mesos, Kubernetes, or standalone clusters
  • Growing ecosystem: Integration with edge computing, agentic AI, and multimodal workloads

Pricing Model

Spark is free and open-source, but infrastructure costs apply:

  • Software: Free (Apache License)
  • Infrastructure: $300-10,000+/month depending on cluster size

Apache Hadoop: The Cost-Effective Foundation

What Is Apache Hadoop?

Apache Hadoop is an open-source framework for distributed storage (HDFS) and processing (MapReduce) of massive datasets. While MapReduce has been largely superseded by Spark for processing, HDFS remains a cornerstone for cost-effective big data storage.

Key Features (2026)

  • HDFS (Hadoop Distributed File System): Fault-tolerant storage with data replication across nodes
  • YARN (Yet Another Resource Negotiator): Resource management for running various processing engines
  • MapReduce: Batch processing framework (slower than Spark but highly reliable)
  • Ecosystem tools: Hive (data warehousing), HBase (NoSQL database), Pig, Tez, Ozone
  • Commodity hardware: Designed to run on inexpensive servers
  • Strong security: Storage encryption, access control, and authentication

Pricing Model

Hadoop is free and open-source with lower infrastructure costs:

  • Software: Free (Apache License)
  • Infrastructure: $200+/month (lower than Spark due to disk-based processing)
  • Commodity hardware: Can run on cheaper servers than Spark
  • Managed services: Hadoop-as-a-Service options available for reduced operational overhead

Best Use Cases

  • Data lakes: Storing massive amounts of raw data for future processing
  • Batch processing: Overnight reports, log processing, data transformations
  • Data archiving: Long-term storage of historical data
  • Cost-sensitive operations: When budget is the primary constraint
  • Data warehousing: Using Hive for SQL-like queries on large datasets

Strengths

  • ✅ Lowest infrastructure costs (commodity hardware, disk-based)
  • ✅ Excellent fault tolerance and reliability
  • ✅ Mature ecosystem with proven tools (Hive, HBase, etc.)
  • ✅ Strong security features
  • ✅ Ideal for massive-scale data storage

Limitations

  • ❌ Slower processing than Spark (disk-based I/O)
  • ❌ Not suitable for real-time analytics
  • ❌ MapReduce code is verbose and complex
  • ❌ Declining popularity for active processing (though HDFS remains relevant)
