Module 4.3 Review Snapshot

This module covered the diverse landscape of AWS database and data services. Each service is built for a specific type of workload:

  • RDS/Aurora: Managed relational databases (SQL) for traditional applications.
  • DynamoDB: Serverless NoSQL database for high-scale, single-digit millisecond performance.
  • ElastiCache: In-memory caching (Valkey, Redis, Memcached) to speed up reads.
  • Redshift: Data warehouse for high-performance SQL analytics and BI.
  • EMR: Managed platform for big data frameworks like Spark and Hadoop.
  • Neptune: Graph database for highly connected data and relationships.
  • QLDB: The concept of a ledger database for immutable, verifiable history.

Tip

The Golden Rule: Choose the database that matches your access pattern. Use RDS for relations, DynamoDB for scale, ElastiCache for speed, Redshift for analytics, and Neptune for connections.
