Database

Amazon DynamoDB

A serverless, fully managed NoSQL key-value and document database designed for consistent performance at scale.

Key points

  • DynamoDB does not require customers to manage database servers.
  • Its data model and access patterns differ from relational joins and SQL schemas.
  • Capacity options and automatic scaling support variable workloads at a high level.

Best-known use cases

  • Store key-value or document data with low-latency access.
  • Use a managed NoSQL database for large-scale applications.

What candidates often confuse it with

  • DynamoDB is NoSQL; RDS/Aurora are relational.
  • ElastiCache accelerates access with in-memory caching rather than replacing every durable database.

Key Cloud Practitioner takeaway

NoSQL key-value or document data with serverless management points to DynamoDB.
