💡 Model Answer
DynamoDB is a fully managed, serverless NoSQL database that offers predictable single‑digit millisecond latency and elastic scaling. It is ideal for use cases that require:
- High write/read throughput – e.g., real‑time analytics, gaming leaderboards, or IoT telemetry.
- Serverless architectures – it integrates with Lambda, API Gateway, and EventBridge, eliminating the need to provision servers.
- Global distribution – Global Tables provide multi‑region replication with low latency for worldwide users.
- Fine‑grained access control – IAM policies can target specific tables or items.
- Event‑driven processing – Streams can trigger Lambda functions for real‑time data pipelines.
Typical examples include session stores, shopping cart services, user profiles for mobile apps, and any scenario where a simple key‑value or document model suffices and you want to avoid operational overhead.
