Phase 8 · Serverless & Event-Driven Architecture

Topics

Serverless Databases (DynamoDB On-Demand)

Part of the Cloud Computing Roadmap.

Summary

Database options that scale automatically with usage and charge based on actual read/write activity rather than provisioned capacity — pairing naturally with serverless compute for fully consumption-based architectures.

How to Learn This

  • 1Create a DynamoDB table (or equivalent) in on-demand mode and perform basic operations.
  • 2Learn the difference between on-demand and provisioned capacity pricing models.
  • 3Understand why this pairing (serverless compute + serverless database) minimizes idle-resource cost.
