### Features

In  last page, Relational DBs were discussed. The service offering from Amazon for Non-Relational DBs which supports NoSQL for querying part, is Amazon DynamoDB.

Unlike Amazon RDS, which is a PaaS, since this is a SaaS offering, not only, it is fully managed, it is also not required to manage the database layer, so need to think of schema

It provides both key-value and document database.

It provides consistent, single-digit millisecond response times at any scale.

It supports ACID (Atomicity, Consistency, Isolation and Durability) transaction

It supports Identity and Access controls on Table

It supports automated scaling without excessive maintenance and has extremely low latency

It offers in-memory cache with DynamoDB Accelerator (DAX)

It supports server-less applications and it autoscales to support growing demand
