  • DynamoDB can handle more than 10 trillion requests per day.
  • DynamoDB is serverless as there are no servers to provision, patch, or manage.
  • DynamoDB supports key-value and document data models.
  • DynamoDB synchronously replicates data across three AZs in an AWS Region.
  • DynamoDB supports GET/PUT operations using a primary key.
