Amazon DynamoDB is a quick and flexible NoSQL (Non-Relational Database) service for applications that require consistent, millisecond latency.

It is scalable and fully managed by AWS, so you no longer have to worry about the administration side of maintaining and expanding database capacities.

It can hold exceptionally large amount of data that can be searched very quickly, and supports both document and key-value store models, and offers built-in security, backup/restore, and in-memory caching.  It run s on an SSD-backed indexed datastore, and instead of “provisioning” storage, you simply pay for what you use.

There are no charges for data transferred between DynamoDB and other services within the same region.  Data transferred cross-regions are charged on both sides of the transfer.

It also offers Encryption at Rest, so your sensitive data is secure, and you no longer have to worry about the operational and logistical complexity of protecting the data yourself.  It also provides on-demand backup capability for your archival and retention regulation compliance needs.

Global Tables

Global Tables fully automates replication of tables across Regions.  This enables you to have a fully managed, multi-region and multi-master database with quick local read and write performance.
