Whats is DynamoDB?

Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed, multi-region, multi-active, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications.

DynamoDB differs from other Amazon services by allowing developers to purchase a service based on throughput, rather than storage. If Auto Scaling is enabled, then the database will scale automatically. Additionally, administrators can request throughput changes and DynamoDB will spread the data and traffic over a number of servers using solid-state drives, allowing predictable performance.

Technical Details

Amazon DynamoDB is a NoSQL database that supports key-value and document data models. Developers can use DynamoDB to build modern, serverless applications that can start small and scale globally to support petabytes of data and tens of millions of read and write requests per second.

• Microsecond latency with DynamoDB Accelerator
  
• Automated global replication with global tables
  
• Read/write capacity modes
  
• On-demand mode
  
• ACID transactions
• Encryption at rest
  
• Point-in-time recovery
  
• On-demand backup and restore
