Amazon DynamoDB is a fully managed, serverless, key-value and document NoSQL database service designed for flexibility, scalability, and high performance. Developed by Amazon Web Services (AWS), DynamoDB enables users to create and manage databases without needing to provision or administer servers. It is optimized for applications requiring low-latency data access at any scale, making it ideal for real-time applications, gaming, ad-tech, and IoT use cases.

DynamoDB provides a flexible data model that supports both key-value and document data structures. Users can define primary keys (partition keys and optional sort keys) to organize data efficiently, while secondary indexes (global and local) allow for flexible querying. The service automatically scales storage and throughput capacity based on demand, ensuring consistent performance even under heavy loads.

Security and compliance are central to DynamoDB’s design. It integrates with AWS Identity and Access Management (IAM) for fine-grained access control, supports encryption at rest, and complies with industry standards like SOC, ISO, and HIPAA. Data replication occurs across multiple Availability Zones within a region to enhance durability and availability.

DynamoDB also offers features like time-to-live (TTL) for automatic data expiration, on-demand and provisioned capacity modes for cost management, and stream integration for real-time event processing. The service supports backup and point-in-time recovery for disaster recovery and data restoration needs.

Pricing is based on read/write capacity units, storage, and data transfer, with options for pay-as-you-go or reserved capacity for predictable workloads. DynamoDB is widely adopted for its simplicity, scalability, and seamless integration with other AWS services, making it a popular choice for modern cloud-native applications.
