DynamoDB can handle more than 10 trillion requests per day and can support peaks of more than 20 million requests per second.
DynamoDB is serverless with no servers to provision, patch, or manage and no software to install, maintain, or operate.
DynamoDB automatically scales tables up and down to adjust for capacity and maintain performance.
Availability and fault tolerance are built in, eliminating the need to architect your applications for these capabilities.
Using DAX (in-memory cache), you can improve the read performance of your DynamoDB tables by up to 10 times.
DynamoDB supports both key-value and document data models. This enables DynamoDB to have a flexible schema, so each row can have any number of columns at any point in time. This allows you to easily adapt the tables as your business requirements change, without having to redefine the table schema as you would in relational databases.
By default, DynamoDB encrypts all data and provides fine-grained identity and access control on all your tables.
DynamoDB supports ACID transactions to enable you to build business-critical applications at scale.
DynamoDB global tables replicate your data automatically across your choice of AWS Regions.
You can create full backups of hundreds of terabytes of data instantly with no performance impact to your tables, and recover to any point in time in the preceding 35 days with no downtime.
DynamoDB is also backed by a service level agreement for guaranteed availability.
