NoSQL databases provide flexible schemas for building modern applications. They are widely recognized for their ease of development, functionality, and performance at scale. Amazon DynamoDB provides fast and predictable performance with seamless scalability for NoSQL databases in the Amazon Web Services (AWS) Cloud. As a fully managed database service, DynamoDB helps you offload the administrative burdens of operating and scaling a distributed database. You don't have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling.
