DynamoDB
DynamoDB is a fully managed NoSQL service offered by AWS. It is easy to set up with minimal configurations and can scale as required with little to no effort from the developer side. It is highly performant and can provide read and write without latency. It offers security for data at rest by encrypting it. It provides high availability and durability by replicating data to multiple availability zones within a Region. Using SSDs helps it to provide fast access to the stored data as well.

- Items: Items are like the rows in RDBMS tables. Each item identifies one unique entity of a DynamoDB...
