To fulfill the above requirements, we introduced the following solution:

• We recommended DynamoDB as the optimal solution for this scenario. DynamoDB is a cloud-based NoSQL database known for its exceptional scalability and robust replication capabilities.
• We implemented AWS DynamoDB with the appropriate number of Read capacity units.
  and Write Capacity units.
• DynamoDB is native to AWS, and we are also utilizing Elasticsearch, which is also offered by AWS.
• When an update occurs in DynamoDB, a Lambda trigger (defined in AWS) is executed.
  This trigger runs a small python script that replicates all updates from DynamoDB into
  ES.

Deployment

• Migration from a relational database to Amazon DynamoDB.
• Migration from MongoDB, Cassandra, or other NoSQL solution to Amazon DynamoDB. The new application that primarily uses Amazon DynamoDB for its database storage.
• A description of the primary key design for each table and index and why it meets best practices as described in the Amazon DynamoDB developer guide.
• Continuous Back-Ups
• Data Encryption
