A company has a web application that includes an embedded NoSQL database.

This solution will meet the requirements of high availability and eventual consistency with the least operational overhead. By modifying the Auto Scaling group to use EC2 instances acrossthree Availability Zones, the web application can handle the increase in traffic and tolerate the failure of one or two Availability Zones. By migrating the embedded NoSQL database to Amazon DynamoDB, the company can benefit from a fully managed, scalable, and reliable NoSQL database service that supports eventual consistency. AWS Database Migration Service (AWS DMS) is a cloud service that makes it easy to migrate relational databases, data warehouses, NoSQL databases, and other types of data stores. AWS DMS can migrate the embedded NoSQL database to Amazon DynamoDB with minimal downtime and zero data loss.
