Export

A company has a web application that includes an embedded NoSQL database. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Amazon EC2 Auto Scaling group in a single Availability Zone.

A recent increase in traffic requires the application to be highly available and for the database to be eventually consistent

Which solution will meet these requirements with the LEAST operational overhead?

A.
Replace the ALB with a Network Load Balancer Maintain the embedded NoSQL database with its replication service on the EC2 instances.
Answers
A.
Replace the ALB with a Network Load Balancer Maintain the embedded NoSQL database with its replication service on the EC2 instances.
B.
Replace the ALB with a Network Load Balancer Migrate the embedded NoSQL database to Amazon DynamoDB by using AWS Database Migration Service (AWS DMS).
Answers

C.
Modify the Auto Scaling group to use EC2 instances across three Availability Zones. Maintain the embedded NoSQL database with its replication service on the EC2 instances.
Answers
C.
Modify the Auto Scaling group to use EC2 instances across three Availability Zones. Maintain the embedded NoSQL database with its replication service on the EC2 instances.
D.
Modify the Auto Scaling group to use EC2 instances across three Availability Zones. Migrate the embedded NoSQL database to Amazon DynamoDB by using AWS Database Migration Service (AWS DMS).
Answers
D.
Modify the Auto Scaling group to use EC2 instances across three Availability Zones. Migrate the embedded NoSQL database to Amazon DynamoDB by using AWS Database Migration Service (AWS DMS).
Suggested answer: D

Explanation:

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 across three 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.
