Topic 1 Question 69
A company is running a business-critical web application on Amazon EC2 instances behind an Application Load Balancer. The EC2 instances are in an Auto Scaling group. The application uses an Amazon Aurora PostgreSQL database that is deployed in a single Availability Zone. The company wants the application to be highly available with minimum downtime and minimum loss of data. Which solution will meet these requirements with the LEAST operational effort?
Place the EC2 instances in different AWS Regions. Use Amazon Route 53 health checks to redirect traffic. Use Aurora PostgreSQL Cross-Region Replication.
Configure the Auto Scaling group to use multiple Availability Zones. Configure the database as Multi-AZ. Configure an Amazon RDS Proxy instance for the database.
Configure the Auto Scaling group to use one Availability Zone. Generate hourly snapshots of the database. Recover the database from the snapshots in the event of a failure.
Configure the Auto Scaling group to use multiple AWS Regions. Write the data from the application to Amazon S3. Use S3 Event Notifications to launch an AWS Lambda function to write the data to the database.

By configuring the Auto Scaling group to use multiple Availability Zones, the application will be able to continue running even if one Availability Zone goes down. Configuring the database as Multi-AZ will also ensure that the database remains available in the event of a failure in one Availability Zone. Using an Amazon RDS Proxy instance for the database will allow the application to automatically route traffic to healthy database instances, further increasing the availability of the application. This solution will meet the requirements for high availability with minimal operational effort.
