Question 74
A company runs a legacy system on a single m4.2xlarge Amazon EC2 instance with Amazon EBS storage.
The EC2 instance runs both the web server and a self-managed Oracle database. A snapshot is made of the EBS volume every 12 hours, and an AMI was created from the fully configured EC2 instance.
A recent event that terminated the EC2 instance led to several hours of downtime. The application was successfully launched from the AMI, but the age of the EBS snapshot and the repair of the database resulted in the loss of 8 hours of data. The system was also down for 4 hours while the Systems Operators manually performed these processes.
What architectural changes will minimize downtime and reduce the chance of lost data?
