Final answer:
A suitable solution for implementing a pilot light DR strategy for the self-contained on-premises application is to replicate it in the cloud using a minimal infrastructure.
Step-by-step explanation:
A pilot light disaster recovery (DR) strategy is an approach where a scaled-down version of the infrastructure is constantly running in the cloud. In case of a disaster, the application can be quickly scaled up to meet the demand. In this case, since the application is self-contained and doesn't need to access any databases, a suitable solution for implementing a pilot light DR strategy would be to replicate the on-premises application in the cloud, using a minimal infrastructure that includes only the essential components needed to run the application.
For example, you can set up a few Amazon EC2 instances (virtual servers) in the cloud that host the self-contained application. These instances can be kept in a stopped or low-powered state, serving as the pilot light. When a disaster occurs, you can quickly launch more EC2 instances and redirect traffic to them, scaling up the infrastructure as needed.
By using a pilot light DR strategy for this self-contained on-premises application, the company can reduce downtime and maintain business continuity in case of a disaster.
