What does the OCI “Health Checks” feature allow you to do?

The OCI “Health Checks” feature is designed specifically to monitor the health of application endpoints and ensure that only healthy instances are serving traffic. When an application is deployed in Oracle Cloud Infrastructure, maintaining high availability and performance is crucial. The health checks periodically assess the status of application endpoints, allowing the system to detect if an instance is unresponsive or unhealthy.

When an unhealthy instance is identified, the health check can initiate actions to automatically remove that instance from the load balancer's pool. This helps to improve overall application reliability, as traffic will only be directed to instances that are confirmed to be functioning correctly. This automated management of instance health is vital for applications that need to maintain consistent availability and performance, minimizing downtime and optimizing resource utilization.

Other options such as monitoring user login activity, tracking data usage in real time, and encrypting application data do not align with the specific function of the Health Checks feature, which is focused on the operational health of application instances rather than user activity or data management.
