According to the proactive policy, we should proactively respond to a request if it is leading towards a failure. We can use techniques such as timeout, caching, and health checks to proactively monitor application performance, and use them to proactively respond in the event of failure.

• Timeout: If a request takes more than the usual time, it ends the request
• Caching: Caches previous responses and uses them for future requests
• Health checks: Monitor the application's performance and invokes alerts in the event of failure
