The service makes setup, scaling, and cluster failure handling much simpler than in a self-managed cache deployment.</p> <p>In addition, through integration with Amazon CloudWatch, customers get enhanced visibility into the key performance statistics associated with their cache and can receive alarms if a part of their cache runs hot.</p>",
