Modern applications, often composed of multiple distributed components, require sophisticated health assessments to ensure overall availability and performance. Cloudflare has introduced Monitor Groups for its Load Balancing service, a feature that allows for the aggregation of multiple health monitors into a single entity, providing a comprehensive view of an application's health. This system enables users to define critical components, utilize observational probes, and apply quorum-based health assessments, ensuring that failover decisions are both intelligent and resilient. Health checks are conducted globally, leveraging Cloudflare's extensive network to prevent localized issues from causing unnecessary failovers. The Monitor Groups feature, initially available to Enterprise customers via API, is designed to enhance the accuracy of health checks without the need for custom aggregation services and will soon be accessible through the Cloudflare Dashboard for all users. This development is part of Cloudflare's ongoing efforts to simplify traffic management and enhance load balancing capabilities for complex applications.
