System Design Deep Dive: Scaling a Hybrid Monitoring Service for Millions of Servers

Description

How do you monitor a distributed infrastructure where millions of servers span the globe. In this system design breakdown, we move beyond simple server logs to architect a fault-tolerant, massive-scale monitoring service capable of detecting hardware failures, application crashes, and network anomalies in real-time. We explore the evolution of the architecture, starting with the "Pull vs. Push" debate and landing on a Hybrid Hierarchical approach used to manage data center congestion. Whether you are preparing for a system design interview or building observable distributed systems, this video covers the critical trade-offs and component choices you need to know.
