Content Delivery Networks
Master how CDNs reduce latency with edge caching, invalidation, push vs pull delivery, edge computing, and CDN security.
What You Will Learn
Map the control plane and data plane boundaries behind Content Delivery Networks.
Reason about latency, retries, health signals, and failure isolation at service edges.
Choose where policy lives: clients, sidecars, gateways, registries, or centralized controllers.
Balance operational simplicity against flexibility, security, and multi-region behavior.
Key Decisions
Where should Content Delivery Networks sit in the request path or service control plane?
Which state must be strongly consistent, and which state can tolerate eventual propagation?
How do you observe health, policy drift, and partial failure without creating new bottlenecks?
What changes when the platform expands to multi-region or multi-tenant operation?
