CASE ANALYSIS
Scenario
A service provider needs to serve cached content globally through edge nodes with mid-tier caches for origin offload and failover.
Key decisions
- Placed a global load balancer to distribute traffic across two edge aggregation switches
- Used two mid-tier cache nodes for redundancy and failover between edge and origin
- Segmented edge, distribution, and core tiers for scalable operations
When to reuse this
When modeling CDN cache hierarchy with failover and tiered service-provider infrastructure.
