Not a competition
Public cloud is excellent at elastic compute, managed databases and global services. Edge infrastructure is excellent at being close to users. Most modern applications benefit from both — the question is which parts go where.
Questions to ask about each component
- How sensitive is it to latency? Interactive features, real-time media and gaming benefit from the edge.
- How much data does it move? Video delivery and data aggregation are cheaper when traffic stays local.
- Does data need to stay in a region? Some workloads have locality or compliance needs.
- How variable is demand? Highly elastic workloads fit the cloud well.
Common patterns
- CDN-style delivery: Origins in the cloud, caches at the edge.
- Real-time apps: Session handling at the edge, persistence in the cloud.
- IoT and video analytics: Pre-processing at the edge, long-term storage and ML training in the cloud.
- Gaming: Match servers at the edge, accounts and economy in the cloud.
Connecting the two
The weak point in many hybrid designs is the network between edge and cloud. Running that traffic over the public internet adds variability. Private paths — such as Peer1IX Data Center to Cloud — keep it predictable.
Start small
Pick one latency-sensitive component, move it to an edge site in your busiest region, and measure the difference. Use the results to decide where else edge placement pays off.
