Question

IoT hydrant sensors can preprocess readings at the edge or ship raw streams centrally. When is edge processing the cost-sensible architecture choice?

Accepted Answer

When edge filtering meaningfully cuts costly central egress, storage, or latency—not as a cargo-cult default — Edge processing isn't a trophy—it's a savings play when it chops expensive central data hauling or latency. If it doesn't buy you that, keep the brains in the Region and skip the cargo cult.

Answer

Always process at the edge even when it increases device cost without reducing egress or latency pain

Answer

Never use edge processing because Regions cannot receive filtered data

Answer

Only when AWS Outposts is unavailable in every firehouse
