V8 isolates win on speed; microVMs win on isolation and native code.
WebAssembly's isolation model makes it the default for edge computing's multi-tenant workloads.
Eliminate round-trips by running personalization logic where users are, not where servers live.
Consumption-based pricing is the only model that tracks how edge compute actually behaves.
Data locality now means compliance, not just speed, and hand-wired regions can't scale.
Fixing cold starts requires matching each remedy to the right layer of the problem.
Single-threaded compute with built-in storage solves edge consistency without sacrificing speed.
Edge workers slash latency for APIs, but only when your data lives at the edge too.
