Why do my WebAssembly modules go dark the moment they enter production?
機会
WASM is now a real deployment target at the edge, in serverless, and in plugin sandboxes. Container workloads have had OpenTelemetry, Prometheus, and structured logging for years; WASM workloads running under WASIp3 hosts do not emit guest-level spans by default and require deliberate instrumentation wiring that most frameworks omit. Stack traces in production failures reduce to binary addresses because DWARF debug info is stripped at build time and source maps do not survive most deployment pipelines. Operators cannot set up the same alerting and dashboards they use for containers because there is no standard way to get telemetry out of a running WASM module without modifying the guest code itself.
重要な理由
Without native production observability, WASM cannot displace containers in any workload where on-call engineers need to diagnose a live incident.
機会をどう評価するか
Opportunity Scoreは測定値ではなく、私自身の見解です。どれほど痛みを伴うか、どれほど頻繁に影響を与えるか、そして今日時点で解決策がいかに少ないか。スコアが高いほど、構築する価値が高いと私は考えています。
それが現れたときにどれほどの痛みをもたらすか。
実際にどれほど頻繁に人々がそれに直面するか。
今日時点で、それに対する優れたツールがいかに少ないか。
