Replaying dead-letter messages across Azure, AWS and GCP, and saying "verification required" when it can't be proven

说明与用途

ServiceHub 管理 Azure、AWS 和 GCP 的死信队列消息，提供按失败原因分组、重放预览、成功验证和不可变恢复账本。

问题

When queues back up, messages land in dead‑letter queues and teams instinctively replay them, but they lack visibility into why failures occurred, whether the root cause is fixed, who replayed what, and whether the replay succeeded.

结果

ServiceHub enables teams to understand failure reasons, safely replay messages with preview gates, verify replay success where possible, automate replay with safety mechanisms, and maintain an immutable ledger of recoveries.

工作流

• 1. View dead‑letter queues per cloud; failures are grouped by reason.
• 2. Press "Look now" for AWS/GCP to read up to 100 messages and store them locally.
• 3. Click "Replay" on a message or "Replay All" for a group; ServiceHub shows a proposal with scope, sample, risk, policy, and stop condition.
• 4. If all checks pass, the replay is executed; otherwise it is blocked.
• 5. For Azure, ServiceHub confirms whether replayed messages stayed out of the dead‑letter queue; for AWS/GCP it marks the replay as "verification required".
• 6. Auto Replay rules are applied per failure signature, with circuit breakers, emergency stops, and back‑off if recent replays failed.
• 7. All recoveries are written to a hash‑chained ledger visible in the Advanced view.

"every replay, whether a person clicks it or the Agent does it, goes through one gate. Before anything is sent it shows a proposal: scope, a sample, the risk, the policy and the stop condition."

来源

"Azure can confirm whether a replayed message stayed out of the dead‑letter queue. AWS and GCP can't, without extra infrastructure."

来源

"The Agent replays on its own only for a failure signature it has earned trust on, per signature, not globally."
