Alert Bridge
Fault-tolerant webhook router, alert deduplication, and distributed dispatch engine.
Production Benchmarks & Targets
Deduplication
100% Windowed
Dynamic sliding-window hash filter
Dispatch Latency
<60ms
Parallel async fan-out
Retry Backoff
Exponential
Jitter-protected delivery retry
System Architecture Invariants
- •Sliding-window hash deduplication in Redis to prevent alert storms from overwhelming incident response teams.
- •Asynchronous fan-out architecture routing unified alerts to Slack, Discord, Telegram, and PagerDuty.
- •Token-bucket rate limiter per outgoing provider channel to strictly respect downstream platform API limits.
Security & Threat Mitigations
- •Inbound token authentication and encrypted environment variable secrets.
- •Strict egress payload sanitization stripping sensitive internal stack traces before dispatch.
Problem & System Constraints
During cascading outages, microservices generate thousands of identical alert webhooks simultaneously, leading to rate limiting and alert fatigue.
Architectural Solution
Alert Bridge acts as an intelligent intermediary. It aggregates, deduplicates, transforms, and dispatches incident webhooks across multiple notification channels with rate-limiting and jittered exponential retries.
