Real-time messaging over measured low-latency paths
Move live operational signals from many writers to downstream processors without adding a storage layer. Live transport, not durable ingestion.
FastPubSub is a managed global service broker for real-time signal transport. Operate globally across the planet or keep processing in a single region by configuration.
Telemetry-like events often come from many nodes and must reach processors quickly for immediate decisions.
Direct routes can degrade over time, adding avoidable delay for live monitoring and control loops.
When the signal value is time-sensitive, extra persistence layers can increase end-to-end latency.
Relays route around congestion and deliver live signals over better paths available at that moment.
FastPubSub transports events in real time and avoids durable storage overhead by design.
Many-writer traffic can be collected and forwarded to processors across regions with stable latency.
Kafka, NATS, and RabbitMQ are software platforms for durable and brokered workflows. FastPubSub is a managed live-delivery service.
Use FastPubSub when signal value depends on low-latency delivery, not on storage and replay.
