Flow Architectures

Distributed & Scalable / Flow Architectures

Integrate systems around data in motion — publish state changes as continuous streams and let consumers subscribe, event-first, in real time.

01
Data in motionEvents stream continuously instead of sitting at rest waiting to be queried.
02
Event-first integrationPublish changes continuously; consumers subscribe rather than calling on demand.
03
Streaming pipelinesA continuous graph transforms, enriches, and routes events — not a scheduled job.
04
Subscribe, don't wireNew consumers tap an existing stream; no bespoke point-to-point links.
⚑

Instead of asking a system for data when you need it, receive its changes continuously and react. Integrate as data moves, not on a schedule.

Real-timeWarehouse publishes 'ShipmentUpdated'; transport and customer systems react within seconds.
Add a tapA new analytics team subscribes to the existing stream — no new nightly job.
batch:  A --nightly--> B  (point-to-point, delayed)
flow:   A --stream--> [pipeline: enrich/route] --> B, C, D
new consumer -> subscribe to existing stream (no new wiring)
