الأنظمة الفورية
Some jobs can't wait a second: live location, instant notifications, a kitchen display or sensor data from a device. With push, WebSockets and event-driven flows we move the data without delay.
Some jobs can't wait a second
Where a courier is, an order landing in a kitchen, a sensor reading from a device — here, delay is a defect.
Live location & tracking
The location of a courier, a vehicle or a field team updates on the map within seconds.
Instant notification & push
The moment an event happens, the right notification reaches the right person — not minutes later, that instant.
Real-time screen updates
A register screen, a kitchen display or a management dashboard reflects what's happening behind it without a page reload.
Device & sensor data streaming
A reading from a meter or sensor lands in the system before a human looks, and a threshold breach is caught instantly.
Event-driven architecture & queues
When an event happens, more than one system may need to react; a message queue puts that reaction in a reliable order.
Live streaming & synchronization
Playback state on one device stays in sync with a remote control on another, without lag.
Choosing the right channel comes before moving the right data
Real-time isn't one technology; it's a channel choice that changes with the shape of the work. We use WebSocket/SignalR to update a user interface instantly, push notifications (FCM) to guarantee reaching a mobile device even when it's asleep, and a message queue (RabbitMQ, Redis) when more than one system needs to react to an event. The wrong channel choice either adds needless load or delivers data late — neither is acceptable in a real-time system.
We haven't tried these channels in isolation; we've built them working together inside our 46 sector products. In a logistics product, live location streams over WebSocket, the same product pushes an alert for a delayed delivery, and a lagging event behind the scenes drops into a queue and retries — all three running at once, with the same discipline.
- WebSocket/SignalR: instant UI updates
- Push (FCM): reaches even a sleeping device
- Message queue: reliable, ordered event response
- Three channels working together across 46 products
Real-time at work in real scenarios
Logistics: live tracking of couriers and fleet
A courier's, driver's or field team's work happens on the road, not at a desk. The day's shipments are sequenced into a route, and every step — departed, delivered, collected — is recorded instantly from the phone; the control screen watches the whole field live over SignalR. This is the shared backbone of our five logistics-vertical products.
- Live location updates over SignalR
- Every step recorded instantly from the phone
- The whole field watched live from control
VideoCaster: lag-free sync across devices
VideoCaster is our published mobile app that casts video from phone and web to the TV, with queue and remote-control support. A 'next video' command sent from one device executes instantly on another; playback state and queue order stay continuously in sync across devices — a tangible, consumer-facing example of real-time at work.
- Remote-control commands deliver without lag
- Playback state stays in sync across devices
- Queue order updates live
Facility management: notification the moment a threshold is crossed
Meter and sensor data is collected continuously via an edge gateway; when a value crosses a threshold, an outage occurs, or an anomaly appears, a notification fires simultaneously by SMS, email and on the dashboard. The manager sees the problem on the dashboard that instant, not in a report the next day.
- Instant notification over three channels on threshold breach
- Continuous streaming of sensor data
- A problem shows on the dashboard without waiting for a report
How we build a real-time system
Channel selection
We decide together which of WebSocket/SignalR, push (FCM) or a message queue is the right tool, based on the shape of the work.
Event model & queue design
We define which event triggers whom, and build a reliable, ordered event flow on RabbitMQ/Redis.
Scaling & reconnection
We design upfront what happens when a connection drops (reconnection, catching up on missed events) and test it under load.
Monitoring & go-live
We monitor latency and connection metrics, validate under real load in production, then continue under SLA maintenance.
Other sectors where real-time is at work
Beyond the three examples above, the same discipline takes a different shape in other products of ours.
HoReCa: kitchen display (KDS)
An order taken at the register drops onto the kitchen display instantly, without paper; prep order is managed from there.
Private security: incident logging
An incident logged in the field appears on the manager's dashboard at once, with its photo and location.
Public sector & facility: work-order alerts
A citizen request drops to the field as a work order at once; the office is notified the instant it's completed.
Care: shift changes
A change made to a roster appears at once to the affected caregiver or security officer — no phone traffic needed.
