SCADA is an industrial automation system that:
It is widely used in:
Cloud solutions refer to internet-based platforms that:
Common cloud functions include:
When combined, SCADA and cloud systems create a smart industrial monitoring ecosystem:
| Parameter | Specification |
|---|---|
| System Type | Industrial automation + remote monitoring architecture |
| Core Function | Real-time data acquisition, monitoring, control, and analytics |
| Architecture Layers | Field devices → PLC/RTU → SCADA server → Cloud platform → User interface |
| Communication Protocols | Modbus (RTU/TCP), OPC UA, DNP3, MQTT, IEC 60870-5-104 |
| Data Acquisition Rate | Real-time to sub-second scanning (100 ms – several seconds depending on system) |
| Data Storage | Local historian (SCADA) + Cloud database (SQL/NoSQL time-series) |
| Cloud Deployment Models | SaaS, PaaS, Hybrid cloud, Private cloud |
| User Interface | HMI dashboards (desktop, web, mobile apps) |
| Connectivity | Ethernet, Wi-Fi, 4G/5G, VPN-secured internet |
| Latency | Local SCADA: milliseconds to seconds; Cloud: seconds to minutes (network dependent) |
| Scalability | High (supports multi-site and distributed systems) |
| Data Format | Time-series data, alarms/events, logs, telemetry |
| Security Features | Encryption (TLS/SSL), role-based access control, firewall, VPN, authentication (OAuth2/AD integration) |
| Alarm Management | Real-time alerts via SMS, email, push notifications |
| Redundancy | Hot standby servers, failover systems, backup databases |
| Integration Capability | PLCs, RTUs, IoT sensors, ERP/MES systems, APIs |
| Analytics Features | Trend analysis, predictive maintenance, AI/ML integration (cloud layer) |
| Operating Systems | Windows/Linux SCADA servers; cloud-agnostic platforms (AWS, Azure, GCP) |
| Response Time | HMI updates: <1–2 seconds typical |
| Reliability (Uptime) | 99.5% – 99.99% depending on architecture |
| Typical Applications | Water treatment, power plants, oil & gas, manufacturing, smart grids |
