OPC UA: IIoT Enabler and Conqueror of the Cloud

摘要

Exchanging data between Industrial Internet of Things (IIoT) devices and the cloud presents a bewildering array of options. Cloud providers, Amazon Web Services, Microsoft Azure, Google IO, and many others each advocate for their own technique for IIoT data interchange. But operational technology (OT) applications have a very long life, and, in the fast-moving world of cloud IT, some solutions are likely to be orphaned. IIoT "standards" such as MQTT, AMQP, REST, and Kafka compete to serve as pipelines to move data across the network. At the same time, custom OT implementations from IIoT/edge/cloud software and hardware vendors can cause "vendor lock," limiting your choices and flexibility. The answer is OPC UA.
