Most IoT applications are based on a cloud centric architecture. Data collected from sensors and devices are sent to a gateway, which then transfers it to a cloud based IoT platform. For a growing set of IoT applications, including those that are mission critical, latency sensitive, or with high reliability needs, a new architecture is needed. An edge based architecture, with processing performed at the device, or in a gateway near the devices, is now emerging. This article provides an overview of edge or fog computing, and lists some common use cases.
In the digital enterprise, the strategic fusion of IT, operations technology [OT], audio-video [AV] with transformational technologies (Cloud, Internet of Things, AI, analytics, edge processing) leads to richer customer experiences, business acceleration, and operational agility. This fusion leads to new innovation and digital transformation of the organization.
This article highlights the new roles and expectations of IT in an age of digital transformation.
