edgecompute

Edge computing, sometimes written as edgecompute, is a distributed computing paradigm that processes data near its source rather than in centralized data centers. By running applications at or close to sensors, devices, and users, edge computing aims to reduce latency, lower bandwidth use, improve privacy, and enable offline operation for connected systems.

Core components include edge devices such as sensors and cameras, edge gateways or micro data centers located at the network edge, and edge orchestration platforms that deploy and manage software across at scale. Communication relies on fast networks (for example 5G, Ethernet) to connect devices to edge nodes, which may perform data filtering, aggregation, or AI inference before sending results to the cloud or to other devices.

Common deployment models are on-premises edge at the customer site, near-edge facilities operated by network providers or service providers, and far-edge data centers located at regional points of presence. Use cases include autonomous vehicles, industrial automation, smart cities, retail analytics, video surveillance, augmented reality, and content delivery networks.

Benefits include lower latency, reduced bandwidth, improved data privacy, and resilience in situations with intermittent connectivity. Challenges involve security and privacy at many devices, diverse hardware and software environments, lifecycle management, interoperability, and energy and maintenance costs.

Edge computing complements cloud computing by moving time-sensitive processing closer to data sources while still integrating with centralized services for storage and analytics. It overlaps with fog computing and is a core element of mobile edge computing (MEC) initiatives in telecom networks.
