Edge nodes are computing devices or servers located at the edge of a network, near data sources or end users, and are designed to perform data processing, storage, and service delivery with low latency and reduced bandwidth to central cloud. They can take the form of industrial gateways, micro data centers, edge servers deployed at regional points of presence, or network appliances. Some include accelerators for AI inference or security, and they are capable of running containers or lightweight virtual machines.

Typical functions include data pre-processing, filtering and aggregation, protocol translation, caching, and running applications close to devices, such as edge AI, video analytics, or IoT gateways.

Edge nodes are managed through edge orchestration platforms that provision, monitor, and update software across many nodes, and may operate as part of a hierarchical architecture with devices at the edge, regional nodes, and central cloud.

Use cases span industrial automation, smart cities, autonomous vehicles and drones, augmented reality, healthcare monitoring, and content delivery networks that cache content closer to users.

Challenges include security and physical risk, reliability in remote locations, heterogeneity of hardware and software, interoperability across vendors, and energy constraints. Effective governance typically relies on strong access control, encryption, secure boot, and regular software updates.

In relation to related concepts, edge nodes complement cloud resources and are a core element of edge computing; they are closely linked to fog computing and to content delivery networks that extend caching and processing toward the network edge. See also: Edge computing, Fog computing, CDN.
