Content Delivery Network (CDN)
A system of distributed network elements that delivery pages and other web content to a user, based on the geographic locations of the user, the origin of the webpage and a content delivery server.
Edge Computing
A distributed computing paradigm that brings computation and data storage closer to the location where it is needed, to improve response times and save bandwidth.
Fog Computing
An architecture that uses edge devices to carry out a substantial amount of computation, storage, and communication locally and routed over the internet backbone.
Edge Device
A device that provides an entry point into enterprise or service provider core networks. Examples include routers, routing switches, integrated access devices, multiplexers, and a variety of metropolitan area network (MAN) and wide area network (WAN) access devices.
Micro Data Center
A smaller or containerized data center architecture that's designed for computer workloads not requiring traditional data center space.
Distributed Cloud
A cloud model that allows public cloud services to be distributed to different physical locations, while the operation, governance, updates, and evolution of the services remain the responsibility of the originating public cloud provider.
Edge Server
A server placed strategically within a network to improve network service delivery by providing localized computing, caching, and processing.
Edge Analytics
The analysis of data that takes place directly at or near the sensor, network switch, or other device that is producing the data.
Service Chaining
The process of creating a chain of advanced network services that include physical and virtualized security, load balancing, and network functions.
Internet of Things (IoT)
The interconnection via the internet of computing devices embedded in everyday objects, enabling them to send and receive data.
Edge Data Center
A small data center facility located close to the edge of a network that delivers cloud computing resources and cached content to end users.
Latency
The delay before a transfer of data begins following an instruction for its transfer. Lower in edge computing compared to cloud computing due to proximity to data source.
Bandwidth
The maximum rate of data transfer across a given path. Edge computing can help reduce the bandwidth needs by processing data locally.
Cloud Computing
A model for enabling ubiquitous access to a shared pool of configurable computing resources that can be rapidly provisioned with minimal management effort.
Mobile Edge Computing
An architecture that allows cloud computing capabilities and an IT service environment to be at the edge of the cellular network.
Response Time
The time taken for a system to respond to an instruction. Edge computing aims to minimize response time for improved performance.
Network Functions Virtualization (NFV)
A network architecture concept that uses the technologies of IT virtualization to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create communication services.
Edge Node
A network component that offers an interface to another network, one of numerous endpoints or points of presence (PoPs) in a content delivery network (CDN), or a delivery point for client applications.
Smart Grid
An electricity supply network that uses digital communications technology to detect and react to local changes in usage.
Cloudlet
A small-scale data center or cluster of computers designed to quickly provide cloud computing services to mobile devices with lower latency.
