What is Edge Computing?
Edge computing refers to a distributed computing model that brings computation and data storage closer to the devices or sensors that generate them, rather than relying solely on centralized cloud infrastructure. In other words, edge computing aims to move computing resources and intelligence closer to the “edge” of the network, where data is generated and consumed, rather than relying on a centralized data center to process and analyse data.
The primary motivation for edge computing is to reduce the latency and bandwidth constraints associated with transmitting large amounts of data to a centralized cloud infrastructure for processing and analysis. By processing data closer to where it is generated, edge computing can reduce network congestion, lower latency, and improve overall performance.
