IoT can exist without edge devices or edge computing. But they don’t have to be connected.Ĭlouds can exist without the Internet of Things (IoT) or edge devices. Cloud, edge, and IoTl can all be connected. Internet of Things (IoT) refers to any system of physical devices that receive and transfer data over wireless networks with limited human intervention. The sheer volume of data collected is too much to send-unaltered-to a cloud. The rate at which a decision needs to be made doesn’t allow for the lag that would normally take place as data is collected by an edge device, transferred to a central cloud without modification, and then processed before a decision is sent back to the edge device for execution. Collecting data at the edge of a network and transferring it to a cloud with minimal (if any) modification is not edge computing-it’s just networking.īut, if that data is collected and processed at the edge, then it’s edge computing.Įdge computing is separate from clouds for 2 main reasons: Edge computing is also an act the act of running workloads on edge devices.Īn edge (location) is not the same thing as edge computing (action).Cloud computing is an act the act of running workloads in a cloud.They are physical environments made up of hardware outside a datacenter. Edges are also places where data is collected.They are software-defined environments created by datacenters or server farms. Clouds are places where data can be stored or applications can run.Here’s one model for thinking about cloud and edge: Although edge and cloud are related ideas, they’re also different.Įdge devices can contribute to a cloud, if the storage and computing capabilities provided by those devices at the endpoints of a network are abstracted, pooled, and shared across a network-essentially becoming part of a larger cloud infrastructure.Įdge computing is distinct from cloud computing by definition, since it describes workloads that happen in remote locations that are outside of what are normally considered cloud environment-closer to where a physical device or data source actually exists. There isn’t always a clear line where one ends and the other begins.
