Digital entrepreneurs today require a solution that seamlessly processes and handles real-time data. Edge computing and cloud computing are two effective methods that are emerging as the most suitable in the fast-paced digital landscape. Each has unique benefits, helping companies bring out the most out of their digital infrastructure.
This article explains the differences between edge computing and cloud computing and their advantages to your digital business strategy and data handling.
What Is Edge Computing?
Edge computing processes data closer to its source to minimize latency and maximize efficiency. This decentralized approach removes the need for transmitting huge amounts of data to remote data centers. Instead, processing occurs on the “edge” of the network, within devices (e.g. IoT devices), sensors, or gateways.
Transmitting data over long distances to a centralized data center can be slow and inefficient so edge computing is useful for organizations that want to avoid this and require real-time or near-real-time processing.
