Edge computing is a distributed computing paradigm that brings data, compute, storage, and applications closer to the user or the data source. It has been developed to address the challenges posed by traditional cloud computing, such as latency, bandwidth, and cost. Edge computing enables processing of data at the source, so it can be analyzed and acted upon in real-time, without having to send it to the cloud or a data center. This allows for faster, more efficient and secure data processing.
The main advantages of edge computing are reduced latency, improved data security, and lower costs. By bringing computation closer to the edge of the network, edge computing reduces the need to send data to the cloud, which increases bandwidth and reduces latency. Additionally, edge computing enables data to be stored and processed more securely, since data never leaves the edge of the network. Finally, edge computing can be cheaper than traditional cloud computing, since it reduces the need for cloud services and the associated costs.
Edge computing has a wide range of applications in different industries. For example, in the automotive industry, edge computing is used to provide real-time navigation and autonomous driving.
