Fog Computing
What is it?
Fog Computing is a concept first introduced by Cisco in 2014. It has gained widespread attention as more and more devices connect to the internet and generate massive amounts of data, making it increasingly difficult for traditional cloud computing alone to handle all processing needs. Fog computing can be seen as an extension of cloud computing—its key idea is to shift data processing and storage from centralized data centers to nodes closer to end devices. In other words, fog computing does not replace the cloud but adds an intermediate layer between the cloud and endpoint devices. This architecture helps reduce data transmission latency and improves real-time responsiveness, making it especially valuable in applications such as the Internet of Things (IoT) and smart cities.
