Fog computing is a system-level horizontal architecture that distributes resources and services of computing, storage, control and networking anywhere along the continuum from Cloud to Things. It is a:
- Horizontal architecture: Support multiple industry verticals and application domains, delivering intelligence and services to users and business
- Cloud-to-Thing continuum of services: Enable services and applications to be distributed closer to Things, and anywhere along the continuum between Cloud and Things
- System-level: Extend from the Things, over the network edges, through the Cloud, and across multiple protocol layers – not just radio systems, not just a specific protocol layer, not just at one part of an end-to-end system, but a system spanning between the Things and the Cloud
邊緣計算+IoT雲平台，物聯網既要能上天，還要接地氣！
「邊緣計算」是在靠近物或數據源頭的網路邊緣側，融合網路、計算、儲存、應用核心能力的開放平台，就近提供邊緣智慧服務。需要強調的是，最新出現的「邊緣計算」設備，並不是傳統的網路閘道，或者控制器換個名稱「濫竽充數」，而是需要滿足3個必備能力：採集邊緣數據、智慧的運算能力和可操作的決策回饋。
什麼是邊緣計算(Edge computing)？ 邊緣計算的解釋和三種類型
由於產生數據的事物和人通常不在雲端，因此我們需要通過許多形式的在物聯網(IoT)解決方案架構的邊緣處的計算來補充雲計算。
就物聯網(IoT)設備的尺寸和功率來說，鄰近計算(Proximity Computing)平衡了回應事件的即時性，與回應事件的成本兩者之間的關係。
