Fog Computing – The Bridge Between Edge and Cloud
You've heard of cloud computing. But what about fog? It's the middle layer that brings computation closer to you, reducing latency and making IoT devices smarter.
HISTORY / ORIGIN
The term "fog computing" was first developed by Cisco in 2012 to address the challenges of IoT applications in conventional Cloud computing. In 2015, Cisco Systems, ARM Holdings, Dell, Intel, Microsoft, and Princeton University founded the OpenFog Consortium. Fog computing is an architecture that uses edge devices to carry out a substantial amount of computation, storage, and communication locally.
TYPES OF FOG COMPUTING ARCHITECTURES
Fog Nodes – Intermediate devices that process data between edge and cloud.
Edge Devices – Sensors and IoT devices at the network edge.
Cloud Integration – For long-term storage and non-latency-aware processing.
MATERIALS / KEY FEATURES
Heterogeneity – A highly virtualized platform providing storage, networking, and computing services.
Distributed computing – Computation takes place in edge devices and fog nodes.
Low latency – Processes data closer to the source for faster response.
BENEFITS / WHY CHOOSE FOG COMPUTING
✅ Reduced latency – Faster processing for real-time applications.
✅ Efficient data handling – Reduces bandwidth usage to the cloud.
✅ Better quality of service – For end users.
✅ Handles IoT scale – Supports highly distributed sensors and devices.
✅ Local processing – Keeps sensitive data closer to the source.
CARE TIPS / USAGE TIPS
Understand the difference – Fog computing adds an intermediate layer between edge and cloud, while edge computing processes data directly on devices.
Consider latency needs – Real-time applications benefit most from fog.
Plan for scalability – As IoT grows, fog architectures become more important.
Security matters – Distributed computing requires robust security.
