Cloud computing has quickly gained mainstream adoption... but fog computing has the potential to be just as dominant, if not more so.
What is Fog Computing?
Fog Computing (AKA edge computing) Fog computing places processes and resources at the edge of the cloud, often on network devices, while data remains stored in the cloud. This leads to faster processing times and fewer resources consumed. See Source
Traditional cloud computing, on the other hand, concentrates all applications and data in the cloud.
Fog computing is a response to some of the issues and problems encountered from regular cloud computing.
Cloud Computing Issue: Bandwidth
Transmitting and processing data requires bandwidth. The more data, the more bandwidth is needed.
Wireless networks that use the cloud have their own limitations. Data transmission simply isn’t fast enough.
Amplifying these problem is the growth of the Internet of Things, which will use more data and require much more bandwidth.
Fog Computing and the Internet of Things
By 2020, the number of “things” that are part of the IoT may reach up to 50 billion. That’s a lot of data being generated. See Source
Current cloud computing models can’t keep up with the amount of bandwidth that will be needed.
Fog computing goes around the internet entirely by processing data locally.
Fogging basically helps cloud systems by easing the burden of processing data.
Fog computing can also be used in other areas.
Fog Computing Uses
Smart Cities Fog computing helps collect data on city activities from traffic to utilities, ensuring everything is running efficiently. See Source
2TB 2TB 2TB 2TB Air Travel A single engine on a Boeing 747 generates 0.5TB of data. Fog computing can process that data locally and send only the most important bits of information to those who need to see it. See Source
Wearable Technology Wearables with virtual interfaces need to process their environment locally to aid the user. Fog computing allows for that processing to happen almost immediately, improving the user experience.
