Fog Computing vs Edge Computing Deployment in Higher Education

New forms of computing infrastructure – fog computing and edge computing – are entering IT conversations in higher education as universities expand Internet of Things applications on their campuses.

Many campuses already incorporate a variety of cloud computing solutions, using cloud’s flexible scalability to easily control and adapt campus networking to fit specific needs.

In fact, experts forecast the market for cloud computing on campus to increase by 26 percent in 2021.

Cloud computing can be great for more robust data storage, computing and security. Where fog computing versus edge computing comes into play will depend on the needs of each campus.

What Is Fog Computing?

Fog computing is an emerging structure for computing, storing and securing information beneath the cloud layer. It allows these actions to be spread more evenly across the network and not just on a central node.

Fog computing versus cloud computing requires information to be sent back and forth from IoT devices to a central system, to store and compute data on nodes closer to the data source.

Less space to travel means a significant reduction in latency, in some cases from 100 milliseconds to less than one.

For higher education, fog computing could be a powerful support for applications requiring faster data speeds, such as artificial intelligence, mixed reality devices, high-performance computing and even 5G network integratio n.

According to Cisco, which coined the term in 2014, fog computing is “a standard that defines how edge computing should work, and it facilitates the operation of compute, storage and networking services between end devices and cloud computing data centers.”

On campuses, fog computing could help universities i nstall smart building infrastructure, including in-ground vehicle detection for parking spaces and smarter, more secure entry systems.

Some of the smart city applications for fog computing could also be applied to campuses. This could include monitoring traffic on roads running through and around campus and using real-time security cameras.

Some universities have already started to research applications that could benefit from fog computing, including autonomous vehicles, agriculture technology and remote surgery.

At the University of Arizona, Marwan Krunz, a professor in the department of electrical and computer engineering, is leading a team funded by 15 technology companies to study the applications of fog computing across industries, according to EurekaAlert.

Meanwhile, at Duke University, experts believe fog computing could potentially lead to responsive augmented reality, or holograms, on campus.

“Fog offers a natural chokepoint for reducing the resources consumed on mobile nodes in multi-user settings, as well as a natural point for making those experiences more intelligent,” Maria Gorlatova, a Duke electrical and computer engineering professor, said at Fog World Congress this year.

What is Edge Computing?

With edge networks, data storage and computing are kept close to the device, application or human that produces the data being handled.

For IoT-connected devices that generate large quantities of data, this can be extremely helpful in cutting down the time it would take to send data back and forth to a cloud network.

Edge computing has already started to improve a number of higher education functions, from network traffic management to the quality of the end-user experience.

In 2017, the University of Notre Dame and Nokia partnered to bring multi-access edge computing to the university’s Compton Ice Arena.

Using a combination of Wi-Fi access points, Nokia’s MEC platform and its AirFrame server, the stadium was able to stream video on four separate platforms within a 500-millisecond delay of each other.

Recently, Carnegie Mellon University and Microsoft agreed to collaborate on research around edge computing.

The technology giant is giving Carnegie Mellon edge computing products, including Azure Data Box Edge, Azure Stack and Microsoft Azure credits. The hardware will be powered by Intel Xeon Scalable processors.

These new tools will go to Carnegie Mellon’s designated edge computing laboratory. There, students and faculty will push Microsoft’s equipment to see what their capabilities are.

Fog Computing vs. Edge Computing: What Is the Difference?

If it sounds like edge computing and fog computing are similar, it is because they are. However, while fog computing always uses edge computing, the opposite is not always true.

The OpenFog Consortium, a global partnership working to improve fog applications founded by Cisco, Dell, Intel, Microsoft, Princeton University and ARM, a United Kingdom chip company, notes a few key differences:
