Explaining Edge Computing

Edge computing definitions and concepts. This non-technical video focuses on edge computing and cloud computing, as well as edge computing and the deployment of vision recognition and other AI applications. Also introduced are mesh networks, SBC (single board computer) edge hardware, and fog computing.

Its like being back at school, but fun. 10 minutes of edutainment. No filler, just what you need to know without being treat like a child or an expert. It's a YES from me

These videos remind me of the Open University courses that would broadcast through the night on BBC2. They are very well put together, you are a great teacher.

Effectively it seems like a reversion to how things used to operate, local servers handling the bulk of processing.

20 years ago, with limited internet connection, most security and manufacturing monitoring services were done at a local point with a secondary feed to an off-site cloud accessible server.

Seems like it took all of this time for people to realize that local hosting was actually the better option.

I have been watching this channel for 10 years now, and this guy hasn't changed a bit! I love it!

It amazes me, how fanatic we are to give away our personal data, to get the IN thing, IOT devices will be the most intrusive items for data gathering there is, and how many apps thst you dowload for your Smart phones want access to your. pictures, contacts, files, camera, microphone etc.

Getting up at 6am to start my Sunday with your videos isn't fun, but definitely worth it, thanks Chris.

Thank you for adding much-needed to detail to this fascinating subject ! As everyone below is saying, it inevitably is re-inventing the wheel, which started in the late nineteenth century with the growth in use of electrical telegraphy. Operators soon had to start recording messages received, on paper tape for later onward transmission. As people below are saying, certainly during my time in the computer business ( from the late 1960s to 2000 ), centralised and localised processing regularly came in and out of favour as quickly as the changing styles of clothing worn by the operators ! The briefing that you're giving us in this video is certainly bringing us "up-to-date" with "where we're at" currently - much-needed as systems become much cleverer ! THANK YOU for this - and keep telling us !

I have been researching on edge clouds since 2014 and I commend (and approve) your work in this video. Not even many researchers have figured that "Fog" is a marketing term by CISCO to push their products. Edge, Fog, Mist, Mobile Edge, Mobile Access Edge, etc. etc. Names may be many but you hit the nail right on its head with the basic explanation of the concept. Job well done!

[marccarter]

Thanks, Christopher! Watching the programs you make, in particular, the ones on your AMD build, gave me the confidence to build my own AMD system. I love learning from you, please keep teaching.

Excellent video. I'm glad everything is explained very clearly. Thank you!

Proud Nottingam Business School alumni. I remember your lectures on cloud computing eons before it was mainstream.

[JuanMulford]

Probably the best explanation on YouTube. Subscribed.

Mainframes, then PCs, then the cloud and now edge computing. Back and forth it goes!

[geographicaloddity]

Process control instruments have been moving in this direction for many years with I/O that can be connected to instrumentation nearby and mounted directly on or near the equipment. The I/O communicates to the PLC via Ethernet.
Now, we have highly accurate devices with built in diagnostics that connect to the PLC over Ethernet. Previously, multiple wires for analog and discrete signals would have been required to send the information for mass flow, density, temerature, flow total and device health from a coriolis meter and now, using Ethernet IP or Modbus TCP, all of that information and more is sent directly to the PLC, HMI, or process historian.
I think the key to acceptance of SBC devices on the plant/factory floor will be availability of "open" standards like OPC, EthernetIP and ModbusTCP.

Thanks for another thought provoking video.

interesting switchback, to see compute move away from the cloud to augment efficiency, you explain things well, thanks!!

[peegee]

I just shared this with my team and manager to breach the informational gap. Great work, thank you soo much!

[JamieWhitehorn]

Another great video of just the right length. No waffle, no banter, just the information you need to understand the concept.

It makes me wonder, is this process cyclic? 50 years ago compute power was expensive so processing was centralised with mainframes and dumb terminals. Then PCs change the landscape with cheap processing and we de-centralised. Then we upped the amount of processing we needed to handle the vast amounts of data we are now collecting so the Cloud was born and we centralised again. Now we've got dedicated devices like VPUs and pre-trained neural nets that can offload the processing and a limited resource of bandwidth, so we're decentralising again. I wonder if we "fix" the bandwidth problem will we centralise again ...😀

Thanks for another exciting show. Edge computing is much needed when speed and response time is important.

[bartniaux]

Thanks for a clear explanation of Edge computing Chris. As SBC processor are getting more processing power, it makes sense to using the Edge environment. This means also that we require additional interrupt capabilities for real-time processing on the SBCs.

I'm glad I found you. Great channel, exactly what I need !
