Raspberry Pi Cluster Ep 1 - Introduction to Clustering

In this video, I introduce the concept of Raspberry Pi clustering, and cluster computing in general. Technology like Beowulf clusters and Kubernetes has made it easy to build clusters using off-the-shelf components.

Great explanation. I appreciate that you explained simple things like what a LAMP stack is, instead of assuming the audience would know.

Jeff, you are an amazing teacher and have been very instrumental in expanding the Ansible community. Thank you so much for these videos.

[silverywingsagain]

I've been doing devops with ansible since 2018 and I learned a lot of it from roles that you wrote. Thanks for that! Glad I found your channel.

Lots of experience with clustering went into this well thought out video. Thanks. 'Pi Dramble' great for learning clustering and testing. Sandia National Labs uses them as a low cost cluster theory tester.

I'm a little jealous you've got your hands on one of those boards. I pre-ordered one just a week or two ago.

[rodneyflores]

This is everything I've wanted. Bought a ClusterHat a year ago and had no idea what do with it. Informative and encouraging, I don't feel so lost.

That Turing board should be called a Custard board; "A game changing Custard Pi."

[rajat]

i didn't understand anything.


But it was amazing to watch!

[santanudasgupta]

First time hearing you, instant subscribe after hearing your few point of views on systems design and architecture principles!

[Xenthera]

Since my bramble ran droople I called it dramble

Lol sounds like intergalactic cable on rick and morty

[pjotrvrolijk]

Just started playing with my own Pi cluster. I agree that the main thing is to have a testbed in actual hardware. It won't ever be super fast, but it's a great learning experience. Looking forward to your series.

‘What is a cluster?”
Low hanging fruit....

[johnmahugu]

thank you so very much for this, been arguing the concept with my friend for a while now now i have the proof to shut him up and get on with our super computer implementation.

I had been eyeing the Pine64 Clusterboard and Sopine A64 Compute Modules. I hope you mention why you chose the RaspberryPi and compare it to alternative solutions in the next video.

3:25 A touch of brass for that steampunk feel. ;)

I am not a software engineer and dnt no about coding n oll but as a power user, Cluster computing seems very cool, following many cluster projects it seems every project ends up with learning experience only.Really want that it gains some practicality like Powerful password crack-machine, Hosting website, Bulk photo encoder to auto-resize big DSLR images, and many more day to day work even converting(downsizing) collection of 1000s of Video clips and auto uploading to cloud to save a lot of space on cloud.
If some how these above said work are possible on Cluster it will become the best time and pain saver of the world.
Considering a 15 node cluster these tasks are not impossible but the problem is lack of interest of coders and developers in doing so.
I really hope you will develop a cluster which will make life easy&fast.
waiting for your upcoming videos.

Incredibly straightforward and insightful vid. Thank you

[PatrioticGestalt]

Looks like I have to watch this "series". My job wants to look at a Ceph clustering infrastructure. LOL

[CraniumSlows]

Heck ya my dude. Thanks for all your awesome contributions. This was super cool.
