Great video. Straight to the point. I got clustering on my app running in 15 minutes thanks to you.

[danielyaa]

dawg, whats up with you loop increment

[darkthrongrising]

So yeah, I like the Cluster module now.

I realize I'm really late on this, but could you elaborate on the point you made about NewRelic being loaded in the cluster file and not in server? If my understanding of cluster.fork is correct this shouldn't matter. The whole node process is recreated so module caching isn't really possible between each child process. I think you'll inevitably get 8 (assuming the 8 core machine you mentioned in the video) instances of the NewRelic client no matter where you place that import. Am I missing something?

Hi,
You should do a tutorial on how you setup an app using cluster and socket.io.

This is great video you made things easy thanks for sharing information

[shreyasbhargava]

short and easy to understand great vedio

What happens if we conditionally do not call app.listen inside the else block? Does the process die or it still exists?

[gtasapcuser]

When you use node clustering how to ensure that a if the request cycle remains with one that started the request because if we are using app.locals to store variables to render on client side it will be different for each different clustered worker process

Great video... question, what's your sublime theme and color scheme?

[jamesbedont]

Lets say I have 3 docker containers on a 4 core server; each container running a cluster'd nodejs app. How many worker processes would there be? Seeing as my current understanding is there can only be one worker per core of the machine I am a bit confused on this point.

The cluster module isn't stable yet. I think it would be better to manually set up Haproxy or nginx. What do you think?

[alkolaqi]

great video... You are impressing me so much because you go to the point....
Can you do tutorials begin to end Node.js or send me a place where I can start.. 
Love ur channel... keeping doing the great work 

[ravitejavankam]

How different is it from pm2 clustered instances?

[HermanWillems]

I want to build a redundant setup for NodeJS. If i have 2 raspberry pi's with NodeJS cluster. Will this automatically make the setup redundant? And does it work without a load balancer? (im more for automation purposes so redundancy is important for me)

[ashitagupta]

Hello,
can you please explain us how node js is behaving /working if more than million request came at a same time.

[MilanVVVVV]

tHaTs a GreAT FEaTuRe, no, that's a consequence of its architecture.

[jackmoscovi]

How do i email you? i need some advice.

[kaanozcan]

I was thinking to do it with nginx. Which one do you think is better? Are they the same thing?

[troooooper]

i need your brain..to copy paste...can i get it?
