Node.js on multi-core machines

Question

Node.js looks interesting, BUT I must miss something - isn\'t Node.js tuned only to run on a single process and thread?

Then how does it scale for m

Answer 1

As mentioned above, Cluster will scale and load-balance your app across all cores.

adding something like

cluster.on('exit', function () {
  cluster.fork();
});

Will restart any failing workers.

These days, a lot of people also prefer PM2, which handles the clustering for you and also provides some cool monitoring features.

Then, add Nginx or HAProxy in front of several machines running with clustering and you have multiple levels of failover and a much higher load capacity.
