Clustering ruby applications

[Pradeep bhatt]

Is it possible to cluster Ruby applications ? Who provides the clustering support ?

[Lasse Koskela]

What do you mean by "clustering a Ruby application"? And are you perhaps referring to Rails applications rather than Ruby applications?

Yes I meant Rails application. Can I have a cluster defined for Rails application for scalability and reliability purpose.

Rails apps can be clustered by, for example, having a web server load balance traffic to a Mongrel cluster and using memcached to keep sessions in sync between the Mongrel servers.

Here's a nice little article with pretty pictures of a couple of alternative clustering setups.
