Load balancing with Ruby on Rails

[MartinIAm]

I want to scale my Ruby on Rails projects and use a load balancer in front of it but I’m not really sure how to do this. How will I configure storage for this and scaling across multiple virtual machines? I use puma right now because it is multithreaded and can be used in a cluster, but I’m not sure how to setup the cluster.

i had done this for my cloud. The trick is to sprung up more processes, use a message queues, use cache, shard your databases, then rinse and repeat across as many server machines as you need to. To make this process less tedious, consider using docker, kubernetes, and automation tools like ansible.

I don’t run it off the cloud as I am self hosted so kubernetes and ansible isn’t a viable option for me but docker does sound like an option. 

 

You also didn’t explain how you manage your storage across the multiples virtual machines.

For storage, i used mongodb and shard them as i said earlier. It is the industry practice for scaling out.

I didn't know you could use mongodb for storage.

Oh! I think I understand now. So I can use mongodb as storage for active storage, and the use something like NFS to have the same replicated project across the multiple servers.

I used gridfs on Mongo. Idk if this is the ideal way to store large files but hey, it works well enough for me.

Just to confirm, do you use Mongo in config/storage.yml?
