Autoscale Your Rack App The Right Way
$ bundle add judoscale-rack
Why autoscale your Rack app?
Most Rack apps are over-provisioned. You’re paying through the nose for resources you don’t need, but you do it because you’ve been burned with downtime.
Even worse, you still encounter downtime and slow-downs! Traffic is variable and sometimes unpredictable, so even your extra servers aren’t always enough.
Autoscaling is the solution here, and it’s pretty simple. We monitor the capacity of your Rack app, and we scale your servers accordingly. You’ll never pay for resources you don’t need, and you’ll always have capacity to meet those sudden bursts of traffic.

What makes Judoscale different?
While most autoscalers rely on generic metrics like CPU or total response time, Judoscale monitors the request queue time in your Rack app. Queue time is a way more reliable capacity metric that we’ve written about extensively, and we built our autoscaler with queue time in mind from the beginning.
We also give you a whole lot of control and visibility into your autoscaling that you won’t find elsewhere. Autoscaling is all we do, and we’ve been doing it for a long time.

Explore the configs in our sandbox app →Judoscale’s deep integration with Sidekiq queues let us easily tag which queues we wanted a faster response. We were able to tune our scaling sensitivity for exactly our usage pattern of intermittent batches of large jobs.

If I was the king of the world, I would make it illegal to horizontally scale based on execution time. Scale based on queue depths, people!

I found Judoscale through Nate Berkopec’s Rails Performance workshop. Glad I did, because we’re very happy with Judoscale!

You guys are rock stars!! I think this is the 3rd time now that you've already had a solution ready to go to solve our problem. This is exactly what I was looking for!!

Chameleon has been extremely stable thanks to Judoscale. We have very high spikes in traffic, and I don’t even have to think about it.

We could see the care in Judoscale’s documentation, the gems were well-documented and designed with a general sense of quality.

We’re really impressed by the simplicity and ease of use of Judoscale. We’ve gone from constant worries over site performance, to complete confidence in our configuration. What a great tool!
