Autoscale Your Celery Workers The Right Way

Avoid downtime. Reduce hosting costs. Use queue latency to monitor your workers and scale automatically.
$ pip install 'judoscale[celery-redis]'
You'll be autoscaling in minutes

Why autoscale your Celery workers?

Most Celery setups 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 unexpected queue backlogs! Workloads are variable and sometimes unpredictable, so even your extra workers aren’t always enough.

Autoscaling is the solution here, and it’s pretty simple. We monitor the capacity of your Celery queues, and we scale your workers accordingly. You’ll never pay for resources you don’t need, and you’ll always have capacity to meet those sudden bursts of tasks.

What makes Judoscale different?

While most autoscalers rely on generic metrics like CPU, Judoscale monitors the queue latency in your Celery setup. Queue latency is a way more reliable capacity metric for workers, and we built our autoscaler with queue latency 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.

Most applications have greatly overprovisioned resources, because resources are provisioned manually in response to developer stress (pages, calls, incidents) rather than automatically (in response to metrics, e.g. request queue time).

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.

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.
