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 workers, and we scale them 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 that we’ve written about extensively, 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.

We have very large fluctuations in the load of our application, and we wanted to save money. Judoscales proved itself well, it reacts fast to the traffic spikes and Heroku dynos spin up quickly.

Judoscale has been a huge strategic win for us. We’re spending less money to deliver a better experience to our users. The cost savings listed in the app dashboard is extremely conservative as the service lets us avoid tremendous backend costs on Heroku.
