Effortless Autoscaling For Java

Autoscale your Java web apps with ease, using request queue time and web utilization.

“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. ”

All about queue time

Most autoscalers rely on generic metrics like CPU or memory, but queue time is the true measure of server capacity. Judoscale was built for queue time from the beginning.

Pre-scale for predictable traffic

Know when traffic spikes are coming? Use Judoscale’s scheduling feature to pre-scale your Java application ahead of time, ensuring you’re ready for peak traffic before it arrives.

The fastest autoscaler

A capacity issue needs to trigger autoscaling as quickly as possible, and Judoscale is the fastest autoscaler available. Our autoscaling algorithm runs every 10 seconds, ensuring your app scales up before users notice an issue.

Reduce your hosting costs

Most Java applications are way overscaled, and Judoscale can help. Our precision autoscaling algorithm lets you scale down without sacrificing performance or peace of mind.

Customize your autoscale behavior

Every Java app is different, and Judoscale gives you complete control. You can scale by multiple instances at a time and tweak the frequency of scaling. Each process is configured independently with a few simple sliders.

As we onboarded larger customers, we expected traffic peaks that needed to be addressed quickly. Judoscale did exactly that.

We had a few times with a spiked increase in load when we exhausted our request queue, resulting in downtime. Judoscale really alleviated that and allowed me to not have to think about it at all. It’s been fantastic so far.

I moved to Judoscale when the business got more serious. I wanted our customers to have quick response times and this was a really efficient way to do that.

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.

We have a wide variance in both server load and response times, which makes trying to scale based on response time completely ineffective. Judoscale just works. We love it!
