Bringing any new tool into an organization can feel like an uphill battle. It’s difficult to overcome inertia, even with the promise of improved workflows and happier teammates. Any change is hard, harder still when colleagues have grown attached to “the way we’ve always done things.” How can you get your team to see the light when you know there’s a better way?

Starting today, customers using CircleCI behind their firewall can now access all of the features and performance that CircleCI 2.0 delivers, including Workflows, full Docker support, and VM-based jobs. CircleCI 2.0 has been generally available for our cloud customers since early July, and the results for those who have switched to 2.0 have been impressive.

Background

Amazon’s Auto Scaling groups (ASG) are, in theory, a great way to scale. The idea is that you give them a desired capacity, and the knowledge of how to launch more machines, and they will fully automate spinning your fleet up and down as the desired capacity changes. Unfortunately, in practice, there are a couple key reasons that we can’t use them to manange our CircleCI.com fleet, one of the most important being that the default ASG termination policy kills instances too quickly. Since our instances are running builds for our customers, we can’t simply kill them instantly. We must wait for all builds to finish before we can terminate an instance.

Today, we are excited to announce not one, but two new offerings!

After acquiring Distiller to help realize our mobile vision, and more than a year in public beta and limited release, CircleCI for OS X is generally available today.
