We're running on GKE right now, which allows us to iterate quickly, and we'll focus on the unit economics as we scale. As part of our research we've talked to dozens of teams who have already implemented this architecture, and most of them ended up using EKS or GKE (a few did use Firecracker or raw VMs), so they're already subject to those prices and it isn't a problem for them. We know that the unit economics may never make sense for hosting free tools and services, but we're focused on high-value SaaS and internal tools. For our target users, our value proposition is that we replace engineering/devops effort, not just the raw compute we provide.
