Most serverless platforms still run your code inside a container, but what if you stripped away the operating system entirely? Lucas and Luna talk to the CTO of a startup that replaced containers with unikernels—single-address-space machine images that boot in milliseconds and cut memory overhead by 80 percent. They walk through the architecture: how the team compiles each function into a lightweight kernel using MirageOS, how they handle networking without a traditional TCP/IP stack, and the surprising debugging challenges when your stack trace ends in the hypervisor. They also get honest about the tradeoffs—no shell access, limited library support, and why this model only makes sense above a certain invocation rate. If you've ever wondered whether serverless can get any leaner, this episode gives you a look under the hood of the next frontier.
