Look ma, no OS! Unikernels and their applications
summary
Claim: Unikernels shrink runtime to kilobytes or megabytes (a static site in about 4 MB vs ~1 GB on Linux), remove whole OS layers, and cut the attack surface so density and performance rise while debugging scope falls. Demos and tooling are concrete: Jitsu just-in-time summoning deploys unikernels on DNS, a rump run WordPress stack actually boots as separate unikernels, and projects shown include Mirage OS and OSv plus KVM/Xen/Arm support and a Vagrant repo to reproduce the builds.
