The cloud is a major success story in the tech industry: easy to get started with, seamless scalability and loads of services at a click of a button. What has become more evident in the past few years is that while it's convenient, it can be quite inefficient: heavy VMs, long running VMs, bloated software stacks and long-running idling services are commonplace; the end result are expensive infrastructure bills. In this talk we will give an introduction to Unikraft, a Linux Foundation open source project that aims to change this by allowing users to (1) automatically build specialized virtual machines (aka unikernels) for standard, off-the-shelf applications and even closed code, (2) painlessly deploy these on cloud infrastructure (e.g., Amazon EC2 and GCP), and (3) seamlessly integrate with major existing frameworks such as Kubernetes and Prometheus. Our evaluation using applications such as nginx, SQLite, and Redis shows that running them on Unikraft results in a 1.7x-2.7x performance improvement compared to Linux guests, and a test of nginx on Amazon EC2 shows 50% savings on our cloud infrastructure bill. Finally, we will cover how to support a wide variety of programs while not being fully POSIX compatible, and will show a few short demos of Unikraft in action.
