Fast, Scalable, Secure: WebAssembly and the Future of Isolation

We have reached the limits of traditional hardware based isolation technologies such as  virtual machines, containers, and processes. As a result, developers are increasingly turning to light weight isolation technologies, such as WebAssembly , that can offer startup times, IPC overheads, and resource footprints 10x-1000x lower than traditional hardware based isolation.  This is changing the way we think about serverless edge computing today, and will impact many other areas of the tech stack in the coming years.

In this talk we will explore the isolation technologies that underlie WebAssembly, and the limitations of the current state-of-the-art. I will talk about our work to overcome these limitations on current hardware, and to bring ultralight isolation that is fast, scalable and secure to next generation processors.

Automating Bare Metal to Improve Your Quality of Life

Wednesday Oct 4 / 02:45PM PDT

Everything we build is built upon a substrate. Even the cloud computing we directly, or indirectly, use every day is built upon a substrate. In computing, we often call this substrate Bare Metal, and the closer you get to it, the more potential you can unlock... if you're willing.
