Open Source Summit + Automotive Linux Summit Japan 2019

In this talk, we will highlight an alternative way of doing serverless which doesn't depend on using Linux containers or docker. We talk of a very novel way on how functions can be created with minimal bootup time and consuming minimal resources and still having proper isolation in the context of multi-tenanted functions.
We look at the evolution of web assembly (WASM) and Web assembly system interface (WASI) as one of the ways in which functions can be built in languages like C, Nodejs, Rust and compiled to a WASM format and executed within a wasm runtime. The talk also compares the benefits of the approach over the approach of using containers and how this can change the game in the near future.
We will also highlight how multi-tenanted functions are run and how isolation of memory, CPU can be achieved. We also touch upon security aspects like using capability-based security can be achieved.
