The rise of WebAssembly (WASM) has sparked comparisons with Docker which often leads to questions and confusion: Are WASM and Docker competing technologies?

In this talk, we will see how this is far from the truth. On one side, Docker revolutionised how we bundle and deploy applications, offering unparalleled portability and simplifying workflows across environments. On the other hand, WASM brings speed, security, and efficiency, enabling the execution of code written in languages like C, C++, and Rust almost at native speed, performance, and rapid startup time even in the browser.

We will explore how these two technologies bring the best of both worlds and help developers achieve portability, efficiency, security, and flexibility. We will also look at how Docker is actively working to make WASM mainstream by allowing WASM container images to be hosted on DockerHub and run WASM containers alongside traditional Linux and Windows containers.
