A quote from Docker's creator, Solomon Hykes, reveals WebAssembly's potential to replace container technology in cloud environments.
WebAssembly is presented as the next logical step in hardware abstraction, following virtual machines, containers, and serverless functions.
WebAssembly operates using three main parts: a compiler for source code, a compact binary format, and a runtime to execute the code.
Practical examples show how to compile Rust code into Wasm modules for both Node.js and browser environments, followed by an introduction to the WASI standard for secure system access.
WebAssembly provides performance, portability, and security through features like a sandboxed linear memory model and a component model for interoperability between modules.
Cloud platforms like Fermyon and Cloudflare now offer serverless runtimes for deploying efficient and scalable WebAssembly modules.
WebAssembly modules can be run alongside traditional containers in Docker and Kubernetes by using containerd shims and custom runtime classes.
The WebAssembly landscape is shaped by key organizations like the W3C for core specs, the Bytecode Alliance for tooling, and the CNCF for cloud-native projects.
While web applications currently dominate, serverless and cloud use cases for WebAssembly are growing, pointing to its future as a key cloud-native technology.
