Rather than run an application all the time, what if we could only start it when it was needed, and thus avoid the cloud cost of running unused services? This was the idea behind scale-to-zero. WebAssembly has an answer.

For any ecosystem to grow, it's important for standards to be implemented that establish trust with users within the community. This is the motivation behind the Bytecode Alliance, a non-profit standards setting organization devoted to building secure-by-default software.

Spin is our new, open source WebAssembly framework - for building, distributing, and running WebAssembly apps.

Serverless did not quite live up to its promise. But why? Partly, it was never well-defined. Also, the vision overreached the technology available at the time. But things are different now. Has serverless failed or is it about to hit a renaissance?

Python can now be compiled to Wasm. In this post, we show how to run cloud-side Python in a WebAssembly runtime.

WebAssembly may have started as a browser technology, but it has moved outward. One hugely promising space for WebAssembly is in the cloud. Its security, speed, size, and flexibility make it a great basis for building cloud services.

Introducing a new community for sharing WebAssembly news and information

The recent Log4j attack provides an opportunity to talk about that characteristic and see why WebAssembly is resistant to this kind of attack.

The promise of WebAssembly is that it can be a common runtime for all sorts of languages. But there are differences between how we traditionally write in scripting languages (JavaScript, Python, Ruby) versus compiled languages (C/C++, Go, Rust). In this post, we survey the WebAssembly landscape to see what is happening along these fronts.

It is common to hear WebAssembly compared to Docker Containers (or OCI Containers). What's the difference? We look at the key differences between Wasm and Docker Containers.

Microservices are serving us well in many ways. But in some ways, we can do better. Will microservices v2 be powered by WebAssembly?

What is WebAssembly? Is it the JavaScript killer or a performance tool for the browser? Is it a replacement for Docker? Or a clone of Java? Or is it a better eBPF? Lots of ideas are swirling. So let's get to the heart of the matter.

LibreOffice in WebAssembly (LOWA) is a promising project. But more exciting is what this new project demonstrates about the WebAssembly ecosystem.
