Wasm, WASI, Wagi: What are they?

Wasm, WASI, Wagi: What are they?

Any new technology comes with a litany of new terminology. WebAssembly is no different. In this post, we take a look at how Wasm (short for WebAssembly), WASI (the WebAssembly System Interface) and Wagi (WebAssembly Gateway Interface) work together. The Fermyon Spin framework makes use of all three of these.

WebAssembly Languages

WebAssembly Languages

With WebAssembly gaining momentum, a new breed of WebAssembly-specific languages have arrived on the scene. In this post we cover a few of these, including Grain and AssemblyScript

What is Bindle

What is Bindle

Bindle is the silverware drawer for Wasm objects. It provides an efficient and flexible packaging system for component-based applications that have variable dependencies.

The Scale to Zero Problem

The Scale to Zero Problem

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.

Why the Bytecode Alliance is important to the Wasm ecosystem

Why the Bytecode Alliance is important to the Wasm ecosystem

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.

Introducing Spin

Introducing Spin

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

A Reckoning for Serverless

A Reckoning for Serverless

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?

Introduction to WebAssembly on the Cloud

Introduction to WebAssembly on the Cloud

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.

Scripting Languages and Compiled Languages in WebAssembly

Scripting Languages and Compiled Languages in WebAssembly

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.

Rethinking Microservices

Rethinking Microservices

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