How to Extend WebAssembly with Host Functions

By DarumaDocker，WasmEdge Contributor in charge of the development of WasmEdge-bindgen WebAssembly was developed for the browser. It gradually gain popularity on the server-side, but a significant disadvantage is its incomplete functionality and capability. The WASI proposal was initiated to solve these problems. But the forming and implementation of a standard is usually slow. What if you want to use a function urgently? The answer is to use the Host Function to customize your WebAssembly Runtime.…

Women in Open Source: Take a Female Perspective

Today is March 8th, International Women's Day, a festival to celebrate women's important contributions and great achievements in different fields of society. With a growing number of females taking interest and getting good at coding, women are playing an increasingly important role in the IT industry. Today, let's take a closer look at the stories of the female developers who contributed to or are developing the WasmEdge project, so as to see the perspectives of women in open source.…

Use Kubernetes and kind to Manage WebAssembly Apps

This article is based on Sven Pfennig’s presentation at the WasmEdge Community Meeting in Jan 2022. Pfennig discussed why and how to run WebAssembly apps in a Kubernetes cluster. Using kind and WasmEdge, he showcased a simple solution. Please watch the original video here: https://www.youtube.com/watch?v=-oumohWVgSI&t=493s Background kind is Kubernetes In Docker, that is, to deploy all the components required by Kubernetes in a docker container. kind is a simple and easy-to-use version of Kubernetes, often used in local testing use cases.…

eBPF and WebAssembly: whose VM reigns supreme?

The two hottest lightweight code execution sandboxes / VMs in the cloud-native world today are eBPF and WebAssembly. They both run high-performance bytecode programs compiled from C, C++, and Rust. The biggest difference, however, is that eBPF runs inside the Linux kernel while WebAssembly runs in the user space. eBPF has some programming restrictions that makes it safe for kernel use cases (eg no infinite loops). But that also means that eBPF is Turing incomplete.…

Containerization on the edge

This work is supported by Second State and FutureWei based on Open Source projects WasmEdge and seL4. Application containers, such as Docker, are a key driving force behind the growth of Cloud Native applications. However, while the Cloud-Native development paradigm has proven very popular, it is difficult to expand the Cloud-Native infrastructure beyond large data centers since application containers require significant amounts of computing resources. For example, Docker does not support real-time operating systems (RTOS) and only works on POSIX systems.…

Multiple Remotely Based Job Openings

Second State‘s open source WebAssembly runtime WasmEdge has been hosted as a sandbox project by CNCF under the Linux Foundation, the only Wasm runtime at CNCF. Its use cases include serverless apps, embedded functions, microservices, smart contracts, and IoT devices. Two decades ago, we witnessed the migration of Java from the browser to the server side. A decade ago, we saw the migration of JavaScript from the browser to the server.…
