Cloud Native WebAssembly Applications Are Already Here

And this year also marks WebAssembly’s explosive growth outside of web browsers, especially in server-side and cloud native environments. So far in 2021, the Cloud Native Computing Foundation has officially accepted at least three WebAssembly projects, including WasmEdge Runtime, a cloud native WebAssembly runtime, wasmCloud, a WebAssembly application framework, and Krustlet, a tool to run WebAssembly programs in Kubernetes pods, with many more existing CNCF projects starting to adopt WebAssembly.

Their keynotes discussed the evolution of cloud computing architecture, and provided the context for the rise of WebAssembly as a cloud native runtime.

Since Kubernetes has become the de facto “control plane” for all cloud native applications, WebAssembly must be supported in Kubernetes in order to see serious adoption.

As WebAssembly is incorporated into almost all leading cloud native projects, we could see the pervasive deployment of WebAssembly applications in the cloud in the next 12 months.
