Cloud Native Wasm Day EU, Paris

Cloud Native Wasm Day (co-located with KubeCon + CloudNativeCon EU, 2024) is always a great event but this year was a little different. In 2024, discussions are turning from theory towards working with Wasm in practice, with companies in a variety of sectors sharing their experiences.

What's particularly exciting for us, as CNCF wasmCloud maintainers, is how quickly wasmCloud is being adopted. So many of this year's talks come from companies already working with wasmCloud; many in production. We've summarized all the talks from this year's event and recommend paying particular attention to presentations from wasmCloud community users Orange and Machine Metrics.

Extending Security with wasmCloud 1.0 and Open Policy Agent

From the beginning, wasmCloud has used zero-trust architectural patterns and Wasm's intrinsic isolation to deliver secure-by-default distributed computing. Our security posture was validated in an October 2023 audit from OSTIF and Trail of Bits, where we received excellent marks. It's important, however, that our approach to security is not only robust and default, but extensible.

With wasmCloud 1.0, our flexible, pluggable policy service API integrates easily with standard cloud native tooling like Open Policy Agent. As you take wasmCloud to production, operators can use the tools they're already using to extend and tailor the platform's already-deep security.

Vendor-neutral apps with wasmCloud and WASI 0.2

WebAssembly is bringing us closer than ever to a world of "write once, run anywhere." From developer platforms to the browser to embedded devices, Wasm gives us a way to write portable, efficient, sandboxed code. The WebAssembly System Interface (WASI) and the Component Model extend the power of WebAssembly with standard APIs for core functionalities like HTTP, CLI, I/O, and more—as well as a specification for compiling Wasm applications as interoperable, composable components.

Now, wasmCloud 1.0 brings the Component Model and the standard APIs of WASI 0.2 to production-grade distributed computing. By embracing community standards, wasmCloud ensures that your business logic is truly vendor-neutral. Components built for wasmCloud 1.0 run anywhere that supports WASI 0.2, and any component you've built to target WASI 0.2 is ready to run distributedly with wasmCloud.

We’re excited to see our friends again as we embark on a whistle-stop tour of two of our favorite European events (and cities) in the 2024 conference calendar: WASM I/O, Barcelona and KubeCon + CloudNativeCon Europe 2024, Paris. With the release of WASI 0.2 and the WebAssembly component model, we’re taking wasmCloud 1.0 on tour—introducing it to cloud native developers, and platform engineers, as the best place to bring components to life in production environments.

Components written in Python on wasmCloud

WASI 0.2.0 is in the wild, pushing forward common standards for portable, language-agnostic components and interfaces. That means it just got a whole lot easier to create WebAssembly components from any language—and have them work together with other components of any provenance. Better still, it's now possible to "bring your own Wasm components" from any language that compiles to WASI 0.2.0 and run them as distributed apps in wasmCloud.

stable foundation and community

WASI Preview 2 officially launched! After a vote in the WASI Subgroup of the W3C WebAssembly Community Group, the standard set of interfaces included in the launch of Preview 2, aka WASI 0.2.0, is ready for use by library implementers. We've been closely tracking the different release candidates of WASI 0.2.0 over the last 6 months, and wasmCloud will update its runtime WIT definitions to the pinned versions in just a few days.
