Time to explore the next frontier in cloud-native evolution: WebAssembly (WASM). Moving beyond containers and Kubernetes, WASM bears the promise to revolutionize the cloud landscape with unparalleled performance, portability, and security. Can it actually deliver on this promise? We discussed this and more it in this episode.

We delved into how WASM is transforming the way we build and run cloud-native applications, enabling a more efficient, scalable, and flexible infrastructure. We also got latest insights from the Cloud Native Computing Foundation’s work in the domain, the wasmCloud open source project and the tool landscape, along with the work of the WASM working group and standardization efforts with the Bytecode Alliance.

This episode’s guest is Taylor Thomas, Engineering Director working on WebAssembly platforms at Cosmonic. He serves as a co-chair for the CNCF’s WASM working group, and as a CNCF Ambassador. He actively participates in the open source community and is one of the creators of Krustlet and Bindle. His work at Intel, Nike, and Microsoft spanned various containers and Kubernetes platforms as well as WebAssembly platforms.
