In this talk, we will explore how WebAssembly (Wasm) is poised to become a major player in the future of cloud computing. Wasm is a binary format that can be compiled from many different languages and run on a variety of operating systems and architectures. Its near-native performance, portability, and security make it an ideal solution for addressing the challenges of distributed application development, deployment, and maintenance.

One of the fastest-growing Cloud Native trends is the adoption of Wasm, with projects such as Docker+Wasm (now in Beta) launched with a partnership between Docker and the CNCF’s Wasm runtime WasmEdge. Wasm's efficiency and speed make it ideal for on-demand scaling, while its sandboxed environment and deny-by-default approach to granting access to capabilities provide enhanced safety and security.

In this talk, we will delve into the key value propositions offered by Wasm and how it can help address the challenges posed by CPU diversity, multiple operating environments, security concerns, distributed application architecture, and scalability.

The talk will start with an introduction to WebAssembly and its relevance to cloud computing. I will discuss the growing adoption of Wasm in the cloud native community and the partnership between Docker and the CNCF’s Wasm runtime WasmEdge. I will delve into the key benefits offered by Wasm and provide examples of how it is being used in the cloud native space. Finally, I will summarize the main points of the talk and provide some final thoughts on the future of Wasm in cloud computing.
