WASI and the Cloud - Jiaxiao Zhou, Microsoft & Dan Gohman, Fastly

WASI Preview2 is the next major version of WASI, the WebAssembly System Interface. Dan will cover WASI's evolution from Preview1 to Preview2, coming features such as WASI sockets, with demos along the way illustrating how all of these technologies fit together. This talk then will explain why WASI is not merely POSIX APIs, which leads into a discussion of WASI-Cloud, a family of interface proposals for common applications APIs, such as key-value stores, pub/sub, and SQL databases. It intends to make cloud-native and serverless application development simpler and more portable. It will show off some demos of microservices capable of doing service invocations, event streaming and state managements. Finally, this talk will conclude with a glimpse into the future of WASI. Attendees will leave with a comprehensive understanding of WASI and its place in the distributed application landscape.
