WASI-Cloud-Core is a WebAssembly Systems Interface (WASI) proposal aimed to provide a generic way for WASI applications to interact with service including key-value storage, pub/sub, sql databases, etc, regardless of platforms they are running on. In this talk, Attendees will get a dive deep into the proposed interfaces, what capabilities WASI-Cloud-Core offers and why they will make Cloud-Native and serverless application development more portable, secure and simpler.

Attendees will explore the implementation of WASI-Cloud-Core in Spin, a popular framework for building and running microservices with Wasm components. This exploration will include demos of Spin microservice that use state management and event streaming features. This microservice will be deployed to the cloud platform, and then migrated to the Edge environment, without any code change. Attendees will leave with a deeper knowledge of how to build portable, secure and fast WASI applications using WASI-Cloud-Core.
