Open Source Summit Japan 2023

The microservices architecture has become the go-to approach for modern internet businesses, with systems composed of numerous containers powering each service. As container usage surges, so does the need for efficient, lightweight, and secure alternatives. WebAssembly (Wasm) has emerged as a complementary technology to Linux containers, offering a more lightweight, secure, and high-performance solution for containerized applications. In this talk, we will explore the benefits and use cases of hybrid container architectures, which combine Wasm and Linux containers in a single microservices system. We will discuss the challenges faced by current microservices and compare the features of Wasm containers and Linux containers. We will also demonstrate how popular container tools support Wasm containers and how Kubernetes can be used to manage both Wasm and Linux containers in production environments. This talk will provide practical insights into the adoption of cloud-native Wasm in your applications, showcase developer tools and partnerships that enable fully-fledged microservices in WebAssembly, and offer a lightweight and secure alternative to traditional container-based applications. Attendees will learn how to leverage the benefits of hybrid container architectures and optimize their microservices systems using Wasm and Linux containers.
