He then walks you through code examples using Rust, Golang, and JavaScript to demonstrate how they can be compiled to Wasm and consumed from Wasm runtimes deployed standalone, as well as on the cloud. You will see how a wasm module can be run through an http interface, and how Wasm fits into CNCF projects such as Kubernetes and Istio service mesh. After that, you'll learn how the polyglot nature of WebAssembly can be leveraged through examples written in languages like Rust and consumed via Golang and JavaScript, with a focus on how WebAssembly allows interoperability between them. You'll gain an understanding of how Wasm-based modules can be deployed inside Linux containers and orchestrated via Kubernetes, and how Wasm can be used within the Istio proxy to apply rules and filters.\u003cp\u003e\u003c\/p\u003e \u003cp\u003eAfter reading this book, you'll have the knowledge necessary to apply WebAssembly to create multi tenanted workloads which can be polyglot in nature and can be deployed on cloud environments like Kubernetes.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eWhat You Will Learn\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUnderstand how Wasm can be used for server-side applications\u003c\/li\u003e\n\u003cli\u003eLearn about Wasm memory model and Wasm module layout\u003c\/li\u003e\n\u003cli\u003eHow communication between host and Wasm module is facilitated\u003c\/li\u003e\n\u003cli\u003eThe basics of Wasm sandboxing and security\u003c\/li\u003e\n\u003cli\u003eThe fundamentals of tooling around Wasm, such as WAT and Wasm-pack\u003c\/li\u003e\n\u003cli\u003eCreate a Wasm module in Rust and consume it from JavaScript, Rust and Golang.\u003c\/li\u003e\n\u003cli\u003eGrasp how Kubernetes can be used to orchestrate Wasm-based workloads\u003c\/li\u003e\n\u003cli\u003eHow Wasm fits into service mesh\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e \u003cp\u003e\u003cb\u003eWho Is This Book For\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eSoftware developers\/architects who are looking to hone their skills in virtualization and explore alternatives to Docker and container-based technologies for their workload deployments.
