By following the numerous practical examples and crystal-clear explanations, you’ll soon be seeing the benefits of reduced cold start times, improved security and performance, and the freedom of polyglot programming. This book lays out everything you need to take WebAssembly beyond its traditional browser domain. You’ll put on the hats of a systems architect, a backend developer, and even a DevOps engineer to get a full picture of WebAssembly development from both an architecture and development perspective. Inside Server-Side WebAssembly you’ll learn how to: • Develop and deploy server-side Wasm applications • Create and manage Wasm containers with OCI • Compile Wasm components from multiple languages • Scale Wasm applications using Kubernetes • Deploy Wasm applications across different environments • Integrate with databases and machine learning About the technology WebAssembly (Wasm) revolutionized frontend development by enabling secure, high-performance code in the browser. Now it’s doing the same for backend infrastructure as a platform for lightweight, portable applications that run anywhere. In this book, you’ll learn how to build production-grade server-side apps using Wasm. About the book Server-Side WebAssembly teaches you to use WebAssembly components and the WebAssembly System Interface (WASI) to build web back ends. You’ll start with Wasm fundamentals and then quickly start building a realistic content management system complete with data storage, HTTP servers, and AI-generated content. As you go, you’ll see how Wasm integrates code from multiple languages and connects naturally with databases, AI/ML systems, and deployment platforms like Kubernetes. What's inside • Integrate components from multiple languages • Deploy Wasm applications on Kubernetes • Connect Wasm apps to databases and ML systems About the reader For intermediate web developers. Code samples in Rust, JavaScript and Python. About the author Danilo Chiarlone works at Microsoft on cloud and virtualization technologies and is a contributor to several WebAssembly System Interface (WASI) proposals.

Tired of slow cold starts, bulky containers, and persistent security worries in your cloud deployments? Ready to unlock unprecedented speed, security, and efficiency for your microservices? The cloud-native landscape is evolving. While containers revolutionized deployment, they come with inherent overhead and security challenges. Now, a powerful new paradigm is emerging: Server-Side WebAssembly (Wasm) with Rust. This combination offers near-instant startups, ironclad security sandboxing, and unparalleled portability, promising to redefine how we build and run applications in the cloud and at the edge. Server-Side WebAssembly with Rust is your practical, hands-on guide to mastering this transformative stack. Forget theoretical discussions - this book dives deep into the battle-tested patterns, architectures, and operational practices you need to build production-ready, blazing-fast, and fundamentally secure Wasm microservices. Written for experienced Rust developers, cloud engineers, and architects looking to stay ahead of the curve, this book provides a comprehensive roadmap, taking you from foundational concepts to advanced deployment strategies. Inside, you'll discover how to: Eliminate Cold Starts: Understand why Wasm's microsecond boot times are a game-changer for Serverless and Edge computing. Master Sandboxing & Security: Leverage Wasm's capability-based security and Rust's memory safety for truly isolated, secure-by-default services. Architect for Wasm: Design microservice patterns (like Actors and Streams) specifically tailored for the Wasm sandbox, moving beyond traditional container-based thinking. Optimize Your Toolchain: Set up efficient Cargo workspaces, choose the right crates, and build robust CI/CD pipelines for reproducible Wasm artifacts. Achieve Peak Performance: Implement zero-copy data flows, optimize binary protocols (like FlatBuffers), and tune CPU, memory, and I/O for maximum throughput. Deploy Anywhere: Integrate Wasm services into Cloud platforms, Kubernetes, and Edge/CDN environments, choosing the right runtime model (Container, Serverless, or Wasm-Native). Ensure Reliability: Implement comprehensive observability (logs, metrics, traces), conduct chaos testing, define SLOs, and automate incident response with runbooks. Enforce Governance: Utilize Policy as Code (PaC) with Open Policy Agent (OPA) to manage RBAC, compliance, and security rules automatically. Migrate Safely: Follow a step-by-step guide to migrate existing services to Wasm with minimal risk using patterns like the Strangler Fig. Packed with practical examples, clear explanations, and real-world insights, this book doesn't just explain what server-side Wasm is - it shows you how to wield it effectively. Learn to build applications that are not only faster and more secure but also drastically more efficient and cost-effective. Stop fighting container limitations and start building the future of cloud-native applications.

Exploring Blazor
Build and develop web applications with Blazor in C#. This book will cover all three types of Blazor – server-side, client-side, and hosted along with other features of the technology. You’ll see that Blazor is a web UI framework based on C#, Razor, and HTML and how it runs front-end logic using C# either on the server or on the browser using WebAssembly. The author starts by introducing WebAssembly and gives an overview of Blazor along with its various categories. Next, you’ll get started with Blazor where you learn the basics, including Razor syntax implementation. Here you will go over the major differences between Blazor and Razor and how the syntax works. A demo of the layout and navigation for server-side Blazor is followed by usage of Razor syntax to control an application in client-side Blazor. Further, you will go through the project layout, navigation, and routes for the API. Here, you will understand how to access the API from the front end and use the shared library for different models. Moving forward, you will discover how Blazor works with storage, files, and JavaScript. Finally, you will create web applications in Blazor using practical implementations and real-life scenarios for server-side, client-side, and hosted applications. After reading this book you will be able to build web applications with Blazor in C# and .NET Core 3.0. What You Will Learn Bind one-way and two-way data Combine Blazor and JavaScript Understand layout in server-side and client-side applications Execute the general syntax in Razor Who This Book Is For C# and .NET Core developers
