Overview

Cloud-Native High-Performance Systems with Rust and WebAssembly: Build Lightning-Fast Microservices, Deploy Secure WASM Modules, and Master Profiling for Maximum Throughput What if the next big leap in your career wasn't about writing more code-but writing the kind of systems that run faster, scale smarter, and stay secure under real-world pressure? In a world where milliseconds matter and vulnerabilities can cost millions, developers who master performance and safety have the true competitive edge. This book delivers that edge. Cloud-Native High-Performance Systems with Rust and WebAssembly shows you how to combine Rust's memory safety and speed with WebAssembly's portability and sandboxing to build systems that thrive in modern cloud and edge environments. From constructing high-throughput microservices to deploying lightweight WASM modules across Kubernetes and serverless platforms, you'll learn how to design applications that are not only fast but resilient, secure, and future-proof. Inside, you'll discover how to: Build microservices with Actix-Web and async/await that scale gracefully under heavy load. Compile Rust to WASI-compatible WASM modules and run them securely in cloud and edge platforms. Apply profiling and benchmarking techniques using Criterion, Flamegraph, and Tokio Console to eliminate bottlenecks. Use concurrency patterns like worker pools, fan-out/fan-in, and rate limiting to handle massive workloads. Harden deployments with capability-based permissions, sandboxing policies, and supply chain security practices. Deploy confidently with Docker, Kubernetes, CI/CD pipelines, and observability tools like Prometheus, Grafana, and OpenTelemetry. What makes this book stand out is its relentless focus on the practical. Every concept is paired with implementable strategies, proven tools, and production-ready patterns. Whether you're optimizing APIs to handle a million requests per second or experimenting with WASM at the edge, you'll gain skills you can apply immediately. If you're ready to stop settling for ""good enough"" and start building lightning-fast, secure, and reliable cloud-native systems, this book is for you. Take control of performance. Build systems you can trust. Grab your copy today and become the developer who engineers the future.
