About the Book
If you're a Rust developer ready to deploy rock-solid systems across cloud, serverless, and the network edge, harnessing zero-cost abstractions to deliver maximum security, scale, and speed, this book is your hands-on gateway. You'll move beyond "hello world" examples into full production patterns: multi-tenant isolation, operator-driven Kubernetes, encrypted service meshes, serverless pipelines, and sub-50 ms edge functions all written in safe, memory-leak-proof Rust.
Inside, You'll Build and Master:
- A multi-tenant host that enforces memory safety by design, combining Rust's ownership model with WebAssembly sandboxes (Wasmtime & WASI) to isolate untrusted workloads.
- Kubernetes operators and CRDs with kube-rs, generating type-safe API bindings and a reconciler loop that self-heals your custom resources.
- mTLS service endpoints using rustls and runtime secret rotation via Obelisk, so certificates never rest unencrypted on disk or linger in memory.
- A Rust-powered service mesh sidecar (Linkerd2-proxy) with Tower middleware for automatic mTLS, retries, and per-service telemetry.
- An architecture comparison of microservices vs. modular monoliths in Rust, learn when in-process calls win and how to extract independent services without rewriting business logic.
- High-throughput async worker pools consuming Kafka or NATS streams, complete with at-least-once delivery, partition balancing, and backpressure.
- Actor-model fault-isolation patterns (Actix and Riker) that let supervisors restart crashed components without cascading failures.
- Circuit breakers, exponential-backoff with jitter, and graceful degradation strategies to keep user flows alive when dependencies misbehave.
- Seamless FaaS functions on AWS Lambda and OpenFaaS, optimized for cold-start speed with LTO, strip, and UPX compression.
- Edge-deployed Rust Wasm modules on Cloudflare Workers and Fastly Compute@Edge, delivering sub-millisecond TLS-terminated HTTP handlers at every POP.
- Real-time ML inference pipelines in Rust using TensorFlow-rust or pure-Rust ONNX (tract), batching sensor data through spawn_blocking pools for GPU/CPU acceleration.
- Offline-first mobile and browser-based patterns with sled or SQLite, journaling user actions locally and progressively synchronizing via CRDTs or LWW conflict resolution.
- End-to-end observability: OpenTelemetry spans, Jaeger tracing, Prometheus counters and histograms, Grafana dashboards, and structured logs with tracing/log4rs.
- Chaos engineering experiments, failpoints, Kubernetes NetworkChaos, and PodChaos to validate resilience under latency spikes, resource exhaustion, and process crashes.
- Full source walkthroughs: a cloud-native ToDo API service, a serverless image resizing pipeline, and an edge-deployed chat bot, complete with CI/CD, Helm charts, and GitOps patterns.
