Build connected systems that remain secure, responsive, and reliable—even when the cloud connection fails. Connecting devices is only the beginning. Designing a dependable IoT platform means managing identities, controlling message access, coordinating edge workloads, synchronizing state, and recovering safely when something goes wrong. Architecting the Connected Edge: Next-Gen AWS IoT Core, Greengrass V2, and Zero-Trust Device Messaging by Wells Shepherd guides you through these challenges with practical explanations and code examples. It brings device communication, local processing, cloud integration, and fleet operations together into a coherent architectural approach. Explore how AWS IoT Core and Greengrass V2 support systems that combine cloud capabilities with local autonomy. Learn to define trust boundaries, apply scoped permissions, separate telemetry from commands, and build recovery into your design from the start. Inside, you’ll learn how to: Establish device identities and restrict access to MQTT topics. Design command handling and device state synchronization. Build Greengrass components and configure local messaging. Maintain essential operations during connectivity loss. Route telemetry into AWS services and handle failed events. Monitor fleet health, investigate suspicious activity, and contain compromised devices. Automate staged deployments and evaluate resilience, capacity, and operating costs. An integrated capstone brings these concepts together in a device-to-edge-to-cloud platform, helping you understand how individual services and components work as one system. Along the way, architectural commentary explains the tradeoffs behind buffering, replay, authorization, deployment, and recovery. Whether you’re a cloud engineer, IoT developer, solutions architect, or technical professional expanding into edge computing, this book offers a practical path from isolated experiments to systems designed for real operational demands. Move beyond connecting devices. Learn to architect the connected edge with security, autonomy, and reliability at its core.
