Achieving High Availability for AWS IoT Greengrass with Pacemaker: A Guide to Resilient Edge Computing

In industrial IoT environments, edge computing downtime can be costly and disruptive, making high availability essential. This article walks through how to use Pacemaker, a powerful cluster resource manager, to implement robust high availability patterns for AWS IoT Greengrass, ensuring continuous operations even during hardware failures or network disruptions.

The guide covers two key high availability patterns: Active/Passive for maximizing data consistency and Active/Active for optimizing throughput and scalability. Learn how to integrate Pacemaker with Greengrass to achieve automated failover, state replication, and seamless service continuity. It includes a step-by-step implementation of these patterns, with detailed setup instructions and testing procedures, to build enterprise-ready edge infrastructures. Whether you’re managing critical industrial systems or running real-time analytics at the edge, this solution ensures your edge workloads remain resilient, scalable, and always on.
