Transforming Enterprise Operations At National Scale: Engineering Real-Time Distributed Event Systems For 100,000+ Frontline Workers

Abstract

Contemporary business organizations are confronted with the severe issues of providing real-time operational information to mobile workforces that are located across geographical boundaries and functioning under extreme resource limitation conditions. Early broadcast-based designs are ineffective at scale, causing disastrous battery usage and network bandwidth waste when supporting tens of thousands of simultaneous mobile connections. This article introduces a full event-based architecture that fundamentally reinvents the operation data flow of an operational distributed system to mobile devices. The proposed subscription-based event filtering pattern enables mobile clients to explicitly express their interest in a given event stream, resulting in server-side event filtering that significantly reduces the transmission of irrelevant data. The architecture includes three special communication channels designed for specific operational needs, a flexible connection management system that changes based on the application's status, and a detailed monitoring system that helps improve performance before issues arise. Optimization methods for the battery use a mix of adjusting how communication works and improving how the client processes data and compresses information. The methodology of implementation focuses on rolling out and intensive monitoring, gradual geographical broadening, and refining through telemetry. The framework reveals the wide applicability to sectors that need high-frequency event streams for resource-constrained mobile gadgets.
