Active–active cloud-native architectures are widely adopted in mission-critical domains such as railway operations, healthcare platforms, and large-scale enterprise systems to achieve near-zero downtime, high availability, and fault tolerance. Distributed caching and real-time synchronization are foundational enablers of these architectures, ensuring low-latency data access and consistency across geographically distributed deployments. However, the combination of active–active execution, event-driven microservices, and distributed state introduces substantial challenges related to consistency, observability, and operational complexity. This paper presents a comprehensive architectural and empirical study of distributed caching and real-time synchronization in active–active cloud-native systems. We propose a reference architecture integrating event-driven communication, distributed in-memory data grids, and AI-driven observability. Experimental results demonstrate significant improvements in latency, availability, and mean time to recovery, providing practical guidance for designing resilient mission-critical platforms.
