Abstract

Real-time enterprise applications rely on distributed event flows that must survive service failures, traffic spikes, and uneven recovery conditions. This article examines how architects can build fault-tolerant event processing systems without treating resilience as a single broker feature. The aim is to identify design principles that preserve delivery continuity, state consistency, and operational stability in enterprise platforms. The review draws on ten recent academic sources on stream processing, transactional guarantees, message brokers, observability, complex event processing, and runtime control. The analytical section links broker choice, partitioning, checkpointing, replay, and telemetry with recovery quality under load. The article argues that resilient behavior emerges when teams coordinate the messaging layer, the stateful processing layer, and the operational control layer from the start. The proposed interpretation offers a practical decision model for enterprise platforms and educational systems that must keep processing requests during synchronized surges in user activity and failures across shared infrastructure.
