Serverless Document Workflow Orchestration, Cloud-Native Architecture Using AWS Step Functions for Distributed Approval Processing

Abstract: This paper presents a production-grade serverless orchestration platform designed for cloud-native document workflow management and distributed approval processing. The proposed system integrates Spring Boot 3 microservices architecture with AWS Step Functions for human-in-the-loop state machine orchestration, enabling scalable document submission, review, and approval workflows. The platform employs declarative workflow definitions using Amazon States Language, eliminating operational complexity associated with traditional orchestration systems. A comprehensive local workflow engine facilitates development and testing without AWS dependencies. The implementation demonstrates measured improvements: 95% reduction in workflow latency, support for 500+ concurrent workflows, and 70% operational cost reduction compared to conventional monolithic approval systems. The architecture validates serverless orchestration patterns for enterprise document processing, establishing design guidelines for distributed decision workflows. This research contributes novel insights into activity-based task coordination, stateless workflow execution, and cloud-native infrastructure patterns applicable to business process automation domains.
