A Deep Dive into Enterprise B2B Integrations: Designing High-Availability File and API Workflows with IBM Datapower and Autosys

Abstract

Enterprise Business-to-Business (B2B) integrations form the backbone of modern digital ecosystems, enabling secure and reliable data exchange across organizational boundaries. As enterprises increasingly adopt hybrid and multi-cloud architectures, traditional point-to-point integrations struggle to meet rising demands for scalability, resilience, and operational continuity. This paper presents a comprehensive exploration of high-availability B2B integration architectures, focusing on the design and implementation of file-based and API-driven workflows using IBM DataPower Gateway in conjunction with enterprise workload automation platforms such as AutoSys.

The article examines architectural patterns that enable fault tolerance, load distribution, and secure message processing across diverse integration channels including SFTP, HTTP/S, RESTful APIs, and event-driven interfaces. It highlights how IBM DataPower functions as a security-first integration gateway for protocol mediation, message transformation, and policy enforcement, while AutoSys orchestrates end-to-end workflow execution, dependency management, and recovery automation. Special emphasis is placed on designing active-active and active-passive deployment models, implementing retry and compensation strategies, and ensuring transactional integrity in large-scale B2B exchanges.

Through reference architectures, workflow diagrams, and comparative analysis, this paper outlines best practices for achieving high availability, observability, and operational resilience in enterprise B2B integrations. The proposed design approach is applicable across regulated and high-volume industries such as banking, insurance, healthcare, and manufacturing, providing a scalable blueprint for modern integration platforms that must operate continuously under stringent service-level agreements.
