IBM App Connect Enterprise

IBM App Connect Enterprise (ACE), formerly known as IBM Integration Bus (IIB), is a comprehensive integration platform designed to help organisations seamlessly connect applications, APIs, systems, and data across hybrid and multi-cloud environments. ACE acts as the connective tissue of modern digital architecture, enabling enterprises to unify disparate systems and streamline the flow of information across their business.

In a world where organisations operate with an ever-growing mix of legacy systems, SaaS applications, cloud platforms, and microservices, ACE provides a reliable and scalable foundation for integration. It offers a single, consistent platform for building, running, and managing integrations, ensuring that critical data moves smoothly and securely where it needs to go — no matter the format, protocol, or underlying technology.

ACE empowers development teams with a powerful, graphical integration designer that dramatically accelerates delivery. Developers can visually model message flows, map data between formats, and orchestrate complex interactions without relying on extensive custom code. This visual tooling reduces development time, minimizes human error, and helps organisations standardize integration patterns across teams and business units. Reusable assets, templates, and connectors further speed up delivery while improving consistency across integration projects.

With its broad library of built-in connectors and transformation capabilities, ACE supports integration across virtually any system — from mainframe and on-premises applications to modern cloud services and event-driven platforms. It manages everything from simple data mapping to complex routing, API mediation, and event orchestration. ACE also supports a wide variety of protocols and message formats, allowing organisations to bridge technologies that span generations of IT evolution.

Performance and reliability are at the core of ACE’s architecture. Its lightweight, high-performance runtime can be deployed on-premises, in containers, on cloud platforms like IBM Cloud or AWS, or as part of Red Hat OpenShift. This flexibility enables organisations to modernize at their own pace while maintaining operational continuity. As workloads scale, ACE provides enterprise-grade resiliency, throughput, and governance to support mission-critical integration scenarios.

Security and compliance are built into every layer of the platform. ACE handles sensitive data with robust encryption, secure connectivity, role-based access controls, and comprehensive auditing. It ensures organisations maintain visibility and control over how information flows across systems, even in complex distributed environments.

As businesses accelerate their digital transformation, ACE plays a vital role in enabling agility and innovation. It allows organisations to expose legacy capabilities as APIs, integrate cloud-native services with core systems, and orchestrate data flows that power analytics, automation, and real-time decision-making. Whether connecting internal systems or enabling partner ecosystems, ACE helps organisations break down silos and create seamless digital experiences.

With its powerful toolset, extensive integration capabilities, and proven enterprise reliability, IBM App Connect Enterprise remains one of the most trusted integration platforms in the industry. It provides the flexibility, speed, and governance needed to keep systems connected, data flowing, and businesses moving forward in a rapidly evolving digital landscape
