Compliance Built In, Not Bolted On

Designed for financial-grade operations, Sitemule enforces SOX-compliant separation of duties, secure deployment workflows, and user authentication directly on IBM i.

200 transactions or 200 million in lightspeed

Modern Workloads. Legacy Stability.

Whether you're handling 200 transactions or 200 million, Sitemule keeps performance high, infrastructure simple, and your IBM i investment protected for the long term.

Use Cases

Modern Performance for Legacy-Critical Systems

A financial institution relies on IBM i to process millions of transactions daily - but slow integration and compliance risks hold back innovation. With Sitemule Enterprise, they run RPG and COBOL apps as secure web services, publish APIs in real time, and automate compliance-ready reporting. IT delivers faster, without rewriting a single line of legacy code.

 

Accelerate transformation without disrupting operations or sacrificing compliance.

High-Speed Data Exchange in Logistics

A global logistics company needs to sync inventory data between warehouses, webshops, and ERP in near real time. Previously, siloed systems and batch processes caused delays. By deploying Sitemule Enterprise, their IBM i applications now communicate via REST and JSON across all systems - streamlining fulfillment and reducing response time by 40%.


Keep operations moving with real-time integration on your existing platform.

Scaling Without Rebuilding

A major clearinghouse reaches performance limits during peak trading hours. Traditional RPG programs couldn't handle the load without rewriting their core systems. With Sitemule Enterprise, they activate thousands of concurrent jobs and scale securely - achieving a tenfold increase in throughput, all while retaining their existing IBM i structure.


Unlock scale and speed without abandoning proven architecture.

About Sitemule Enterprise

Build a Service-Based Architecture for Continuous Innovation

 

Sitemule Enterprise represents the evolution to a fully modern, service-oriented platform. It marks a decisive shift toward a service-based architecture driven by DevOps principles, enabling organizations to modernize sustainably and position IBM i at the heart of their digital ecosystems. This platform transforms the mindset from isolated modernization projects to a continuous, scalable, and collaborative transformation process.

 

Native Web and Application Server

Sitemule Enterprise, powered by IceBreak Engine, runs directly on IBM i (AS/400), eliminating the need for third-party platforms, middleware, or external servers. This ensures seamless integration, easier system management, and greater reliability. Modern web applications, APIs, and services run alongside RPG, COBOL, and SQL programs, maintaining decades of proven business logic while expanding capabilities into a modern web-based environment.

 

Bridging Traditional and Web Technologies

Through the Sitemule Enterprise, traditional IBM i languages - RPG, COBOL, C, and CLP - gain the ability to interact seamlessly with modern web technologies. Although these languages are not inherently object-oriented, Sitemule introduces object-like functionality through precompiled wrappers, simplifying complex processes and enabling structured, scalable API interactions. This model allows developers to build sophisticated, interactive applications while maintaining the efficiency of the IBM i environment.

 

Microservices and Domain Architecture

Sitemule Enterprise utilizes microservices and web services as the foundation for scalable, modular applications. Domain segregation supports a maintainable, flexible system structure where each component evolves independently. This organized approach decomposes monolithic architectures into bounded domains, increasing agility, resilience, and scalability while reducing development and maintenance costs. The Domain Model Definition provides a clear and adaptable blueprint for defining and managing domains.

 

Modern Development Integration

The platform offers advanced tools and frameworks that appeal to a new generation of developers. Native integration with modern front-end technologies, including Angular, React, and Vue.js, ensures IBM i stays relevant and competitive in today's development landscape. Service Programs, Db2 Files, Stored Procedures, UDFs, SQL Scalar Functions, and Web services are easily published as RESTful APIs with built-in OpenAPI documentation, simplifying integration and interoperability across systems.

 

Performance and Scalability

Intelligent load balancing and multithreaded job management dynamically distribute workloads across hundreds of concurrent sessions. This delivers faster response times and efficient resource use with stable operation even under heavy system load. Applications scale smoothly across on-premises and cloud environments, supporting millions of transactions while maintaining consistent performance.

 

Enhanced Security and Compliance

The platform upholds IBM i's strong security model and compliance standards, including SOX. Security is deeply embedded throughout the IceBreak Engine, with applications running under IBM i user profiles to enforce controlled access to system resources. Authentication options include SSL/TLS, OAuth, LDAP, Active Directory integration, IBM i native authentication, and session-based authentication. All communication is protected using SSL/TLS encryption, and custom security policies can be implemented to meet specific requirements. Strict separation between development and production environments protects data integrity, and IBM i's inherent reliability ensures compliance with enterprise and industry security standards.

 

Developer Tools and Capabilities

Developers benefit from web-native debugging, real-time monitoring, and structured logging. Precise troubleshooting is available through Visual Studio Code or the native 5250 environment. A powerful precompiler extends RPG, COBOL, and SQL with modern capabilities, enabling teams to build sophisticated, secure applications that leverage IBM i's native performance.

 

Operational Simplification

By consolidating workloads on IBM i, the platform simplifies operational management and enhances governance. This decreases reliance on fragmented external systems and supports ongoing innovation through DevOps automation.

 

Organizations achieve sustainable modernization with a service-based architecture guided by DevOps principles. Complexity is reduced by removing dependence on external platforms. Components evolve independently through microservices design. Modern frameworks and development practices attract new talent. Seamless integration across the enterprise provides full interoperability. Intelligent resource management delivers improved performance. Governance is maintained without compromise. Innovation becomes a continuous strategic process rather than a one-time task. The result is a future-ready platform that balances performance, security, and flexibility.

 

Implementation Timeline

The transformation to a fully service-oriented, DevOps-driven architecture is a continuous, strategic process that creates a foundation for scalable digital growth in the years ahead, with ongoing improvements and innovations delivered regularly.

 
A Unified Modernization Platform

Build a cohesive and future-ready modernization and transformation journey through four tightly integrated modules:

 

  • Sitemule Platform speeds up transformation by enabling quick migration to the web in days. 

  • Sitemule Workspace enhances usability by modernizing the user interface within weeks.

  • Sitemule Architect improves application design using domain-driven methodologies over months. 

  • Sitemule Enterprise finalizes the evolution by embedding a service-based architecture that reshapes long-term system strategy.

 

Together, these modules safeguard business continuity while unlocking higher levels of agility, collaboration, and scalability - positioning IBM i not as a legacy constraint but as a resilient and strategic foundation for the future.
