Sitemule Modules & Engines - Complete IBM i Modernization Ecosystem

Eight purpose-built modules and four native runtime engines transform legacy IBM i systems into unified, browser-based workspaces without middleware or rewrites

Sitemule is a comprehensive modernization ecosystem for IBM i environments that transforms legacy systems into a unified, browser-based workspace. It bridges the gap between traditional IBM i applications and modern web technologies, running natively on IBM i and eliminating the need for middleware or external infrastructure.

Our innovative Modules

The Sitemule ecosystem consists of eight purpose-built modules, tightly integrated and presented by the Sitemule Platform.

The Sitemule Platform serves as a foundation for the modules and, at the same time, combines IBM i systems, third-party solutions, and modern applications into a single, unified, browser-based workspace, powered natively on IBM i. Each module covers specific areas in a modernization and transformation journey.

Modules cover everything from visual and functional modernization in a browser-based, user-friendly environment to the introduction of a modern service-based architecture with domain-driven applications, AI context-specific guidance, and detailed documentation for both technical staff and end users.

Together with the Sitemule Platform, the modules can be deployed individually or combined, allowing organizations to tailor modernization initiatives to their specific needs.

"These engines deliver relevant functionalities as runtime services to the modules. Long established as trusted standalone products in the IBM i community, they now operate within the Sitemule Platform as fully integrated runtime engines."

Our powerful Engines

The Sitemule ecosystem is built on four high-performance engines, refined over two decades of development. These engines handle everything from web serving and microservice-driven architecture to screen transformation, messaging, and system monitoring.

The engines deliver relevant functionalities as runtime services to the modules. Long established as trusted standalone products in the IBM i community, they now operate within the Sitemule Platform as fully integrated runtime engines.

Our successful Solution

We turned our well-established products into engines and created a series of innovative, purpose-built modules that modernize and transform our customers' solutions.

We released essential functions as open source and engaged developers in the ibm i community.

We offered our engines to our partners as replacements for outdated technologies and as enhancements to their solutions, strengthening our partnership.

With Sitemule, we have successfully created and delivered a realistic, scalable modernization and transformation path for the IBM i.

FAQ & Takeaways

What is the difference between modules and engines in IBM i modernization?

In IBM i modernization, modules are application-layer components that provide specific business capabilities like screen transformation, API development, or documentation management. Engines are runtime infrastructure components that execute applications, manage communication, and monitor systems. Modules define what you want to accomplish; engines provide the native IBM i execution environment that makes it happen without external middleware.

Can IBM i modernization modules be deployed independently or must they work together?

Modern IBM i modernization platforms support both independent and integrated module deployment. Organizations can start with specific capabilities like 5250 screen modernization or API development, then add modules as needs evolve. This modular approach allows incremental modernization without disrupting existing operations, letting teams address high-priority areas first while maintaining flexibility for future expansion.

Why do IBM i modernization platforms run engines natively instead of using middleware?

Native IBM i execution eliminates middleware overhead, latency, and integration complexity. When runtime engines operate directly within IBM i, they access Db2 databases without ODBC/JDBC layers, inherit native security controls, and avoid external server dependencies. This architecture delivers faster performance, simpler management, stronger governance, and lower total cost of ownership compared to middleware-dependent approaches.

What do the eight Sitemule modules cover in IBM i modernization?

Sitemule's eight modules address the complete IBM i modernization lifecycle: visual and functional modernization transforms 5250 screens into browser-based interfaces, service-based architecture enables API and microservice development, domain-driven applications support modern development patterns, AI-powered guidance provides context-specific assistance, and comprehensive documentation serves both technical staff and end users. Each module integrates with the Sitemule Platform to create a unified workspace running entirely on native IBM i.

How do Sitemule's four engines support the platform modules?

Sitemule's four engines - IceBreak (web server and application execution), IceCap (5250 screen transformation), BlueSeries (email, SMS, FTP communication), and BlueNote (real-time monitoring) - provide runtime services that all modules leverage. Originally proven as standalone IBM i products over two decades, these engines now operate as integrated infrastructure within the Sitemule Platform. This architecture means modules inherit battle-tested reliability, native performance, and direct Db2 integration without requiring external middleware or servers.
