BM i continues to power mission-critical business systems across distribution, manufacturing, finance, and retail. In 2026, the conversation is no longer about replacing IBM i — it’s about modernizing IBM i in practical, sustainable ways.
The good news? Modernization doesn’t require abandoning RPG or rewriting stable applications. The most successful organizations are enhancing their IBM i environments through strategic IBM i integration, API enablement, and cloud-ready infrastructure.
Here’s what that looks like today.
IBM i Modernization Starts with Integration
For many organizations, modernization begins with a simple question:
How do we connect our IBM i to modern applications, web platforms, mobile tools, and cloud services?
The answer lies in building secure, scalable IBM i APIs that allow your existing business logic to communicate with the outside world.
By exposing core RPG programs as REST services, companies can:
- Integrate IBM i with web and mobile applications
- Connect to third-party SaaS platforms
- Support eCommerce and customer portals
- Enable real-time data exchange
- Extend legacy systems without rewriting them
This approach preserves the reliability of IBM i while expanding its capabilities.
Building REST APIs Directly in RPG
One of the biggest misconceptions in IBM i modernization is that middleware is always required. In reality, modern IBM i API toolkits allow teams to build REST APIs directly in RPG.
Benefits of RPG-based API development include:
- No need to move business logic off-platform
- Reduced integration complexity
- Faster development cycles
- Improved security control
- Lower infrastructure overhead
For IBM i teams, this means modernization without disruption.
IBM i Cloud Strategy: Hybrid Is the New Standard
Another major topic in 2026 is IBM i cloud strategy. Organizations are increasingly adopting hybrid models that combine on-prem IBM i systems with private or managed cloud environments.
Cloud-ready IBM i environments provide:
- Improved disaster recovery options
- Scalable infrastructure
- Reduced hardware lifecycle stress
- Greater operational flexibility
Modern IBM i cloud hosting isn’t about abandoning control — it’s about increasing resilience and scalability while maintaining performance.
Digital Transformation Without Rewriting Everything
IBM i digital transformation doesn’t require a “rip and replace” approach. In fact, rewriting stable RPG applications often introduces unnecessary risk.
Instead, leading organizations are focusing on:
- API-enabling existing applications
- Modernizing user interfaces
- Improving data accessibility
- Automating integrations
- Enhancing security and monitoring
This layered modernization strategy allows companies to innovate while protecting their most valuable systems.
Security and Compliance in Modern IBM i Environments
As IBM i systems become more connected through APIs and cloud integrations, security must evolve alongside modernization efforts.
Best practices include:
- Secure API authentication and token management
- Role-based access control
- Encrypted data transmission
- Continuous system monitoring
- Regular vulnerability assessments
Modern IBM i integration strategies must prioritize security from the start — not as an afterthought.
What Successful IBM i Teams Are Doing in 2026
The most forward-thinking IBM i teams share common characteristics:
- They treat IBM i as a strategic asset, not a legacy burden
- They invest in API enablement and integration tools
- They empower RPG developers with modern capabilities
- They adopt cloud strategically, not reactively
- They modernize incrementally, not disruptively
IBM i isn’t standing still — and neither are the organizations that rely on it.
The Path Forward
IBM i remains one of the most stable and powerful enterprise platforms available. The focus in 2026 isn’t replacement — it’s intelligent evolution.
By embracing:
- IBM i APIs
- RPG-based REST services
- Strategic cloud adoption
- Practical integration frameworks
Organizations can modernize confidently while preserving the reliability and performance they depend on.
If you’re evaluating your IBM i modernization roadmap this year, start with integration. It’s the most practical, cost-effective, and low-risk way to extend the value of your existing systems.
