Top Reasons Enterprises Are Prioritizing IBM iSeries AS400 Consulting Services in Their 2025 IT Strategy

Introduction

In 2025, enterprises are navigating a complex digital landscape where agility, security, and integration have become foundational to long-term success. While many organizations are embracing cloud-native platforms and modern SaaS solutions, a significant number still rely heavily on proven legacy systems like the IBM iSeries AS400.

Far from being obsolete, the IBM iSeries AS400 continues to power mission-critical operations in industries such as banking, manufacturing, logistics, and healthcare. However, leveraging its full potential in the modern IT ecosystem requires strategic modernization—and this is where IBM iSeries AS400 Consulting Services play a pivotal role.

In this article, we explore why enterprises are making these services a top priority in their 2025 IT strategy, key use cases, business benefits, and best practices for implementation success.

What is IBM iSeries AS400?

The IBM iSeries AS400, now officially known as IBM i on Power Systems, is a midrange computing platform renowned for its stability, integrated architecture, and long lifecycle. Originally introduced in the late 1980s, the platform continues to evolve and is used by thousands of global enterprises for high-volume transaction processing, database management, and backend operations.

Why Enterprises Still Rely on IBM i:

  • High reliability and uptime for mission-critical workloads

  • Integrated OS, DB2 database, and middleware in a single stack

  • Strong backward compatibility supporting legacy applications

  • Robust security architecture and workload performance

  • Scalable hardware infrastructure with proven cost-effectiveness

While IBM i remains a cornerstone for many enterprises, it requires modernization and integration to align with cloud-first, API-driven IT environments—making consulting services indispensable.

Key Use Cases or Scenarios

Organizations are engaging IBM iSeries AS400 Consulting Services to help bridge the gap between legacy reliability and modern IT demands. Here are some common scenarios where these services provide high-value impact:

1. Workflow Automation

Consulting teams help automate manual or batch-based AS400 processes by integrating them with modern tools such as ERP, CRM, and HRIS platforms—reducing human error and accelerating operational speed.

2. Real-Time Data Synchronization

Enterprises can’t afford data silos. Consultants enable real-time data integration between IBM i databases and external analytics tools, e-commerce platforms, or supply chain systems.

3. Hybrid IT Environments

Many businesses operate in hybrid environments where IBM i must coexist with cloud-native systems. Consulting services design and implement secure, real-time data exchange pipelines between on-prem and cloud infrastructure.

4. Legacy System Modernization

Modernizing green-screen applications, converting RPG codebases, or exposing legacy functions via APIs is complex—but manageable with experienced AS400 consultants.

5. Cloud Integration Enablement

Consulting teams help integrate IBM i workloads with public or private cloud platforms such as AWS, Azure, or IBM Cloud, ensuring seamless connectivity and secure data flow.

Benefits of Using IBM iSeries AS400 Consulting Services

Whether you’re looking to enhance stability or evolve functionality, IBM iSeries AS400 Consulting Services offer tangible business advantages.

Increased Productivity

Streamlined workflows and integrated systems reduce delays, eliminate duplication, and empower teams to work more efficiently.

Improved Scalability

Consultants help design systems that scale with growing transaction volumes, new service lines, or geographical expansion.

Cost Efficiency

Instead of investing in costly replacements, enterprises can optimize existing infrastructure while gradually modernizing—maximizing return on past investments.

Enhanced Security

Consultants bring a deep understanding of IBM i’s built-in security features, and can align configurations with modern data privacy and compliance requirements.

Competitive Advantage

By extending the life and capabilities of trusted systems, businesses can innovate faster and deliver better digital experiences—without starting from scratch.

Best Practices for Implementation

To extract full value from IBM i modernization and integration efforts, enterprises should follow these best practices:

1. Start With a System Assessment

Consultants should begin with a full audit of the current IBM i environment—workloads, dependencies, pain points, and business priorities.

2. Prioritize High-Impact Workflows

Target processes that directly impact customer experience or financial performance. These are typically the best candidates for automation or modernization.

3. Implement API-Led Integration

Rather than rewriting entire applications, expose IBM i capabilities via APIs. This allows legacy systems to interact with modern services without full replacement.

4. Use Phased Modernization

Avoid big-bang approaches. Gradual updates reduce risk and allow for better testing, change management, and knowledge transfer.

5. Monitor, Measure, and Optimize

Ongoing monitoring and performance analysis help track value delivery, ensure system health, and uncover new opportunities for improvement.

Why Expert Consulting Adds Value

While internal IT teams often have deep knowledge of IBM i, they may lack the specialized skills or capacity required for integration, modernization, and cloud-readiness. This is where expert consulting delivers measurable value.

A trusted partner like United Techno offers:

  • In-depth expertise in IBM iSeries AS400 architecture and modernization

  • Proven methodologies for legacy-to-cloud transitions

  • Custom API design and secure integration with cloud platforms

  • Legacy application enhancement and performance tuning

  • Ongoing support, training, and performance monitoring

By aligning technical improvements with business goals, consulting partners help enterprises future-proof their IBM i investments and drive digital growth.

Conclusion

As enterprises accelerate their digital initiatives in 2025, maintaining agility while preserving core system stability is critical. The IBM iSeries AS400 continues to serve as a reliable engine for many businesses, but modernization and integration are essential to keep pace with changing demands.

IBM iSeries AS400 Consulting Services enable enterprises to unlock new value from their legacy systems—improving productivity, security, scalability, and innovation without disrupting mission-critical operations.
