This article debunks common myths, showing why the iSeries is still a powerhouse.
Myth 1: AS400 is Outdated Technology
Many believe the AS400 is too old for 2025’s fast-paced tech world. However, the iSeries has evolved significantly since its launch. Running on modern Power Systems hardware, it supports advanced features like cloud integration and AI. Its operating system, IBM i, receives regular updates, ensuring compatibility with new technologies.
Far from outdated, the AS400 powers critical applications globally. United Techno’s IBM iSeries AS400 modernization services transform legacy applications into web or mobile-friendly versions, proving the iSeries is a modern, capable platform.
Myth 2: AS400 Lacks Integration Capabilities
A common myth is that the AS400 can’t integrate with modern tools like cloud platforms or APIs. In reality, the iSeries supports integration with technologies like Java, Python, and REST APIs. Businesses can connect AS400 applications to cloud services like AWS or Azure, enabling real-time data sharing.
For example, a retailer can link its AS400 inventory system to a cloud-based e-commerce platform. United Techno’s IBM iSeries AS400 modernization services make these integrations seamless, ensuring the iSeries fits into hybrid IT ecosystems.
Myth 3: AS400 is Not Scalable
Some think the AS400 can’t handle growing workloads, labeling it inflexible. In truth, the iSeries is highly scalable, thanks to its virtualization capabilities and robust DB2 database. It can manage terabytes of data and thousands of transactions without slowing down.
For instance, a growing bank can scale its AS400 to process more customer transactions. United Techno’s IBM iSeries AS400 consulting services design scalable architectures, ensuring the system grows with your business in 2025.
Myth 4: AS400 is Insecure for Modern Threats
Security concerns are often raised, with critics claiming the AS400 is vulnerable to 2025’s cyber threats. However, the iSeries offers robust security features, including object-based access controls, encryption, and auditing. These protect against breaches and ensure compliance with regulations like GDPR.
Its isolated architecture makes it less prone to viruses. United Techno’s IBM iSeries AS400 Managed Services enhance security with regular audits and patches, keeping the AS400 safe in today’s threat landscape.
Myth 5: AS400 Skills Are Hard to Find
A persistent myth is that RPG programmers and AS400 experts are scarce. While demand for these skills exists, a vibrant community supports the iSeries in 2025. Online forums, user groups like COMMON, and training programs produce skilled professionals.
United Techno’s IBM iSeries AS400 consulting services provide access to experienced experts, while their IBM iSeries AS400 Support and Maintenance Services offer training to upskill your team, debunking the talent shortage myth.
Myth 6: AS400 is Expensive to Maintain
Critics argue that maintaining the AS400 is costly compared to modern systems. In reality, its cost-effectiveness is a strength. The iSeries’ integrated design reduces the need for multiple servers, lowering energy and admin costs. Its reliability minimizes downtime expenses.
For example, a manufacturer can save by running multiple applications on one AS400. United Techno’s IBM iSeries AS400 Support and Maintenance Services optimize costs through efficient resource management, making the iSeries affordable.
Myth 7: AS400 Can’t Support Modern User Interfaces
The green-screen interface of older AS400 applications leads some to believe it can’t support modern user interfaces. However, tools like IBM WebFacing and modern RPG allow developers to create web and mobile-friendly interfaces.
A logistics company, for instance, can transform its AS400 app into a tablet-friendly tool for drivers. United Techno’s IBM iSeries AS400 modernization services redesign interfaces, ensuring user-friendly experiences in 2025.
Myth 8: AS400 is Only for Large Enterprises
Another myth is that the AS400 is only for big companies with massive budgets. In truth, businesses of all sizes use the iSeries, from small retailers to global banks. Its virtualization and scalability make it adaptable for varying needs.
A small business can run a single AS400 server efficiently, while larger firms scale it for complex operations. United Techno’s IBM iSeries AS400 Managed Services tailor solutions for any business size, debunking this misconception.
Myth 9: AS400 Can’t Handle AI or Big Data
Some assume the AS400 can’t support AI or big data analytics. However, the iSeries integrates with tools like Python and TensorFlow, enabling AI-driven insights. Its DB2 database handles large datasets, supporting analytics for sales forecasting or customer behavior.
For example, a retailer can use AI on the AS400 to predict demand. United Techno’s IBM iSeries AS400 consulting services guide businesses in adding AI and big data capabilities, proving the iSeries’ versatility.
Myth 10: Replacing AS400 is Better Than Modernizing
Many believe replacing the AS400 with new systems is easier than modernizing it. However, its backward compatibility allows legacy applications to run on modern hardware, saving the cost of full replacements. Modernization adds features like cloud access while preserving investments.
United Techno’s IBM iSeries AS400 modernization services and IBM iSeries AS400 Support and Maintenance Services upgrade systems cost-effectively, showing that modernization is smarter than replacement.
