The IBM i (formerly known as AS/400) stands out as the backbone of countless businesses and is known for its unmatched reliability, scalability, and security. For decades, it has been powering mission-critical applications across various sectors, from finance to manufacturing. However, as technology evolves at an unprecedented pace, many IBM i applications have struggled to keep up, becoming outdated, difficult to use, and costly to maintain. These legacy applications often face difficulty in integrating with modern technologies. LANSA resolves these issues with professional low-code.

LANSA provides a comprehensive suite of developer tools designed to assist businesses in rapidly implementing new and advanced software solutions. From enhancing user interfaces to improving integration and reducing maintenance costs, LANSAโ€™s solutions enable businesses to meet the demands of todayโ€™s digital landscape.

The Legacy and Evolution of IBM i

Since its introduction in 1978, System/38 has been a midrange computer with options tailored for general businesses and service provisions for small businesses. IBM launched the AS/400 in 1988, which underwent several changes before becoming the i series in 2000, the System i in 2006, and eventually, IBM i Power Systems in 2008. Embraced across various sectors, IBM i has played a crucial role in corporate computing due to its reliability, security, and integrated DB2 database. It facilitates essential functions like production planning, quality control, and inventory management.

Over the years, IBM has rebranded its operating system and server multiple times to adapt to changing business requirements, showcase new technologies, and differentiate the platform within IBM’s portfolio.

The IBM i platform offers numerous valuable features for business environments. Its AS/400โ€™s integrated architecture simplifies system management by combining hardware, software, and operating system components into a unified environment. This integration enhances overall efficiency and reduces complexity.

AS/400 is known for its high reliability and availability features, such as hardware redundancy, error detection, and correction mechanisms that contribute to minimizing downtime and providing continuous operation. This also has strong security features, including user authentication, authorization controls, and auditing capabilities. The security model is integral to the systemโ€™s design, delivering a secure computing environment for sensitive data and applications.

Moreover, IBM i systems are scalable, allowing organizations to expand their computing resources as needed. These features collectively establish IBM i an indispensable platform for modern businesses.

Key Challenges Faced by Businesses Using Legacy IBM i Systems

While legacy IBM i systems have been the backbone of countless businesses for their daily operations for years, they now present significant challenges in keeping pace with todayโ€™s constantly evolving digital landscape. From outdated software and integration problems to mounting security concerns and talent shortages, businesses relying on these legacy systems face a range of issues that can hinder their growth and competitiveness. Letโ€™s take a look at some of the biggest issues faced by numerous organizations using legacy IBM i systems:

  • Legacy Software: One of the primary challenges companies face while working with legacy IBM i hardware and software is performance bottlenecks, which lead to costly downtime and lost productivity. These outdated systems often struggle to meet the demands of today’s fast-paced business environments. Many businesses that continue to operate with legacy systems often lack the flexibility and scalability to support modern business processes, making maintenance and upgrades exceedingly difficult. This outdated legacy software impedes business growth and efficiency, slows operations, and causes frustrating delays, potentially leading to costly downtime and lost productivity.
  • Integration: Integrating existing IBM i applications with modern software and platforms poses difficulties for many companies. The architecture of these legacy systems was not designed with today’s interconnected, API-driven ecosystems in mind, making integration a complex and time-consuming process. The lack of integration capabilities makes it difficult for companies to streamline workflows, share data across platforms, and incorporate new technologies. As a result, companies continue to work with outdated systems, leading to data silos, inefficiencies, and missed opportunities for automation and innovation.
  • Security Concerns: With the increasing prevalence of cybercrimes, maintaining data security has become vital for every company. Legacy software is inherently vulnerable due to its outdated nature, which can lead to significant security risks for your organization. With time, cybercriminals’ skills have also advanced, and to protect against them, companies require modern security measures. Without regular patches and updates, these systems can become easy targets for cyberattacks, exposing sensitive business and customer data to potential breaches. Legacy software lacks advanced security features such as firewalls and encryption protocols, making it vulnerable to security breaches, data leaks, and malware attacks. Moreover, cybercriminals can exploit these weaknesses and hack the systems. Thus, It is critical to update your IBM i application with the latest security updates and utilize advanced security measures to safeguard your business and customer data.
  • Cost of Maintenance: Maintaining and upgrading legacy IBM i applications can be costly for businesses. The expenses associated with hardware replacements, software updates, and ongoing technical support can strain a companyโ€™s budget. As these systems are outdated, they often require frequent repairs and maintenance, which drives up costs. Additionally, the specialized skills required to support legacy IBM i applications are becoming rare, making finding qualified personnel difficult and expensive. Not to mention, the software updates and ongoing support can drain the companyโ€™s budget. In some cases, the costs of running these applications can be more expensive than the cost associated with replacing your software.
  • Talent Shortage: Another significant challenge is the scarcity of IBM i experts in the job market. It is rare to find skilled programmers who can manage, program, and maintain these legacy systems, as many of the experienced professionals are near retirement. Companies have a hard time recruiting, training, and retaining staff with the essential skills to manage their IBM i resources. Often, knowledge of legacy IBM i applications within a company resides with one individual and is difficult to document. When faced with the need to replace that team member without an ample handover period, this becomes a serious continuity concern.
