Companies that run on iSeries fall into verticals right from banking to the health sector, from manufacturing to distribution centers & retailers. Even Government sectors trust their data to the secure infrastructure of the AS400 system. If you ask our clients, 65% say they are running 85-100% of their workload and business applications on iSeries and the rest are planning to increase workloads on the platform. This simply reflects the enduring nature and the legacy of IBMi platform & clearly explains why you should invest in it.

    IBM AS400 iSeries is one of the most robust systems in the world. Out of all the application servers, IBM AS400 operating system has an incredible – uptime rate of 99.97%. That is why it is one of the most reliable and secure methods for every vertical.

    Even after three decades with more than seven lakhs+ application systems, as400 iSeries is installed in over 150 countries. The current AS400 programmers are not generally enthusiastic about replacing IBM AS400 / i-series with something else, which is yet to prove it’s worth.

    The importance of the IBM AS400 iSeries system has increased a few notches higher for enterprises, as it’s working well and able to avoid the necessity of yet-to-prove new technologies.

    Newcomers need to know that the IBM AS400 iSeries platform is the best business tool for over 30 years. And the fully integrated database of IBM AS400 iSeries comes with full system logging via journals that cannot be accomplished by any other system.

    Why IBM AS400 / iSeries Is Irreplaceable?

    Making an entry into the market 30 years prior and still, IBM AS400 iSeries is regarded as the most reliable and secure server worldwide. Hence, IT organizations are reluctant to move away from their dear IBM AS400 iSeries.

    For various industries like – insurance, banking, and manufacturing, data is their lifeline, and businesses generally don’t switch the servers or operating systems on which they are working for a long time.

    In the current scenario, when integration and development in IBM AS400 / iSeries are becoming much more comfortable, there is no point in neglecting this legacy system. Also, moving to something entirely new always poses a risk of uncertainty regarding performance and robustness.

    Even though the AS400 iSeries platform has heavy-hitting technology, people still have some misconceptions in their minds.

    Here, let’s try to clear the misconceptions and give you the reasons to invest in this advanced technology.

    AS400 Is Outdated:

    The software was created in 1988, and since then, it has been renamed several times, and renaming has not helped in changing the mindset that it is a modern platform. But the fact is, AS400 iSeries software and AS400 iSeries services are critical parts of many top organizations’ computing infrastructure worldwide.

    AS400 Talent Is Retiring:

    According to a few experts, the veterans on the as400 iSeries platform are reaching retirement age, and all their knowledge and expertise will go along them. But, they are unaware that there are several as400 development companies and on-demand developers of AS400 / i-series software, working with various top organizations worldwide.

    Just have a look at the pointers to know where AS400 iSeries is still used

    • Over 10,000 companies worldwide use AS400 iSeries technology as it exists within IBM to power their most critical applications. These companies work in various sectors like banks, healthcare, manufacturing, government agencies, and distribution centers.
    • The AS400 iSeries software is like an unsung hero. It is not used for general office functions or to increase employee’s productivity; instead, it handles heavy applications like ERP or health information systems.
    • According to the recent survey of AS400 iSeries software users, 39% of them manage their 75-100% workload through this software only.
    • Moreover, the statistics also indicated the importance of this platform in the future. As per statistics, 20% of the users are ready to increase IBM’s workload of IBMi web services.

    AS400 Software Performance with its Marketing Competitors

    When comparing the technology and scope, you need to be aware of the market or the application category it currently fits in.

    If you will resemble a user mobile application technology against a huge transnational server application, it is altogether in a different context.

    The sole purpose of their existence is other. The problem each of them solves is also different.

    For example, it is better to compare Android vs. iOS or Linux vs. Windows or even SAP vs. Oracle.

    Why AS400/iSeries is Still Considered?


    Never question AS400/iSeries software reliability. The AS400 iSeries is still recognized because maintenance problems associated with it are rare. As per IBM, AS400 iSeries developers experience only around 5.1 hours of unavailability per year, which counts to 99.99% uptime.


    Today, server security is more critical than ever, and the AS400 iSeries software has never been infected with similar viruses that affect other systems.

    Moreover, its object-based design has been the heart of power systems since the start, and still today, it’s the key to IT security since viruses often penetrate systems into data form and not objects.

    A large number of unattended organizations prove that automation is a feasible strategy for AS400/iSeries software. Large organizations with 2-4 servers are more likely to run alone in comparison to small organizations.

    Moreover, the decision of automation is not decided as per size; this depends upon the project.

    Percentage of Core Business on IBM AS400/iSeries:

    AS400 software is a critical platform for most organizations, as more than half of their core business runs on AS400 iSeries software. Without this platform, some organizations will struggle to run their businesses.

    What it means is, these organizations are running their business on AS400 iSeries software, not because other technologies are ignorant, but because only “IBMi” suits their needs.
