For a long people have been anticipating the end of mainframes; however, it continues to lead the technological solutions, and it appears that its days are far from over. Undaunted by the new workhorses of the enterprises and acceleration in the cloud, technology is still thriving in the market. But before we further discuss about mainframe's future in the IT sector, we should first attempt to understand what is it, its history, and then move on to its market segmentation and its future in the market.
Basic Concept of Mainframe
Since its introduction in the 1950s, mainframes are high-performing computers consisting of large memory and processing power that allows the calculation of billions of problems in real-time. It is higher performing system than PCs, workstations, and minicomputers in many ways. They run in the background of immense and critical data processing tasks. It is a technology where requests received are processed faster and shared with related processor cards. It is majorly used in IT companies, Walmart, NASA, and a lot of other sectors that require huge data to be processed. Therefore, it wouldn't be an exaggeration to say that it will be used more in the coming days.
History of Mainframe
The tech giant IBM introduced large-scale computers in the 1950s with the 700 series of machines. After much research and development, CBOL, Fortran, PL1, and C were added as programming languages, and system 360 enabled time-sharing and multiple virtual storages. In the 1970s, the new ESA version was extended to 31 bits, and parallel sysplex and data sharing were introduced, resulting in better load balancing and 24X7 availability and failover. Moreover, at the beginning of the 2000s, Java, Linux, and s64-bit were invented, and post 2010 saw the emergence of APIs and REST services. During the same time, hardware was enhanced to support to support Java and C++ workloads. Many leading companies in the IT sector, such as IBM, BMC, and CA, continued their investment in the mainframes along with cloud-based products and Zowe.
Market Segmentation of Mainstream
Since its inception in the mid 20th century, mainframes have come a long way. These days, they have become an integral part of modern enterprises across the globe; nonetheless, many believed it to face some intense competition from the modern ERP solutions, AWS, and other cloud-based solutions. However, given its usability, which makes it more cost-effective, it will continue to gain more trust among companies. These latest technologies offer the most reliable, cheapest available system to businesses that have high workloads. Additionally, mainframes run at approximately 100 per cent CPU efficiency compared to Intel-based servers that require below 60 per cent utilization. This fact infers that though the cost of mainframes may be high, they offer a great return on investment. Consequently, many industries and enterprises, whether SMEs or big, view their future with mainframes. Let us look at the various market segments and trends that determine how businesses opt for mainframes.
