Mainframe computers have been around for more than half a century, and they have been crucial to the success of many of the world’s largest businesses. Even though they have been overshadowed by modern technologies, they have managed to survive the test of time. Mainframes have remained relevant in the digital age due to their enormous processing power, uninterrupted uptime, and virtualization capabilities.
Mainframes are still used by many large institutions, including banks, insurance companies, government agencies, and airlines, to mention but a few. They are known for their unmatched processing power, which enables them to handle large volumes of data effortlessly. In addition, mainframes can work seamlessly, with multiple tasks being processed at the same time without slowing down the system. Mainframes are also reliable since they offer uninterrupted uptime, which is vital for organizations that need to offer their services around the clock.
One of the significant advantages of mainframes over other computing systems is their virtualization capabilities. Mainframe virtualization refers to the creation of a virtual system inside the mainframe system, allowing users to run multiple operating systems and applications on a single machine. This provides organizations with more flexibility, as the mainframe can run a mix of applications that run on different operating systems. Moreover, it reduces the amount of money spent on hardware and software.
An excellent example of why mainframes remain relevant is the role they play in banking. According to IBM, 87% of all credit card transactions, 29 billion ATM transactions, and 4 billion passenger flights annually are powered by the mainframe computer. Furthermore, the transaction processing of all four major credit card companies, including Visa, MasterCard, American Express, and Discover, is handled by mainframes.
Another example is the government, which still relies heavily on mainframes. For instance, the Social Security Administration uses mainframes to process payments to over 66 million beneficiaries monthly. Similarly, the US Department of Homeland Security uses mainframes to provide critical security services, including biometric identification systems relied upon by border patrol agents.
In conclusion, mainframe computers are still relevant in today’s digital age due to their incredible processing power, unmatched reliability, and virtualization capabilities. These features make them ideal for large institutions that need to process large volumes of data and require uninterrupted uptime. Mainframes are relied upon by many industries and organizations worldwide, and they will continue to serve their purpose in the future.
