I am sure that you might have heard about mainframes and the career prospects they offer. Do you know about the specialty of mainframes? Mainframes are very large computers mainly used for running mission critical and complex applications involved in activities like bulk data processing, financial transactions etc.
The huge servers are capable of supporting immense number of applications and input/output devices to simultaneously serve any number of users by the partitioning of resources. That is, it serves as a centralized depository of data which is connected to the users through work stations or terminals.
The origin of the mainframe can be traced back to the 1950′s which saw the emergence of the IBM 700/7000 series. Since then there has been a series of products evolving to accommodate the user requirements. Some of the initial drawbacks of mainframe that had been pointed were the lack of flexibility and the high cost.
Thus the IBM came up with the highly flexible IBM system/360 which used microcode to implement the machine instructions. The last in the spectrum is the Z series, introduced in the 2000s, equipped with massive scalability, better security and resiliency, intelligent workload management and business integration on a virtualized platform.
So many speculations were made about the future of the mainframes so far. The truth is that they will not become obsolete for a reasonably long time. The markets see an ever-time improvement in the sale of mainframes and boom in the training. This is because mainframes are still unsurpassable in their reliability and stability in processing information. No technology might have undergone such a lot of evolutionary changes as mainframes had.
They win over their competitors by the continuous evolution of their architecture to meet the demands of the user network at the same time maintaining compatibility with the existing applications.
System Z9, the latest in the series, has double the processing power and capacity, memory, MIPS and number of partitions than its predecessor. Virtualization technology enables the Z servers to run mixed workloads. Z/OS uses multiprocessing and multiprogramming for large-scale data management and I/O operations.
