What is a Mainframe System?
Our primary focus is on the term Mainframe, as the name implies it is high-speed general purpose computer used for the large storage capacity. So there are basically four factors on which mainframe computer intend from large size, provide high reliability level, processing power is also high and the amount of storage. Commonly use for the large organization that are providing use of personal computer to each different user which requiring high volume of data processing. There are some of the features that are serve by mainframes which are common among all the vendors. Also have the ability to run multiple operating systems. A single mainframe can replace hundreds of servers.
Systems were first appeared in 1950s and the vendors of mainframe computers are IBM, Hitachi and Amdahl. Mainframe computers dominate the large-scale business computing. Now they are playing a central role in the daily operation of today’s world.
Some of the relevant things we must know about Mainframe Systems
Mainframe systems are still being purchased
According to BMC survey, there are still thousands of users using mainframe computers. There relevancy is on the top in the IT sector even though the recession put a dent to this sector. Many of the data centers and big organisation’s managers using them and many of them are planning to buy because they are appearing to coming back with economy. IBM is constantly updating mainframe operating systems and the major subsystem so this is the global factor that are boosting the need of these systems.
Mainframe is a cloud computer
The term computing in clouds mean using resources and software as services without worrying about what they come from. So mainframe systems will recognize as built in computing. So this include the idea of provision that can be used later and returned.
Mainframes are efficient computing platforms
Efficient computing platforms in terms of utilizing memory, storage and peripherals. Lets take an example the z/OS dispatcher quickly find the next unit of work waiting for a processor and IBM introduced WLM game and by using that game technicians set the performance goals and to achieve these goals resulting mainframe utilizing 85% of computing resources.
Mainframe systems are up to date and secure.
Many vendors say that mainframe is the old technology which is absolutely wrong, they are growing with very competitive high speed and fast caches. CPUs of mainframe systems provide sophisticated optimization feature like pipelining and keep supporting advanced technologies and modern languages such as C++ and Java. If we talk about security then there function and resources are protected through inviolable security. They are not only provide security administration to centralized structure rather support RACF feature introduced by IBM to keep two or more databases in sync. RACF stands for Resource Access Control Facility to ensure no one will able to login in the mainframe user without having authenticate permission. It also offers full suits of cryptography which emphasis encryption, decryption, hashing, masking and so on.
