Mainframes are typically used by large-scale industries to perform/process their critical business applications. Earlier, these mainframes used to occupy more space and a separate cooling systems had to be provided to keep these mainframe systems cool. However, now a days, these computers are in smaller in size with capability of giving high computing performance. Based on the business requirements, mainframes have certain advantages and disadvantages.
- Mainframes can process massive amount of data at a reliable speed for years without any interruption.
- They handle large volumes of data for storage as well as for processing.
- All the applications and data are stored in a single mainframe such that it is easier for admin to administrate all applications.
- Mainframes acts as a central computer that can alone finish the work of some hundreds of smaller PCs, that eventually helps in lowering the administrative and management costs.
- Mainframes are more stable than other computers.
- Multiple operating systems can run mainframes such that it allows organization to run multiple processes with a reliable speed, security and operating power.
- Mainframes allow users to access data from remote terminal devices, that doesn’t have any processing capabilities.
- You can also design web based applications with security features.
- Mainframe computers are costlier.
- Mainframes occupy more space as well as generate more heat and require cooling devices to keep mainframe computers cool.
- Installation of mainframes is complex because of their devices are different from regular devices set up.
- More attention is required while operating.
These advantages and disadvantages would help you decide whether mainframes are really needed for your business/firm or no.
