Pros and Cons Mainframe Computing

Mainframe computers perform complex and critical computing in large companies and governments around the world. Mainframe machine is quick, smart and capable of the advanced computer requirements necessary for the generation of our business infrastructure information technology and business goals.

The emergence of new computer technology has not reduced demand for primary production, as they offer unique benefits that make them one of the most reliable business technology.

Consider the features that make primary production a preferred computing platform, and also some of their failures.

Advantages of primary computing

High-level computers: One of the main characteristics of the primary software is their ability to process data and run high-speed applications. Business technology requires high speed input / output (I / O), more than raw computer speed. Mainframes deliver it in fact. Furthermore, since business technology also requires wide bandwidth connections, the primary production design is balanced in I / O performance and bandwidth.

Increased processing: Mainframe computers are supported by a large number of high-power processors. In addition, unlike other computers, I / O's primary producers relate to hundreds of servers, thus limiting the main processor only to application processing. This feature is unique for primary production and makes them better in processing.

Virtualization: Operating system can be divided into logical partitions (LPARs, also known as virtual machines). Each LPAR can run a server. Thus, one grid machine can do the work of a "server of the town" that uses a number of servers based on other platforms. Since all of these virtual machines are on a single processor in one box, the primary production effectively eliminates the need for a lot of other hardware.

Reliability, Availability and Service (RAS): RAS computer characteristics have often been some of the most important components of data processing. Mainframe computers show effective RAS characteristics in both hardware and software.

Mainframe systems are reliable because they can report, report and self-recover from system problems. Furthermore, they can improve without interfering with the entire work environment, so most applications are available.

The main application services mean that they make it easy to diagnose and diagnose problems that help fix problems in a short period of time and with a low downtime.

• Security: Because the main applications are specifically designed for large organizations where data confidentiality is important, the main application computers have extensive capabilities for securely storing and protecting data. They provide a secure system for the number of applications that all get access to confidential information. Mainframe security often integrates multiple security and monitoring services: user authentication, audit, access control and firewalls.

• High-end flexibility: Stabilization of the computer platform is the ability to perform even as processors, memory and storage are added. Mainframe computers are known for flexibility in both hardware and software. They easily run many tasks of different complexity.

• Continuous compatibility: Continuous compatibility is one of the most popular features of the main software. They support programs of different ages. Mainframe computers have been updated many times and continue to work with many composite old, new and new software.

• Long-lasting performance: Mainframe computers are known for their long-standing performance. Once installed, work system systems for years and years without any significant problems or downtime.

Disadvantages of primary production
One of the main primary transactions is their cost. Hardware and software for highways are clearly expensive. However, compared with the cost of other security leads, IT management, virtualization, etc., the cost of primary production is significantly reduced.

Secondly, primary production hardware jobs more space than other computers. This large space could be a constraint for small businesses. But this problem is not as serious as once. Compared with previous machines, today's main applications are small.

Finally, you need high-end talent to work with large electronic equipment. You can not process primary production without any special training. However, as one qualified administrator can serve a large group of users with primary production, using primary production that significantly reduces human costs and, consequently, offers significant employee costs.
