Why mainframe application performance is important?

Hello friends,

IBM mainframes dominate the mainframe market at well over 90% market share.
& as we know most of the banking systems uses the mainframe technology as front end as well as back end. Now a days some of them are using GUI at the front end designed by using .net, java, php or any other system, but at the back end definatly they are using mainframe because for them maintaining the customer information & there financial record is a major challenge. As mainframe can do it very nicely with high performance, they prefer for IBM mainframe.

   Form the above para u people come to know that how important mainframe is. In such a case it is also important to maintain the performance of mainframe application. 

    Form one of the survey, i observed following things- 

• 81 percent of global respondents say mainframe is already strategic or highly strategic to current and future IT plans
• 58 percent says mainframe is already or will be critical to cloud strategy
• 46 percent will spend more on mainframe software and 44 percent will spend more on services
• 44 percent already have or will be enabling mobile management of mainframe
• 54 percent want IT staff with cross-functional expertise.

        That’s why I was a little surprised to see one of our competitors announcing that mainframe application performance suddenly matters. Hasn’t it always?
        I came to IBM 10 months ago and, admittedly, was one of those people that didn’t think much about how “old” mainframe systems impact my use of modern applications. But most end-to-end systems from today’s large enterprises touch the mainframe in some way, that’s why it’s important to be able to measure transaction performance all the way from a web-front end through the back end mainframe.
     So what do u think about mainframe technology? is it really use in spite of being older one ?

IBM introduces new powerful mainframe computer

Hi Friends,

As u know mainframe god is IBM, who have invented mainframe computer, continuous there invention in the same field & now they have introduced new powerful mainframe computer. 
              IBM said its zEnterprise EC12 mainframe server is designed to help clients securely and quickly sift through massive amounts of data, meeting the demands of retail and other clients in the age of "Big Data." Running at 5.5 GHz, IBM said the microprocessor that powers the mainframe is the fastest chip in the world. Processing speed is 25 percent faster than the previous model.
Mainframes are used by corporate clients ranging from banks to chain stores. IBM says the new model could be used by retailers to manage online transactions and analyze clients' buying habits and then use the information to create a "more customized shopping experience," such as a custom coupon issued during a transaction.
          "Whether its retail or whether its transportation, making reservations, whatever it is, the system has been built really to help clients do those new types of new-age transactions," said Doug Brown, an IBM vice president of marketing.
         IBM says more than $1 billion was spent on research and development for the system at 18 sites worldwide, with most of it in Poughkeepsie, about 40 miles north of its headquarters in Armonk in Westchester County.
         The new mainframe is being promoted as one of the most secure systems ever with a tamper-resistant cryptographic co-processor to provide privacy for sensitive transactions.
           IBM has been focusing on its software and services divisions, which are more profitable than selling the mainframe computers that made the company famous decades ago. But the sales of those mainframes help feed demand for IBM services.

mainframe for today & tomorrow

Hi friends - -

In this post i will discuss some of the important facts about mainframe, because of that only it is most popular in today's world, & hope for feature also..

                         Today, mainframe computers play a central role in the daily operations of most of the world's largest corporations, including many Fortune 1000 companies. While other forms of computing are used extensively in business in various capacities, the mainframe occupies a coveted place in today's e-business environment. In banking, finance, health care, insurance, utilities, government, and a multitude of other public and private enterprises, the mainframe computer continues to form the foundation of modern business.

                      The long-term success of mainframe computers is without precedent in the information technology (IT) field. Periodic upheavals shake world economies and continuous— often wrenching— change in the Information Age has claimed many once-compelling innovations as victims in the relentless march of progress. As emerging technologies leap into the public eye, many are just as suddenly rendered obsolete by some even newer advancement. Yet today, as in every decade since the 1960s, mainframe computers and the mainframe style of computing dominate the landscape of large-scale business computing.

Why has this one form of computing taken hold so strongly among so many of the world's corporations? In this section, we look at the reasons why mainframe computers continue to be the popular choice for large-scale business computing. The mainframe owes much of its popularity and longevity to its inherent reliability and stability, a result of continuous technological advances since the introduction of the IBM® System/360™ in 1964. No other computer architecture in existence can claim as much continuous, evolutionary improvement, while maintaining compatibility with existing applications.

                        The term mainframe has gradually moved from a physical description of IBM's larger computers to the categorization of a style of computing. One defining characteristic of the mainframe has been a continuing compatibility that spans decades.

• The S/360: A turning point in mainframe history
  When did mainframe computers come into being? Mainframe development occurred in a series of generations starting in the 1950s. In those days, mainframe computers were not just the largest computers; they were the only computers and few businesses could afford them.
• Mainframe architecture: Secure, compatible, and still evolving
  An architecture is a set of defined terms and rules that are used as instructions to build products. Each generation of mainframe computers has included improvements in architecture, while remaining the most stable, secure, and compatible of all computing platforms.
• Mainframes in our midst: You use one every day
  Despite the predominance of mainframes in the business world, these machines are largely invisible to the general public, the academic community, and indeed many experienced IT professionals. Instead, other forms of computing attract more attention, at least in terms of visibility and public awareness. That this is so is perhaps not surprising. After all, who among us needs direct access to a mainframe? And, if we did, where would we find one to access? The truth, however, is that we are all mainframe users, whether we realize it or not.
• What is a mainframe? It's a style of computing
  Although the term mainframe first described the physical characteristics of early systems, today it can best be used to describe a style of operation, applications, and operating system facilities.
• Who uses mainframes and why do they do it?
  So, who uses mainframes? Just about everyone has used a mainframe computer at one point or another. If you ever used an automated teller machine (ATM) to interact with your bank account, you used a mainframe.
• Mainframe workloads: Batch and online transaction processing
  Most mainframe workloads fall into one of two categories: Batch processing or online transaction processing, which includes Web-based applications.
• Roles in the mainframe world
  Mainframe systems are designed to be used by large numbers of people. Most of those who interact with mainframes are end users— people who use the applications that are hosted on the system. However, because of the large number of end users, applications running on the system, and the sophistication and complexity of the system software that supports the users and applications, a variety of roles are needed to operate and support the system.
• What are mainframe operating systems?
  In simplest terms, an operating system is a collection of programs that manage a computer system's internal workings— its memory, processors, devices, and file system. Mainframe operating systems are sophisticated products with substantially different characteristics and purposes. 

I hope  i have covered most of the import thing about mainframe
