buy something in a supermarket, use a mobile phone, make
an online payment, attend an entertainment event, the
chances are that the transaction is processed on a
Ticketing Systems, Stock market, Credit card
verification system all are accessing a Mainframe
Computer every time you use.
Many of today's busiest Web sites store their production
databases on a mainframe host. New mainframe hardware
and software products are ideal for Web transactions
because they are designed to allow huge numbers of users
and applications to rapidly and simultaneously access
the same data without interfering with each other.
At VISA, the San
Francisco-based credit card company process 145,000
transactions per second in 200 countries around the
Citi Bank uses System Z servers to process 150,000

Wallmart, Kenya Power, Tesco, HSBC, Indian Railways,
ICICI Bank, Vodafone, Swiss Reinsurance, AIG, Coca Cola,
Reserve Bank of India, DHL, Ford, HDFC, NASDAQ, Nike,
Union bank, UPS, United States Postal Service are some
of the clients who owns and uses a mainframe computer.
Applications of Mainframe Computers
Corporations use mainframes for applications that depend
on scalability and reliability. For example, a banking
institution could use a mainframe to host the database
of its customer accounts, for which transactions can be
submitted from any of thousands of ATM locations
servers have reported an 'Mean Time to Failure' of 40
The recent Mainframe Systems Z series are designed to
provide an availability of 99.999%.
Who uses System Z
92 of the world’s top 100 banks, 23 of the 25 top US
retailers, and 9 out of 10 of the world’s largest
insurance companies run System z mainframe.
71% of global Fortune 500 companies are System z clients.
9 out of the top 10 global life and health insurance

Video. New Possibilities of IBM Z series
The mainframe survived
minicomputers, the client server, the web, Y2K and
the Mobile Phones. Today more than 10,000 mainframes still
run hundreds of thousands of enterprise applications for
business, finance and administrative systems and that’s
unlikely to change any time soon.
Do you know that 200 times
more transactions are processed daily by Mainframe
Systems than there are Google and Youtube searches
There are over 220 billion
lines of COBOL in existence, a figure which equates to
around 80% of the world's actively used code.
Mainframes process roughly 30 billion business
transactions per day, including most major credit card
