Mainframe power

Opposite is a quote from an article by Bob Reselmen which was published via LinkedIn.

It is useful in giving an insight into the value of mainframes to commerce in general, not just banking, even though many of the transactions are likely to have involved credit or debit cards.

The Power of the Mainframe

"The fact is that a mainframe is a monster when it comes to computation and processing transactions.

One mainframe can process 2.5 billion transactions daily.

That's the equivalent of 100 Cyber Mondays in a single day.

To give you a clearer idea of the immensity of scale,
keep in mind that Cyber Monday sales in 2018 were $7.9 billion.

This translates into a mainframe being able to handle a bit more than three-quarters of a trillion dollars
in transactions each day, which is almost twice the yearly GDP of Austria!" - Bob Reselman

Note - GDP is Gross Domestic Product
