The document highlights the importance of COBOL in modern IT and its significant role in daily transactions across various industries. It discusses the need for modernization of COBOL applications, the challenges posed by retiring developers, and the ongoing reliance on mainframes for critical business functions. Additionally, it provides resources and information about upcoming events in the data analytics and business intelligence community.
![“Why Do Mainframes Matter
Today?”
• “Mainframes host critical core IT for: 92 of the world’s top 100 banks; 23 of the
25 top airlines; 10 of the world’s top 10 insurers; and 71 percent of Fortune
500 companies.
• Mainframes run 30 billion transactions per day, hold 80 percent of the world’s
business data and handle 90 percent of all credit card transactions.
• Mainframes host more transactions daily than Google (1.3 million/second on
CICS vs. 68,542/second on Google), including 55 percent of all enterprise
transactions.
• Mainframes consume only 6.2 percent of worldwide IT spend. Yet, they run
68 percent of production workloads and an estimated 220Bn lines of code,
with the highest levels of security and reliability.” [15/Mainframe Matters]

- 35. Discussion 1. Can we avoid fully modernizing COBOL applications? (modernization involves much more than just code changes) 2. Do we want to be moving these applications fully into the cloud? If so, how so? Gradual vs Big Bang vs starvation? 3. What will happen as more COBOL engineers retire and fewer engineers are available to support these applications? 4. Should businesses invest in training COBOL developers? 5. Is modernization really necessary and/or desired? 6. Are we heading toward a crash in IT? If yes, what would it look like and when would it happen? 35
