 Mainframe is original cloud!

Get this all the time when teaching university kids on Cyber Security, Audit, Project Management. Especially when I tell them that we were in Cloud Computing in 1990s. Everyone gets surprised and when I start telling them old and new it starts making sense.

Essentially, then, mainframes were the original cloud. Going back decades, mainframes allowed companies to build cloud infrastructure “avant la letter” (which is a fancy way of saying “before the term cloud infrastructure existed”).

Baby Boomer, Generation X and Y are already in love with mainframe. Majority of Generation Z still don't know much about Mainframe and its capabilities like availability, LPAR, RACF and ability to segregate storage and compute. IBM is working hard and I think Z15 will bring Generation Z closer to Mainframe.

The mainframe is a workhorse. Yet, its power and potential are hidden from most people who work in the modern cloud. This is surprising because there’s a good argument to be made that, given its power and scalability, coupled with its support for a large number of concurrent users, the mainframe was the cloud before there ever was a cloud.

However, the technology is practically unknown among younger developers, mostly due to cultural reasons and a lack of historical awareness. That more people are not taking advantage of the tremendous opportunities at hand is a misfortune. When it comes to mainframe computing, there’s a lot of interesting technology to be learned and a good amount of money to be made. It’s just a matter of increasing awareness to do this. A good place to start is to redefine the narrative.

Information Security + Fair Value Accounting + UBS Systems and Controls Failures

Information Security: Why Cybercriminals Are Smiling
Published: August 19, 2009 in Knowledge@Wharton

Hardly a week goes by without some new internet security snafu being reported. And with web usage exploding, expect to hear about a lot more. According to a new analysis from Forrester Research, the number of Internet users is forecast to grow 45% globally over the next four years, reaching 2.2 billion by 2013. More people online, more data to hack -- it's a cybercriminal's paradise. read more

Is It Fair to Blame Fair Value Accounting for the Financial Crisis?
Published in Harvard Business Review
Investors and corporate executives don’t agree on how to value distressed assets. But maybe they don’t have to. What was the primary cause of the current financial crisis? Subprime mortgages, credit default swaps, or excessive debt? None of those, says Steve Forbes, chairman of Forbes Media and sometime political candidate. In his view, mark-to-market accounting was “the principal reason” that the U.S. financial system melted down in 2008. read more

Regulation of the U.S. financial sector

The current regulatory environment worldwide is one that demands that enterprises take every step to ensure the integrity of their finances, their data, their processes, and their employees. Legislators in virtually every nation have promulgated laws that mandate higher levels of corporate governance, risk management, and compliance. From the Sarbanes-Oxley Act (SOX) in the United States, to Bill 198 in Canada, to Japan’s Financial Instruments and Exchange Law (J-SOX) , to Saudi Arabia’s CMA Corporate Governance.

There is plan in the making at White house. The plan would bring sweeping changes to the way financial markets are overseen, empowering federal regulators and limiting the amount of risk financial companies can extend. It also would allow the government to take over and break up large firms, boost consumer protections and push for changes in the way loans are securitized.
