Mainframes and the Cloud: Made for Each Other

April 2018 marked the 54th anniversary of IBM’s mainframes. It is uncertain if anyone could have ever predicted such a long and successful life for them. A quick historical sketch: IBM launched the first modern mainframe, IBM 360, on April 7, 1964. With 229,000 calculations per second, it was the mainframe that played a key role in taking mankind to the moon. Fast forward to the current era: multiple banks, the healthcare industry, along with the insurance and government sector, still continue to use mainframes. Mainframes might not be trending as the hottest technology of the decade, but they act as the backbone for these and various other industries due to their reliability, availability, security, and transaction processing speed.

Monitoring your service providers

Outsourcing has been the rage for years now, and the outsourcing of computing resources to the cloud leads the way. And why not? It allows you to increase efficiency (focus on core business activities instead of running a datacenter), cut costs (you don’t have physical datacenter costs), reduce risk (or pass it on to the third party), and scale when needed with (hopefully) minimal cost and fuss.

The need for modern mobile solutions for mainframe data centers

Today most CIOs, CTOs and IT experts are aware of the impact of digital transformation (DX) on their respective businesses and IT organizations. Disruptive technologies like Big Data, business analytics, cloud (computing and storage), digital payment, and more recently the algorithmic economy and the Internet of Things (IoT), have and are making their impacts felt. However, the most impactful of all DXs may very well be mobile.

Improving the Bank’s Bottom Line: Reducing Cost per Transaction

A few years ago, I invited a group of CIOs to become an Advisory Board for my company. Their role was to advise us on the direction the company should go, and how we should position our products and services most effectively from the perspective of the Fortune 500 CIO. To this day, we still engage our Advisory Board on many subjects.

A Brief History of (Mainframe) Time

Timing, timekeeping, time synchronization, more specifically accurate synchronization, is a key requirement for modern information technology systems.  This is especially true for industries involved in transaction processing such as the financial industry.  As such, the IBM Z sysplex needs highly accurate timing/timekeeping and synchronization technology to ensure data integrity, and to also provide the ability to reconstruct a database based upon logs. There have been 3 phases in the evolution of time synchronization on IBM Z.

You Do Not Need to Replace Your Legacy Enterprise Software

I recently read an interesting article on a vendor website – I got there after one of their spam emails caught my eye – “8 Signs You Need to Replace Your Legacy Enterprise Software” – I had to read that! I know a little bit about legacy software, and I was really curious about what they had to say. I have to admit that I was a little disappointed.

Porting an Enterprise App to System Z – My Experience Pt.4

Part 4 of 4: The Value and Future

In Part 1 The Basics, Part 2 The Good and Part 3 The Bad, I’ve explained I did a proof of concept port of an Enterprise Application from Amazon Web Services on x86 to Linux on System z in 2017. The good news was I got to the point I needed to, the bad news was it was more than difficult to get there. But why did I go there in the first place?

Digital Denial: Why You Can’t Trust the Application Economy

The NYSE and a major airline shut down and, in the case of the airline, shuts down twice is just over a month. Major retailers and a Federal employee databases get hacked. This seems like IT service levels from 1965 not 2015.

Does anyone still believe the application economy can actually work the way it should?

IBM z14 Model ZR1: A Smaller Mainframe for a Larger World

On April 10, 2018, IBM announced their latest mainframe offering, the IBM z14 Model ZR1. This announcement came hot on the heels of the original z14, which was delivered less than a year earlier in July 2017. So why the new model? And what does it mean to mainframe users out there?
