This is the second post where I look back at 2016 with some reflections on the most useful and interesting topics that I explored in the year that just passed. I really enjoyed writing the series on modernization, sig-nif-i-cance and the cloud economy. Modernization was a topic I knew about but never fully explored. It was timely to write about the cloud economy as it was a hot topic in 2016. The sig-nif-i-cance series was fun for me to indulge in and re-explore some of my favorite topics. Here is a quick recap.
For the modernization topic, I wrote seven related posts. I started with a post explaining the main ideas called What is Modernization?
Then I moved on to specific focus areas like mobility, data repository, application change, COBOL/VSAM, DB2/IMS database and finished with CICS and IMS Transaction Manager. As I was writing this series, I came up with the idea of internal modernization giving a label to the enormous human resources spend by IBM and others in the industry, to improve and redevelop software from the COBOL compiler to considerable subsystems like CICS, IMS and DB2. Many of the ideas in these posts fueled a couple of longer articles on modernization. The first of the series focused on revising existing mainframe applications to enable their full potential
The sig-nif-i-cance series consisted of nine posts. The group started with COBOL
and ended with IT disciplines.
I had a chance to write about other topics like virtualization, z/OS, JES, CICS and IMS, SMF, Workload Management and SMP/E. Some of these topics like CICS and IMS are familiar to many in IT and their significance is perhaps unquestioned. However, many in IT on mainframes don’t have exposure to components like SMF and SMP/E, so through these posts I hoped to give greater exposure to these important software components.
The Cloud Economy
Early in the year, I wrote a series of posts on new software economies. As part of this series, I explored cloud computing as a new software economy. The first in the series, new software economies
, introduced the main idea. Individual posts for the cloud economy included software and hardware; people, procedures and data; and hybrid computing. If you want to review the series, a good place to start is Another New Economy: Cloud.
Next week I’ll start a new series. My focus will be the skillset needed to be successful in IT with enterprise systems.
