Trevor Perry on Slide Decks and IT Strategy
January 1, 2018
Paul Tuohy: Hi everybody and welcome to the first iTalk with Tuohy of 2018. To kick off the year, I think no better person to maybe look back at 2017 with and to kick off the new year is my friend, my colleague, my fellow IBM Champion and general AS/400 evangelist, Trevor Perry. [Laughs] I […]
ArticlesManaging Emerging Technologies
December 18, 2017
In this post, I finish up my focus on the management theme from the previous four weeks of posts, with a concentration on the management of emerging technologies like robots and artificial intelligence (AI). There’s been much written about jobs being lost to new technologies like computerized algorithms (at this time) and autonomous vehicles (in […]
ArticlesA Focus on Cloud Management
December 11, 2017
In this post, I keep my focus on the management theme from the previous three weeks of posts with concentration on cloud. What is different with cloud as compared to system, network and application management? Don’t cloud services require system and network management? Don’t cloud services run an application so isn’t application management useful? Time […]
ArticlesA Comprehensive Approach to Application Management
December 4, 2017
In this post, I explore the discipline of application management, which is an IT management process with tools focused on the availability, performance and manageability of applications. Applications that have files, databases and other resources distributed over multiple OS images can be a challenge to manage. When suddenly some part of the application isn’t working, […]
ArticlesAge of Networks and Network Management
November 27, 2017
In this post, I explore the current state of network management, a powerfully mature discipline that emerged after going through many changes as networking evolved to its present state. Network management is still growing and evolving. That’s because network environments are still developing in sophistication, built-in support and changing device implementations like virtualized firewalls, switches […]
Comprehensive Systems Management
November 20, 2017
In this post, I explore systems management as a comprehensive discipline: What is it, how has it changed and what are the latest innovations to emerge. Systems management has developed into a mature and vibrant network of activities that are key to keeping systems available and useful. Let’s consider it as a model with categories […]
ArticlesIT Management Activities and Their Context
November 13, 2017
This is the first in a series about IT management. You might think of this as system, network, application and cloud management, but definitions and practices are changing and expanding. Or, you might think of this as IT Service management. That’s certainly part of it as well. IT service management creates context so it is […]
ArticlesDesign and Develop Large-Scale System Software
November 6, 2017
This is the sixth and final post in a series about things they never taught me in school. Over the years, I have taken many different computer classes in schools, through IT companies and by self-study, but nothing prepared me for the rigor of leading a team in the design and development of a large-scale […]
ArticlesHow to Create an IT Offering
October 23, 2017
This is the fourth post in a series about things they never taught me in school. Attending classes, I never learned how to create an IT offering. In fact, I never heard of an IT offering until I was 20 years into my IT career. At that time, elements like professional or support services were […]
ArticlesHow to Automate an Entire Software System
October 16, 2017
I studied to be a computer application developer. My interests were halfway between business and computers, so developing applications were a pretty good fit. Besides, I didn’t know anything about the system side of things—OSes, middleware software, job entry subsystems and system software installation—basically the tasks and concerns of the system programmers. After five years […]
