  • Recapping Blogs on Areas of Innovation, Teams and Development Methods/Architectural Styles

    This is the second of two recollections looking back at posts from IT Trendz published in 2017. In this post, I explore three more of the 12 themes and variations that I explored and discussed last year. My focus in this post is areas of innovation (the chicken or the egg question), team structures (like you, I have experienced and observed a variety of organizational constructs) and ways to develop applications (including a discussion of architectural styles).

    Recapping Blogs on Skills, Trends and Teachings

    This is the first of two recollections looking back at posts from IT Trendz published in 2017. If you read IT Trendz, you have probably noticed that the posts that appear week-to-week are usually part of a theme or linked to a main idea. An individual post explores some aspect of the subject. Usually, I have three or four posts on the idea. In this post, I want to explore three of the 12 themes (and some of the 49 variations) that I explored and discussed last year.

    A 2017 Writing Recap: A Productive and Interesting Year

    In this post, I begin a brief look back at some of the topics I explored in 2017. Since you’re reading this post, you’re aware of IT Trendz (and hopefully a regular reader), but here are some articles that you may have missed that appeared in IBM Systems Magazine and in Destination z.

    Managing Emerging Technologies

    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 the future). Now that these technologies are maturing rapidly, what management challenges are inherent with them?

    A Focus on Cloud Management

    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?

    A Comprehensive Approach to Application Management

    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, what’s wrong?

    Age of Networks and Network Management

    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 and routers.

    Comprehensive Systems Management

    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 and activities.

    IT Management Activities and Their Context

    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 useful to include a framework like the ITIL because management categories like application management map to it. ITIL isn’t the only framework that gives context.

    Design and Develop Large-Scale System Software

    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 system software product that was expected to be used by many hundreds of customers. Let me explain.
