In my first article of this series on Support in the 21st Century, I laid out my thoughts about the baseline expectations for the corporate support model and structure established at most companies. This is where I first brought up technology silos and presented the correlation between the number of technology silos and the size of the infrastructure.
I wrote a couple of articles many years back about building an agile and flexible enterprise using a set of models, principles, and design rules that address the need to maximize financial return, improve performance, minimize risk, and enhance business agility. I want to revisit the premise of that article and view it through the lens of DevOps.
In my last article, I laid out the baseline expectations for the support model and structure at most companies. In the past twenty years or so, these have been my observations and expectations any time I have started any new assignment in a new company. When starting a new position in a new company, there is a certain level of comfort, which comes from experience, in having at least a basic understanding of what to expect. There is always a technical learning curve that comes with anything new, but it makes the transition easier having a basic understanding of how things will be supported. That concept has served me well over the years. However, just as virtualization and cloud computing have changed the data center landscape, I think change in the support structure is well on its way. Now would be a good time to have a look at what works and what doesn’t.
Container technologies and developers work with applications. End users use applications. Yet, administrators think about the systems that make up the applications with tools that are not application-centric but rather system-, VM-, or container-focused. Because the tools are not focused on the application, the definition of the application is unknown by those who support the application. This is in serious need of changing. In fact, until this changes, a business cannot transform into the next generation of cloud-native applications. It just will not be ready. So, then, how do we get ready?
Containers are a hot topic these days. I have run a few workshops with clients, and one of the questions I get asked most frequently is “what are companies using containers for?” After answering this question a number of times, I thought I would share some common use cases with my readers.
