VMworld last week continued 2020’s atypical tech world tradition of offering all its sessions virtually. That format definitely makes the audience transition from session room to session room much quicker and easier. But for those of us tracking our physical activity we earn many, many fewer steps! 

This year’s conference offered the usual, very broad selection of sessions. They addressed all the new offerings and features and trends in VMware’s huge portfolio of products and offerings. In my opinion, as an application solution techie geek, the fundamental transition of vSphere to an orchestrated container platform based on Kubernetes (demystified in App Modernization ) was far and away the most interesting track of the conference. The architect in me votes hands-down that Paul Czarkowski’s session, Cloud Native Operations on Kubernetes, was the best presentation of the conference. No question it’s worth an hour of your time!

32-bit Apps in a 64-bit Docker Container

I started my career in December of 1989 at a company named Planning Research Corporation which contracted a considerable amount of work with the Department of Defense. I spent one year working in Fortran 77. The next 6 years were far more interesting to me as I dove into the world of ANSI C programming using the Kernighan & Ritchie bible. I still have my book on a shelf.

Our systems ran on 3 different Unix operating systems. We managed Makefiles that targeted SunOS, DEC Ultrix, and IBM AIX platforms. At times this was quite challenging. However, everything in this environment was 32 bit architecture; but what did that matter to me at the time? 64 bit processors didn’t come along for many more years.

Docker Clustering Approaches

Leave a Comment / Architecture, Docker, Swarm / / , , , , ,

Most enterprises have a structured release management process that allows phased deployment between multiple environments including development, test, model (stage or acceptance), and production.  https://en.wikipedia.org/wiki/Deployment_environment.

With Docker Enterprise Swarm you can generally setup these environments in one of the following ways: Single Cluster, Multi-Env Cluster, Geo-Single Clusters, and Geo-Multi-Env Cluster.  I will explain these different approaches and help you determine when each approach might be useful in your enterprise.  Of course, there is a myriad of variations on each of these that you could employ to suit your own needs.
