VMware held their SpringOne conference this week for developers and made a few announcements of note. If you can navigate the word salad , you’ll see that they’ve canceled their “Cloud Foundry on Kubernetes” program, effectively putting PCF on a dead-end path. Now maybe a good time to look at Kf . With Kf, you can migrate your Cloud Foundry applications to Google Kubernetes Engine or Anthos without changing your developer workflows. 1/ VMware Springone conference is currently underway where for the first time they have authoritatively sunset Cloud Foundry. See excerpt below from Tanzu Blog Nonetheless, after hundreds of discussions with our beta customers, we determined that the Tanzu Application Service for Kubernetes approach wouldn’t allow us to leverage and expose the key declarative primitives that make Kubernetes and its ecosystem so powerful. We also didn’t believe it would meet our standards for scalability, speed, security, and stability, nor would it deliver the kind of dev

CIO Guide To Large Application Modernization - Where The Wild Things Are!

July 06, 2021

App Modernization is a spectrum - ranging from VM lift'n shift to a full on rewrite. with replatforming to containers and refactoring somewhere in between. Consulting companies are minting millions billions of milking app transformation and digital transformation for all it worth. True app modernization begins from a position of pain and opportunity - Loss due the lack of new features or a feature velocity slow down due to technical debt or frequent change failures. When a confluence of business pain and paradigm shift in IT occurs such as cloud native, microservices and Kubernetes - large scale complex app modernization is funded (by LOB and IT). So the first thing we need to be super clear on - WHY are we decomposing the large monolithic application. What value do we expect to get from this endeavor quantified in business metrics that we can explain to the Board or the C-suite. The plan for monolith decomposition needs to include clear milestones and MVPs along the way

An Ode To The Pivotal Dojo

January 13, 2021

First it is ironic that I am writing this post about Pivotal my old employer as a Googler . So please remember that these thoughts are my personal opinion only and NOT Google's. Recently I got to legitimately reminisce about my early years at Pivotal. Dojo A dōjō ( 道場 , Japanese pronunciation: [doꜜː(d)ʑoː] [note 1] ) is a hall or place for immersive learning or meditation. This is traditionally in the field of martial arts, but has been seen increasingly in other fields, such as meditation and software development. The term literally means "place of the Way " in Japanese. From my perspectives here are the 5 key tenets of the DOJO methodology. Immersive Pair Programming- we used to call this - I do, We do , you do. The intent here is to teach them how to fish and not merely assist them or do it for them. Pair programming resulted in both enablement and delivery. Communication, feedback and quick decisions. Run the team like a product team. There are typicall
