Secrets and ConfigMaps

Overview Twelve-Factor Apps are apps that follow modern cloud native principles. Kubernetes is designed for such modern cloud native app development, and as such, many of Kubernetes features are intended to enable adherence to these principles.

App Refactoring and Considerations

When we say “app refactoring,” we are referring to the process of rewriting parts, or the entirety of, a software application without changing the app’s functionality.

What is Cloud Computing?

The problem with the term Cloud, in its popular usage in IT, is that it’s intended to obfuscate complexity to help a varied audience grapple with fundamental shifts in the industry. It’s a marketing term leveraged to sell products, rather than a technical classification described by the IEEE. Real clouds are amorphous and ethereal, and those attributes intentionally drive the metaphors inherent ambiguity. The fundamental point is that something provided to you by the Cloud is flexible and easy, in some way managed for you, and at least initially, hosted by the provider rather than in your own datacenter.

The mission of most medical institutions is to provide the best possible medical care to their patients while balancing costs. The goal of their IT departments is to empower this mission by deploying technologies that improve health care, reduce cost or both. For the data center teams, the best way to achieve this is by providing an infrastructure the reduces the friction of application owners to consume data center resources.

Network Definitions

“It is going to be ok…”. That’s what I usually tell Data Center Network folks when we talk about the future of Data Center networking. And just before they can finish the sigh of relief, I follow it up with “…if you are open to learning the new ways of doing things”. One thing we…
