Infrastructure Automation Automating infrastructure increases efficiency, reliability, repeatability, and more. Managing servers through GUIs can be laborious, and it’s difficult to keep track of all the appropriate buttons to click for a correct deployment and configuration. Moving from a GUI (graphical user interface) to a CLI (command line interface) is a start, though you still…

State as a concept is broader than databases, and so to understand state in Kubernetes, and in particular the difference between StatefulSets and PersistentVolumes, let’s dive into state abstractly. State is the condition or…

Today we are going to talk about storage design with PKS. Before we can talk about what is supported and how it works, let’s make sure we understand why we need persistent storage. Datadog has given us statistics that in 2018, seven out of ten cloud-native applications needed persistent storage. So how can the application…

Disposability Kubernetes is designed to facilitate many cloud native principles; for example, disposability. Disposability means that workloads should be ephemeral where possible – easily replaced rather than migrated, fixed or upgraded directly. Disposability is often described as managing servers like “cattle not pets.” That means don’t groom long living servers, dialing them in manually, SSH’ing…

VMware PKS fully leverages vSphere clusters. Let’s take a look at the supported cluster design and implementation. When we look at vSphere clusters, the minimum amount of host is 2 and the maximum is 64, and those are the guidelines according to vSphere limits. You can have many clusters per vCenter server. There is not…
