Package Management Perhaps the most common package manager in all of IT is Debian’s APT (Advanced Package Tool). It gives you an easy way to install applications rather than downloading, unzipping, and placing them manually (plus a few additional steps). Instead of all of that, you simply run “apt-get install [PACKAGE_NAME],” perhaps add some options…

When it comes to Security, VMware PKS has several levels and considerations. We can leverage the Microsegmentation of Microservices all the way to scanning an image in Harbor, and permit or deny a developer from downloading or pushing a particular image.  Let’s take a look at the different levels that PKS Security is working to help provision a trusted environment.  When we think…

VMware PKS fully leverages vSphere NSX-T. Let’s take a look at the supported NSX-T design and implementation. NSX-T licenses come with PKS, so there is no reason not to leverage the best in class network virtualization. First, let’s take a look at what is available by using open source networking, and what the advantages are…

State Many people associate state with databases, and that’s fair enough; databases are most certainly stateful and a prime use case. 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…

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. One such principle is “strict separation of config from code,” which is accomplished in Kubernetes through Secrets and ConfigMaps….
