Kubernetes with Multiple CPU Architectures 2 of 2 – Node and Workload

For server CPU, the most common architectures today are amd64 (aka x86_64) and arm64. Although AMD developed the former first, Intel names it as x86_64 (or x64 for short). In terms of compatibility, they are the same. In general, arm64 architecture consumes less power and therefore mobile systems first favour it. Its power efficiency now … Read moreKubernetes with Multiple CPU Architectures 2 of 2 – Node and Workload

Kubernetes with Multiple CPU Architectures 1 of 2 – Container Image

While working on a multi-arch Kubernetes cluster, I came across quite a few issues with image logistics and decided to put these issues in a separate post here. The goal is to supply images with multi-arch support in a standard way. Therefore it is not advisable to rely only on arbitrary image tags to distinguish … Read moreKubernetes with Multiple CPU Architectures 1 of 2 – Container Image

Kubernetes Storage on Azure 3 of 3 – Ceph by Rook

In the last two posts, I covered the native storage options on Azure Kubernetes Service, as well as Portworx as an example of a proprietary Software Defined Storage (SDS) solution. There are also a number of open-source alternative SDS solutions. Ceph has nearly a decade of history from prior to containerization, and is the most … Read moreKubernetes Storage on Azure 3 of 3 – Ceph by Rook

Kubernetes Storage on Azure 2 of 3 – Portworx

In the previous post, we have discussed built-in storage classes on Azure Kubernetes. Further to that, we will examine some third-party software defined storage (SDS) options that are compatible with Azure Kubernetes Service in this post. Then we take Portworx on Azure as an example. Although, these options are specific to Azure, most of the … Read moreKubernetes Storage on Azure 2 of 3 – Portworx

Intro to Ceph storage

Ceph is a unified, distributed storage system designed for excellent performance, reliability and scalability. In this post, I will introduce Ceph and explain how it stands out from traditional enterprise storage technology. Software defined storage In the realm of enterprise storage, I discussed PowerScale (Isilon) from Dell EMC, and touched on ONTAP by NetApp as … Read moreIntro to Ceph storage
