D2iQ (formerly known as Mesosphere) announced the availability of two new products for the Kubernetes community. More on that announcement here. The first is Konvoy, a managed Kubernetes platform. Konvoy provides a standalone production-ready Kubernetes cluster with best-in-class components (CNCF projects) already integrated into for operation and lifecycle management. The solution enables developer agility and faster time to market for new Kubernetes deployments. The second announcement is Kommander. Kommander will enable better visibility and control across multiple Kubernetes clusters. Both ..read more

NuoDB is a container-native adaptive-scale distributed SQL database designed with distributed application deployment challenges in mind. The NuoDB database is ANSI SQL compliant and seen in a new category called “NewSQL.” If you are not familiar, what is different with NewSQL solutions is explained in a 2016 research paper here. Some of the solutions in this category are Amazon Aurora, Google Spanner, TiDB, CockroachDB, Altibase, Apache Ignite, GridGain, Clustrix, VoltDB, MemSQL, NuoDB, HarperDB, and Trafodion. NuoDB has a distributed obje ..read more

It’s been some time since I wrote about IBM Cloud Private 2.1, although I’ve been heavily using it in my lab. Improvements from version 1.2 to 2.1 were massive. We have also noticed the changes in the OpenEBS user community, according to our surveys usage of ICP increased dramatically. The Community Edition of the ICP 3.1 came out three weeks ago. CE container images were released with a slight delay of two weeks after the after the enterprise version came out. And I believe that it deserves an updated blog to talk about the steadily advancing developer experience (and my favorite new features ..read more

Run GitLab on a K8s-based private cloud After Microsoft announced the acquisition of GitHub, many developers raised concerns on social media about Microsoft’s history of unsuccessfully running the acquired businesses like Skype, Nokia’s handset business, Navision, and other 150 companies (you probably haven’t noticed) they have swallowed up over the years. Other than keeping the developer’s life-support plugged, one of the biggest concern is that MS will use its power on GitHub repositories to analyze trends among software development in order to launch competing products. Fears that GitH ..read more

Running stateful containers on Le Potato Why not! It’s fun and extremely efficient! I know many people (including me) used to run ownCloud on their desktop computers. I have finally decided to retire my old desktop computer and was looking ways to keep my ownCloud instance alive and maybe even improve it a bit. First, I ran ownCloud on GKE Kubernetes cluster and came to a conclusion quickly that it’s not what I needed: I am used to the speed of USB 3.0 for large uploads when needed. I wanted to keep the option of (40MB+/sec) using USB. Which means, if I choose a budget ARM SoC route, then th ..read more

What is OpenShift Origin? OpenShift Origin is the upstream community project used in all deployment models provided by Red Hat OpenShift such as OpenShift Online, OpenShift Dedicated, and OpenShift Container Platform. Red Hat OpenShift is an enterprise container application platform that is based on a core of Docker container packaging, Kubernetes container cluster management and the OpenShift Origin project itself. First, having more than one option sounds confusing, but they clearly differentiate from each other. Here is the summary of all available deployment options to start with ..read more

What is StackPointCloud Trusted Charts? StackPointCloud (SPC) introduced a concept of Trusted Charts, a list of validated Helm Charts provided by its partners to quickly spin up a solution in a Kubernetes cluster. Helm Charts helps you define, install, and upgrade even the most complex Kubernetes application. Previously, I wrote about few different ways of getting OpenEBS up and running on different cloud vendors. Using Helm Chart is one of the available options to deploy OpenEBS. OpenEBS Helm Charts were available since v.5.0 both on Github and as a packaged chart. Recently SPC included ..read more

Blogging is fun and it takes time. Leaving aside the research part, preparing all prerequisites takes a lot of time – also fun and educational. I have a few permanent clusters spread across cloud vendors and little more than a half rack of servers in my garage. Development VMs and Kubernetes clusters on AWS, a bare-metal VMware cluster mostly used for NFV testing and few old applications on Windows VMs, an IBM Cloud private cluster, an OpenStack cluster for a various break and fix experiments, a scale-out NAS and SAN providing storage for all servers in the garage. I started to think I sh ..read more

Apache Cassandra is a distributed key-value store intended to run in a data center and also across multiple data centers. Initially it was designed as Facebook as an infrastructure for their messaging platform. Later it is open sourced, and today it’s one of the most active Apache projects. If you are using eBay, Twitter, Spotify or Netflix you are consuming data provided by Cassandra. For example, Netflix uses Cassandra to keep track of your current place in a streaming video, as well as movie ratings, bookmarks and user history of 90+ million users. Amazing to see how much of this technology ..read more
