Introduction What if you need quickly to launch virtual machine instances running Ubuntu for development and testing purposes. Multipass from Canonical can be the right tool for this. You can even customize the instances during launch by using Cloud-init in order to simulate a small cloud deployment from your laptop or desktop. So, in this short blog post, I will talk about this tool and demonstrate how easy it is to use it.
In this short blog post, I will discuss about SUSE Rancher 2.5, the latest version. In this release, the rancher-monitoring has been introduced. With this cool feature, you can quickly deploy open-source monitoring as Promotheus and Grafana for your kubernetes clusters
What if you need absolute control over maintenance and package deployment or if you need to keep them up to date or if you need to automate the software management and the system provisioning with a high level of security, SUSE Manager is the right tool you need. In this blog post I will describe how to install the latest version of SUSE Manager 4.1.
What if you could clone a PostgreSQL database instantly without affecting the original source database, without impacting performance, without any external tool but using your linux Btrfs storage layer. This is what I will demonstrate in the following blogpost.
In my previous blog, I talked about how to install the latest MariaDB Community Server 10.5.5 on CentOS 8 but now I will talk about the latest version of MariaDB ColumnStore 1.5 which is not anymore a separate fork of MariaDB but rather a pluggable storage engine. This allows to move easily data from InnoDB to ColumnStore and it is also the first version to be released as a plugin for the community Server.
One really good feature from SUSE Linux Enterprise (SLE) is that it allows you to upgrade from your running system to a new service pack online. Let’s say from SLE 12 SP3 to SLE 12 SP4. No new installation is needed. All existing data are kept intact. In the following blog post, I will show you how easy it is.
Mistakes or accidental data deletions can sometimes happen on a productive MariaDB Galera Cluster and this can be disastrous. There are so many cases I have heard by customers and hereafter are some of the most common: – dropping one column of a table – dropping one table – updating a big table without a where clause What if it was possible to restore online a subset of data without downtime?
Registration Last Friday (17/01/20) I had the opportunity to go to Geneva at CERN to attend a PostgreSQL meetup. I’m really happy to write a blog about for a lot of reasons. First of all, it was about PostgreSQL (essential these days), also for the contributors as Oleg Bartunov and finally because of the organizers: Franck Pachot (old & soon new colleague by dbi-services) & Laeticia Avrot I met at the SOUG Day in Lausane.
