EverData a leading data center and cloud solution provider in India has recently been writing quite a bit about Galera Cluster and it seems like we should highlight them. For one, they’ve talked about streaming replication in Galera Cluster 4, available in MariaDB Server 10.4. However, let us focus on their post: Galera Cluster vs Amazon RDS: A Comprehensive Review.

They compared MySQL with MHA, MySQL with Galera Cluster and also Amazon Web Services (AWS) Relational Database Service (RDS). Their evaluation criteria was to see how quickly there would be recovery after a crash, as well as performance while managing concurrent reads and writes.

In their tests, they found that time for …

We (Codership, the original and continued developers and experts of Galera Cluster) participated in Austin 2019, and so it would have seemed remiss if we did not also show up at the Percona Live Open Source Database Conference Europe 2019 (that was a mouthful!) happening in Amsterdam September 30 – October 2 2019. We have a booth in the expo hall at the Hilton Amsterdam Schipol Airport, so come drop by and say hello!

While we do not have any talks accepted in the main program, we do have a tutorial that involves using Galera Cluster and MariaDB Server on the first day at 9am by Colin Charles.  View the whole …

Do you think Quality Assurance (QA) is more than the simplistic view of bug hunting? Do you believe that QA is important to the entire software development lifecycle and want to focus on failure testing, process and performance control, as well as best practice adoption? Do you enjoy doing performance benchmarks and noticing regressions? Do you like to write about it, from internal reports to external blog posts?

Then why not take up a challenge at Codership, the makers of Galera Cluster, as we are looking for a Galera Cluster QA Engineer (job description at link).

We’re looking for someone who is able to work remotely, join a company meeting at least once per year, be comfortable with the use of Slack and email (asynchronous communication, for developing our virtually synchronous replication solution!), but most importantly enjoy testing the …

Do you want to run Galera Cluster in the Microsoft cloud? Why not learn to setup a 3-node Galera Cluster using Microsoft Azure Compute Virtual Machines, and run it yourself. In this webinar, we will cover the steps to do this, with a demonstration of how easy it is for you to do.

In addition, we will cover why you may want to run a 3-node (or more) Galera Cluster (active-active multi-master clusters) instead of (or in addition to) using Azure Database for MySQL or MariaDB. We will also cover cost comparisons. 

Join us and learn about storage options, backup & recovery, as well as monitoring & metrics options for the “roll your own Galera Cluster” in Azure.

Through Amazon Web Services (AWS), you can create virtual servers (i.e., instances). You can install database and Galera software on them. In this article, we’ll create three nodes, the minimum recommended for a healthy cluster, and configure them to use Galera Cluster.

Incidentally, there is a more detailed version of this article in the Tutorial section of our Library.

Assumptions & Preparation

We’re assuming you have an AWS account and know the basics of the EC2 (Elastic Compute Cloud) platform.

To access the nodes, you’ll need an encryption key. Create a new one specifically for Galera, using a tool such as ssh-keygen. Add that key to AWS, under Key Pairs.
