Meet Galera Cluster at Percona Live Europe 2019 (Amsterdam)

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 …

Galera Cluster hiring for Quality Assurance Engineer

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 …

Running Galera Cluster on Microsoft Azure and comparing it to their hosted services (EMEA and USA webinar)

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.

Setting Up a Galera Cluster on Amazon AWS EC2

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.

Running Galera Cluster effectively on Amazon Web Services (AWS) and comparing it to RDS and Aurora (EMEA and USA webinar)

Do you want to run Galera Cluster in the cloud? Why not learn to setup a 3-node Galera Cluster using Amazon Web Services (AWS) Elastic Compute Cloud (EC2), and run it yourself (3-node because this is the minimum preferred size; you can have a 5, 7, or 9 node cluster too — not in the demo though!). In this webinar, we will cover the steps to do this, with a demonstration of how easy it is for you to do. We will also cover how you may want to load balance traffic to your Galera Cluster using a proxy like ProxySQL.

In addition, we will cover why you may want to run a 3-node (or more) Galera Cluster (multi-master synchronous clusters) instead of (or in addition to) using Amazon Relational Database Service (RDS) MySQL, which has the ability to have asynchronous replication (Read Replicas), and High Availability provided by DRBD (Multi-AZ). We will also cover where Galera Cluster differs from Amazon Aurora RDS for MySQL.

The key takeaway from that event would be Seppo Jaakola’s talk titled: Galera Cluster New Features. It covered the then upcoming MariaDB Server 10.4 release with Galera Cluster 4, went in-depth into how streaming replication works …
