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 …

Codership is pleased to announce a new Generally Available (GA) release of Galera Cluster for MySQL 5.6 and 5.7, consisting of MySQL-wsrep 5.6.45-25.27 and 5.7.27-25.19 with a new Galera Replication library 3.28 (release notes, download) implementing wsrep API version 25. This release incorporates all changes into MySQL 5.6.45 (release notes, download) and MySQL 5.7.27 (release notes, …

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.

The MySQL Server High Availability landscape provides with a slew of tools to help you ensure that your databases keep humming. Such tools are Galera Cluster, however, it is worth looking at semi-synchronous replication with failover tools, and also the usual leader-follower asynchronous replication. Today more workloads are moving to the cloud, and what failover options do you get with Amazon RDS for MySQL or even Aurora? What about the newfangled group replication and InnoDB Cluster? And let us not forget that Galera Cluster has spawned branches too!

Join Codership, the developers and experts of Galera Cluster,  as we discuss where Galera Cluster fits in and how to get best out of it.

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.

Are you looking to get started with the world’s most popular open-source database, and wondering how you should setup your MySQL hosting? So many default to Amazon RDS, when MySQL performs exceptionally well on Azure Cloud. While Microsoft Azure does offer a managed solution, Azure Database, the solution has some major limitations you should know about before migrating your MySQL deployments. In this post, we outline the best way to host MySQL on Azure, including managed solutions, instance types, high availability replication, backup, and disk types to use to optimize your cloud database performance.

It is July now, and summer is upon us. The team at Codership are busy making Galera Cluster 4 for MySQL, and we are just hot of the heels of celebrating the launch of Galera Cluster 4 with MariaDB Server 10.4. 

At the end of May, Galera Cluster had a booth and several talks at Percona Live Austin. This was the first time the event happened there, and we thoroughly enjoyed it. 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 …
