Manage and Automate Galera Cluster – Why ClusterControl
Galera Cluster by Codership is a synchronous multi-master replication technology which can be utilized to build highly available MySQL or MariaDB clusters.
It has been downloaded over one million times since last year, establishing itself as one of the most popular high availability and scalability technologies for MySQL, MariaDB and Percona Server with database users worldwide.
And while Galera Cluster is easy enough to deploy, it is complex to operate. To properly automate and manage it does require a sound understanding of how it works and how it behaves in production. For instance, once it’s deployed, how does it behave under a real-life workload, scale, and during long term operations?
This is where monitoring performance and optimizing it, understanding anomalies, recovering from failures, managing schema and configuration changes and pushing them in production, version upgrades and performing backups come into play.
There are a number of things you’d want to have thought through and be in control of before going in production with Galera Cluster for MySQL or MariaDB:
- Hardware and network requirements
- OS tuning
- Sane configuration settings for the database
- Production-grade deployment
- Monitoring and alerting
- Query performance
- Anomaly detection and troubleshooting
- Recovering from failures
- Schema changes
- Backup strategies and disaster recovery
- Disaster recovery
- Reporting and analytics
- Capacity planning
And the list goes on …
We saw great potential in Galera Cluster early on, and started building a deployment and management product for it even before the first 1.0 version was released. We are happy to see that the technology has delivered on its promises – high availability of MySQL with good write scalability. Over the years, we have been able to build out comprehensive management procedures in ClusterControl and battle-test these across thousands of installations.
Not everyone has the knowledge, skills, time or resources to manage a high availability database. It is hard enough to find a production DBA, or a DevOps person with strong database knowledge. So imagine that most of the relevant steps in that process could be automated and managed from one central system?
This is where ClusterControl comes in.ClusterControl is our all-inclusive database management system that lets you easily deploy, monitor, manage and scale highly available open source databases on-premise or in the cloud.
