This blog will discuss about different ways to encrypt your data using MariaDB Database Server. It covers encryption in-transit, at rest, and RDS.

Database Automation with Puppet: Deploying MySQL & MariaDB Galera Cluster

This post walks you through deployment of MySQL/MariaDB Galera Cluster using Puppet module. We’ll also look at how ClusterControl can be used to automate the management aspects of the environment once it’s set up.

Database Automation with Puppet: Deploying MySQL & MariaDB Replication

This post walks you through deployment of MySQL/MariaDB replication using Puppet module. We’ll also look at how ClusterControl can be used to automate the management aspects of the environment once it’s set up.

How to Automate Migration from Standalone MySQL to Galera Cluster using Ansible

Database migrations are painful, as they involve a lot of steps - from creation of the target infrastructure to migrating schema and data, and oh.. a lot of testing. Some of the steps can be automated though, you can rely on Ansible. This blog post presents a playbook that can be used to assist in the process of migrating to Galera Cluster.

How to Migrate WHMCS Database to MariaDB Galera Cluster

The WHMCS software suite relies on a MySQL database to store its data, so how do you make it highly available? This blog post shows how to migrate the existing WHMCS database from a standalone MySQL server (provided by the WHM/cPanel server itself) to a three-node MariaDB Galera Cluster to improve the database availability.

How to Execute and Manage MySQL Backups for Oracle DBA’s

Whether you’re planning to migrate from Oracle database to MySQL or run your new project with MySQL, you need to know how to do copies of your data. In this blog post, we will cover some of the most typical cases of the data backups with reference to Oracle backup methods.

How to Perform a Failback Operation for MySQL Replication Setup

In case of master failure in a MySQL Replication setup, the most updated slave can be promoted to new master and all slaves repointed to the new master. But once the failed master has been fixed, what is the best way to re-introduce it as master, so as to restore the original topology.

This blog post shows how to perform the MySQL master failback operation.

Monitoring & Ops Management of MySQL 8.0 with ClusterControl

MySQL 8.0 is a big step forward in terms of data consistency, developer features, performance and availability. MySQL 8.0 shortens the gap between proprietary databases and open source world, making the migration decision much easier to take.

But how can you manage it, along with other relational open source databases? In this blog post, we look at the challenges of operating a MySQL 8.0 database, and see how important tasks like monitoring, alerting, backups and failover can be handled in an automated way.

Database High Availability for Camunda BPM using MySQL or MariaDB Galera Cluster

This blog post covers how to deploy a highly available MySQL or MariaDB database cluster for Camunda BPM 7.10 Community Edition on Linux. Camunda supports major databases through JDBC drivers, namely Oracle, DB2, MySQL, MariaDB and PostgreSQL. We will show two different implementations for the database endpoint, one leveraging ProxySQL and the other using the standard JDBC driver.

Understanding the Effects of High Latency in High Availability MySQL and MariaDB Solutions

To insulate our database infrastructure from failures, we build redundant cluster systems. For instance, MySQL and MariaDB high availability can be implemented by master-slave as well as master-master replication solutions. There are a number of variables that affect our choice solution. In this blog, we will look into considerations around latency.
