MySQL Replication for High Availability - New Whitepaper

This whitepaper covers information about MySQL Replication, with information about the latest features introduced in 5.6, 5.7 and 8.0. There is also a more hands-on, practical section on how to quickly deploy and manage a replication setup using ClusterControl.

Deploying Secure Multicloud MySQL Replication on AWS and GCP with VPN

MySQL Replication is still favored by some organization as it's simple to implement and run. However, in a multi-cloud setup like Google Cloud Platform <–> Amazon Web Services, things can get tedious without proper cluster management, monitoring and observability tools. This blog showcases how to create a secure implementation of cloud <–> cloud replication and how ClusterControl can be used to resolve these impediments.

ClusterControl Tips & Tricks - Dealing with MySQL Long Running Queries

Long running queries are pretty much inevitable in MySQL or MariaDB, and unfortunately, they can lead to disastrous results. But why do queries take long time to execute? How do you deal with them?

This blog post shows how you can use ClusterControl to easily detect them, especially in environments with many database instances.

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.

How to Run and Configure ProxySQL 2.0 for MySQL Galera Cluster on Docker

ProxySQL 2.0 has become GA and it comes with new exciting features such as GTID consistent reads, frontend SSL, Galera and MySQL Group Replication native support. This blog post shows how to run the new ProxySQL 2.x for Galera Cluster on Docker container, which is quite a bit different as compared to ProxySQL 1.x.

An Introduction to Database High Availability for MySQL & MariaDB

These days high availability is a must for any serious deployment. Long gone are days when you could schedule a downtime of your database for several hours to perform a maintenance. Making a database environment highly available is one of the highest priorities nowadays alongside data integrity. For a database, which is often considered the single source of truth, compromised data integrity can have catastrophic consequences.

HA for MySQL and MariaDB - Comparing Master-Master Replication to Galera Cluster

Replication and Galera Cluster are both widely used to implement high availability for MySQL/MariaDB, but when should you pick one over the other? What are the limitations of each solution, and what are the trade offs?
In this blog post, we will look at the differences in terms of data consistency, conflict resolution, failover, node provisioning and robustness.
