This article explores some of the leading MySQL — also including MySQL variants MariaDB and Percona Server — high availability (HA) and disaster recovery (DR) solutions – in alphabetical order, including AWS Aurora, Continuent Tungsten, DIY MySQL clusters, Galera Cluster, and MySQL InnoDB Cluster.

Beyond uptime lies the calm harbor of long-term administration for your MySQL high-availability solution. But navigating upgrade waves and vendor lock-in can be tricky. Let's chart a smooth course through these challenges and ensure your data sails serenely.

Explore the benefits of migrating from Galera Cluster to Tungsten Cluster for MySQL database infrastructure. Learn how Tungsten leverages asynchronous replication for robust performance, overcoming challenges faced by synchronous replication. Discover the ideal architecture for Geo-Scale MySQL clustering and how Tungsten Cluster simplifies deployment with CLI and GUI management tools. Gain insights into achieving high availability, Active/Passive, or Active/Active clusters.

Explore the benefits of moving from Galera Cluster to Tungsten Cluster in our blog series. Learn how Tungsten's asynchronous replication enhances application performance compared to Galera's synchronous replication. Discover the advantages of network tolerance, performance optimization, and scalability. Follow our series for insights into deploying database clusters at geo-scale with Tungsten Cluster.

VMware chose to migrate key MySQL database from Galera (MariaDB Cluster) to Tungsten. In this blog we will look at the key reasons for why VMware ultimately decided that Tungsten Cluster would better fit their multi-site MySQL clusters.

In this blog, we discuss Galera Cluster and synchronous versus asynchronous replication. We also discuss some of the differences between Galera Cluster and Tungsten Cluster rooted in this difference in foundation. And how Tungsten has served a critical niche - mission-critical, geo-distributed, highly-performant MySQL applications - for a long time.

Instead of contributing back to the original project, and in that way benefitting the project as a whole, Percona takes over smaller open-source projects (such as Galera) and larger open source projects (MySQL, MongoDB), then adds some small enhancements (especially when compared to the work done by the original developers), slaps its own name on it and proceeds to make some negative comments against those who have done the hardest work.

This blog is about open source MySQL clustering software, specifically Codership’s Galera Cluster and Percona’s fork of that, XtraDB Cluster. If you are considering using Galera, please use the original version, or please use the version by MariaDB, which is actively supporting the Galera team.

Migrating from Galera to Tungsten Clustering is easy with the tools provided by Tungsten Clustering. Because replication happens in the background, applications can stay online with a quick cutover to Tungsten Clustering when ready.

A telco company recently came to us looking for an improvement to their Galera deployment. Their two main complaints were the unplanned downtime forced by Galera Cluster [aka MariaDB Cluster or Percona XtraDB Cluster], and the lack of reliable geo-scale deployment. 

Continuent showed them how our solution, Tungsten Clustering, provides maximum MySQL uptime and is built for geo-scale (active/passive and active/active) MySQL deployments.

This is the second blog in our ‘High Noon’ comparison series in which we look at the main solutions for MySQL high availability, disaster recovery and geographic distribution. Here we focus on highly available, geo-scale, multi-region MySQL for mission-critical sites and apps with Codership’s Galera and its variants (MariaDB Galera and Percona XtraDB Cluster) as compared to MySQL clusters with Continuent Tungsten, the only complete, fully-integrated solution for highly-available MySQL clustering solution - for any version of MySQL, MariaDB, and Percona Server - on-premises, in the cloud, hybrid-cloud or multi-cloud.

This blog discusses Asynchronous versus Synchronous MySQL replication for MySQL clustering. Synchronous replication is viewed as the ‘holy grail’ of clustering. But unfortunately, when something is too good to be true, it often is. Before the Tungsten cluster solution Continuent built two synchronous replication cluster solutions (m/cluster, uni/cluster), but we abandoned those for good reasons.
