AWS may reboot your Aurora database. What is the impact?

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.

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.

Galera Cluster provides high availability and scalability for MySQL. While this provides high availability in a local region or site, it does not provide any provisions for disaster recovery (DR) or any multi-site deployment in general, so let’s explore how we could extend the functionality of Galera Cluster to deploy at geo-scale.

Oracle MySQL InnoDB Cluster provides high availability and scalability for MySQL. An InnoDB Cluster consists of 3 or more MySQL instances in a local network with group replication enabled, MySQL Shell which is used for management of the cluster, and optionally MySQL Router to provide basic routing from applications to the cluster. While this provides high availability in a local region or site, it does not provide any provisions for disaster recovery (DR) or any multi-site deployment in general, so let’s explore how we could extend the functionality of InnoDB Cluster to deploy at geo-scale.

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.

This is the next blog in our competitor 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 ClusterControl as compared to MySQL clusters with Continuent Tungsten, the only complete, fully-integrated clustering solution for MySQL - on-premises, in the cloud, hybrid-cloud or multi-cloud.

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.

For the sixth in the Competitor Comparison series in which we look at the main solutions for MySQL high availability, disaster recovery and geographic distribution, I got a chance to interview Matt Lang, Customer Success Director, Americas at Continuent. We focused on highly available, geo-scale, multi-region MySQL for mission-critical sites and apps with Do-it-Yourself (DIY) solutions as compared to MySQL clustering with Continuent Tungsten, the only complete, fully-integrated clustering solution for MySQL - on-premises, in the cloud, hybrid-cloud or multi-cloud.
