Blog

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.

Upgrades are a normal, expected part of all software lifecycles, and Tungsten is no exception. Keep your software up-to-date to ensure compatibility, supportability and the lowest risk possible to your operation.

It goes without saying that database security is top priority at Continuent; Tungsten Clustering customers in financial and healthcare organizations among others implement the strictest standards of data security, and so we have always kept it a mandate to not only support HIPPA and PII compliance, and maintain strict boundaries and protocols in design of our software solution and when providing support.

This blog post looks at the ins and outs of Amazon Aurora replication and how to best go about that; including all the details you need to replicate to and from Aurora with the Tungsten Replicator AMI.

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.

Disasters are waiting to happen. Like OVH data center fire on March 9, 2021. Do you have a solid MySQL Disaster Recovery (DR) plan in place to activate when the time inevitably comes?

If not, Continuent is happy to review your current MySQL HA/DR deployment and to recommend possible changes that might be recommended. Naturally, free of charge.

This post shares the links to three short demo videos, each an easy-to-follow walk-through of how to launch 3-node single, active/passive or active/active Tungsten MySQL clusters using AWS CloudFormation.

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.

Customers often ask where they should install their MySQL, MariaDB, or Percona MySQL database proxies for high availability clusters, and how many. What is optimal for you may not be the right configuration for everyone. However there are some best practices we’ll discuss in this basic blog about deploying MySQL database proxies.

The new role of recovery (RPO and RTO) in a continuous, highly available MySQL environment?

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.
