MySQL High Availability (HA) & Disaster Recovery (DR)

This is the third post in a short series about Tungsten Clustering topologies. In this post we will highlight the key differences between Composite Active/Passive, Composite Active/Active (CAA), and the newly available Dynamic Active/Active topology. In short, DAA blends the simplicity of CAP with the automated continuous operations of CAA.

You’ve seen the recent news about AWS outages; enterprises have to think about where their physical AWS data centers are and treat them as a single point of failure. As such, enterprises running business-critical and mission-critical applications are accounting for geography of public cloud resources in their business-continuity plans. Learn about a solution for continuous operations for your MySQL database that’s a step above traditional MySQL Disaster Recovery (DR).

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.

This blog takes a look at three stacks: networking, LAMP, and the modern MySQL database clustering stack. The networking stack is a foundational element of geo-distributed MySQL database services. LAMP is a common software solution stack used by web and other client-server applications. The modern database clustering stack enables multi-site, multi-region and globally distributed MySQL database systems for continuous operations, which Tungsten Clustering provides in a complete, fully-integrated and tested package.

“How can I simulate a failure of the Active half of an Active/Passive Cluster to test the Failover to the Passive half?”

In this blog post we explore the best practices for simulating a failure of the Active cluster in an Active/Passive Composite Cluster.

As we are all being pushed to the limit to meet unprecedented demands online, the pandemic shined a light on many new frontiers and achievements in technology. This blog is about continuous MySQL database operations when you have a global user base, particularly the VMworld 2021 Global Multi-Cloud conference.

MySQL High Availability (HA) is typically what architects and technologists look for in building business-critical and mission-critical applications, and they aspire to measure MySQL uptime in 4 or preferably more “nines.” This blog explores the modern world of continuous MySQL operations - cross-region, global, hybrid-cloud, and multi-cloud - and why you might need a different approach.

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.

On August 20th, 2020 we released v6.1.6 of our Tungsten Clustering and Tungsten Replicator products. On August 17th, 2021, we released v6.1.14. In this blog we take a look back over the last 12 months and highlight some of our key updates and fixes.

Doing a search with InnoDB Cluster with DR (Disaster Recovery) yields lots of results, but does it actually work in the enterprise?

For multi-site, multi-region, or geo-distributed MySQL or MariaDB clusters, Saas, Fintech and other organizations with business-critical MySQL databases typically require what’s called a managed “composite” cluster, or “cluster-of-clusters.” This blog is about active/active and active/passive composite clusters for multi-site MySQL and MariaDB database systems.
