Practical guide to using Ansible safely with Tungsten Clustering, including outage analysis, maintenance mode usage, rolling database operations, and automation guardrails to prevent cascading failures in production MySQL clusters.

Comprehensive guide to implementing a real-world multi-region MySQL SaaS deployment with Tungsten Cluster, covering architecture design, automation, monitoring, and operational best practices.

Learn how to rotate MySQL SSL/TLS certificates with zero downtime using Tungsten Clustering 7.2.0/8.0.1 and the tpm cert tool, including generating certs, dual-alias rollout, safe node-by-node restarts, SELinux fixes, and cleanup to retire old aliases without interrupting production.

A deep dive into operational excellence and monitoring strategies for multi-region MySQL in SaaS environments — including deployment automation, observability, compliance, and recovery best practices.

An in-depth guide to multi-region MySQL for SaaS, covering design principles, challenges, and proven architecture patterns for global scale.

Learn why Kubernetes alone isn’t enough for running stateful databases and how Operators solve challenges like failover, scaling, backups, and upgrades. Discover how Tungsten Operator brings proven MySQL clustering, replication, and enterprise-grade HA/DR into Kubernetes.

For organizations running mission-critical MySQL clusters, even brief service interruptions can translate to significant losses. Modern MySQL environments face unprecedented complexity through geographic distribution, diverse workload patterns, and stringent availability requirements. Traditional monitoring approaches cannot address these challenges effectively, requiring comprehensive strategies that prevent issues before they impact operations.

Learn how to implement advanced MySQL health checks for HAProxy using systemd socket-based activation. Execute custom SQL queries for deeper database verification before routing traffic, replacing shallow TCP probes with intelligent failover decisions.

After two decades of helping enterprises achieve continuous MySQL operations, we've probably seen it all. The midnight calls about failed failovers. The "highly available" systems that went down for hours during a simple maintenance window. The multi-million-dollar applications that were brought to their knees by a single database node failure.

Learn how to use HAProxy with a Tungsten Connector farm to build a high-availability MySQL proxy layer. Explore deployment architectures, load balancing strategies, and HAProxy configuration examples.

Learn how to optimize MySQL replication performance in Tungsten Cluster by tuning the Applier settings. Improve replication speed, minimize commit overhead, and balance data availability with advanced tuning techniques.

Managing Tungsten Cluster configurations can be challenging, especially when dealing with powerful, yet complex tungsten.ini files. To simplify the process, the new tpm ini command provides an easy way to create, validate, and manage configuration files, helping database administrators streamline their workflow. This new command is available as part of our upcoming V8 software release.
