Step-by-step guide to upgrading Tungsten Clustering and Replicator from version 6 (non-SSL) to version 8 (SSL-enabled). Learn how to enable SSL for MySQL, Tungsten Connectors, and REST APIs with minimal downtime and maximum data security.

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.

An analysis of the AWS outage and how cross-cloud continuity ensures uptime across cloud providers using solutions like Tungsten Cluster.

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.

Challenges of running MySQL on Kubernetes and how Operators ensure reliability through replication, failover, and observability.

Tungsten Dashboard v8.0.2 introduces major performance improvements, real-time cluster visibility, and enhanced usability with an intuitive Add/Edit Cluster workflow, namespace visibility, and configurable light/dark themes. The release also includes a redesigned installer with configuration reset, Docker Compose plugin support, and self-signed certificate generation. New tools like collect-diag.pl and getcert.pl --base64 simplify diagnostics and Kubernetes integration, while fixes improve coordinators and search performance.

Tungsten Cluster & Tungsten Replicator v8.0.1 focus on improving security, configuration management, and observability. The release introduces tpm INI upgrade and validation enhancements, dual MySQL SSL certificate for seamless certificate rotation, and new Prometheus metrics for deeper Replicator insights. It also delivers multiple CLI and stability fixes and adds certification for MariaDB 11.4, making upgrades and day-to-day operations safer and more transparent.

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.
