A robust monitoring setup is essential for cluster health and viability - if your replicator goes offline and you do not know about it, then that Replica becomes effectively useless because it has stale data. This means keeping a close watch on the health of the MySQL / MariaDB / Percona Server database nodes from many perspectives, from ensuring sufficient disk space to testing that replication traffic is flowing.
Tungsten Clustering offers a graphical administration tool called the Tungsten Dashboard™ to help with your management burden. The GUI makes the deployment much easier to visualize and administer.

In this blog post, we talk about how to run applications across multiple clouds (i.e. AWS, Google Cloud, Microsoft Azure) using Tungsten Clustering. You want your business-critical applications to withstand node, datacenter, availability-zone or regional failures. For SaaS apps, you also want to bring data close to your application users for faster response times and a better user experience. With cross-cloud capability, Tungsten also helps avoid lock-in to any particular cloud provider.
This distributed topology, perfect for multi-region SaaS models, allows you to have all the benefits of high availability with centralized writes and local reads for all regions. Latency is limited only by the WAN link and the speed of the target node.
This blog post covers global MySQL / MariaDB / Percona Server clustering with Active/Active meshed replication, the architecture commonly used for globally-distributed SaaS companies.
What if I want the cluster to be less sensitive to network, especially WAN latency?
