What is Auto-Clustering

What Is Auto-Clustering

Auto-Clustering helps create reliable, production-ready clusters directly from the topology wizard, reducing the time and manual effort normally required to configure multiple service instances.

For production workloads, using two or more service instances improves data availability, reliability, and the ability to handle increased load. A clustered service can continue operating when one instance fails and can distribute traffic or processing across several nodes.

Manual cluster configuration can be complex and time-consuming. The platform automates several popular clustering scenarios and exposes them as an on-demand option during environment creation or topology editing.

Why Use Auto-Clustering

Higher Availability Multiple instances allow the service to continue running when one node becomes unavailable.
Improved Load Handling Requests and workloads can be distributed across several service instances.
Faster Configuration Predefined automation removes much of the manual cluster setup work.
Production-Ready Topology The platform applies the required cluster structure and supporting configuration during deployment.

Enabling Auto-Clustering

1Select a supported stack

Open the topology wizard and choose one of the supported application server, database, or storage templates. The Auto-Clustering switch appears in the central part of the topology frame.

2Review the cluster description

Hover over the hint icon to see information about the selected stack’s clustering implementation. Use the Learn More link when a detailed explanation is required.

3Configure additional cluster options

After enabling Auto-Clustering, additional controls may appear. These options depend on the selected stack. For example, a MariaDB cluster can offer a replication scheme selector and an optional dedicated ProxySQL load balancer.
