MongoDB Cluster

Use this guide when users need MongoDB with a replica-based topology for higher availability and better production resilience.

Recommended deployment mode: Database Cluster. This is the right fit for production MongoDB workloads that cannot rely on one standalone node.

Provisioning Flow

Start the Database Workflow

Open the database deployment flow and select MongoDB.

Configure Cluster Topology

Choose the clustered option, set replica count, storage size per node, credentials, and environment.

Deploy and Validate

Provision the cluster, then verify replica health, internal endpoint connectivity, and storage attachment for each node.

Common User Mistakes

  • Application clients connect to a single pod instead of the intended cluster endpoint
  • Replicas are provisioned without enough storage planning
  • Users assume clustering replaces backup and restore planning
