Creating a cluster

Provision a new Cassandra or DataStax Enterprise cluster locally or in the cloud using OpsCenter.

1. Click New Cluster.
2. Click Create Brand New Cluster.
   The Create Cluster dialog appears.
3. Click Cloud or Local.

   The Cloud and Local buttons appear only if OpsCenter is running in the cloud.

4. Complete the fields as appropriate.

   • If you select Local, the Local pane appears.

     
     
     
     
     

   • If you select Cloud, the Cloud pane appears. OpsCenter currently only supports the AWS EC2 cloud.
