Creating Clusters

Create clusters through the Webscale Control Panel

A cluster is a collection of servers that can be used to scale an application horizontally. It does this by adding or removing servers. Before you can configure a cluster, a provider blueprint must be created.

Add a provider

To add a cluster you will first create a provider blueprint. Log into your Webscale Control Panel, then click the settings gear on the upper right and choose Account Settings from the menu. From here click the Providers tab. Any providers you already have will be listed here, and you can select the cloud provider from the drop-down list. To add a new one, click the Add Provider button.

Add Provider Dialogue

Here, your choices will vary depending upon which provider you’re using. If you have questions about what options to choose here, please feel free to reach out to support.

Add a cluster

Once the provider is added, you can create the cluster. Click the Clusters tab, then click the Add Cluster button.

Once here, you will update the properties of the cluster:

  • Name of cluster
  • Minimum and maximum size of Servers allowed in this cluster.
  • Flavor/Size of Servers
  • Blueprint of Provider, which includes the following:
    • Provider (added above)
    • Region
    • Zone
    • AMI image
    • Instance type
    • Network Subnet
    • Security Group
  • Scale in/out conditions (use predefined conditions on which the cluster will scale in/out).
  • A bootstrap file, if you have one.

Associate the cluster to an application

Once you’ve added a cluster you can specify the cluster to be used for scaling in your application settings. To access these settings, log in to your Webscale Dashboard and click the 3 vertical dots on the upper right corner of the box for the application you wish to view and click Edit from the dropdown. From here, click Servers. Then, choose the existing cluster from the dropdown under Scaling Cluster.
