A license for Bright Cluster Manager has two attributes that are important in this context:
- Pre-paid nodes:
- Max Pay-per-use nodes
The pre-paid node count is the number of nodes that may be started without incurring any additional charges. For Bright licensing it is irrelevant whether nodes are on-premise or off-premise (i.e. in a cloud). A license with a pre-paid node count of 100, will allow a user to start e.g. 80 nodes on-premise and 20 nodes in the cloud.
It is possible to add nodes to a cluster in excess of the pre-paid node count and pay for them by the node hour. To do this, the product key of the cluster must be associated with a Customer Portal account. In addition, the cluster must be able to reach burst.brightcomputing.com on TCP port 443. The value of the max pay-per-use node attribute in the license determines the number of nodes that may be started using pay-per-use pricing.
For pay-per-use pricing, Bright again does not distinguish between on-premise and off-premise nodes. For example, on a license with pre-paid node count set to 100, it is possible to start 150 physical on-premise nodes. In this example 50 nodes will be charged for by the hour.
Details on pay-per-use pricing can be found in the Customer Portal ('Prices' under Burst in the menu).
For Cluster-on-demand clusters (i.e. clusters that are started entirely in the cloud) that are created using the Customer Portal, users have the choice of using pay-per-use pricing or pre-paid pricing, or a combination of both. To use pay-per-use pricing, select 'New Product Key' in the form. To use pre-paid pricing (for at least part of the cluster), purchase a product key by contacting sales, and fill it into the form when creating a cluster on demand cluster.
