Billing Modes

Pay-per-use
In pay-per-use mode, you are billed for a full hour even though you use CSS for less than 1 hour. You can enable or disable CSS as you like.

Changing the Billing Mode

CSS provides multiple node instance specifications. You can choose a certain number of node instances of specific specifications to suit your business needs. You can configure the node storage capacity within the configurable range based on the site requirements.

Scaling out
The new nodes and node storage capacity added to the cluster are also billed in pay-per-use mode.
Modifying node specifications
After node specifications are modified, nodes are billed based on new node specifications.

You can add new nodes or modify node specifications for a cluster in runtime. For details, see section Modifying Specifications in the Cloud Search Service User Guide.
