Pay-As-You-Go (PAYG) in Cloud
This section of the document provides a high level overview about verifying the Pay-as-you-go (PAYG) instance installed on the CloudEOS and vEOS Router products on various supported public platform.
Pay-as-you-go (PAYG) is a software consumption model supported by various public cloud provider to charge the consumer based on the usage. Other software consumption model on public cloud provider is Bring-your-own License(BYOL). Each vendor who publish their product on public cloud imposes a license requirement for the real usage of their product in which case, the consumer needs to get the BYOL from the vendor in order to use the product in the public cloud.
One of the major benefits of the PAYG method is that there are no wasted resources and consumer only pays for the services procured rather than provisioning for a fixed amount of resources that may or may not be used. Another advantage of PAYG is that, consumers can quickly deploy the product on the public cloud without the need to contact the vendor for license. Normally public cloud provider distinguish each published product by vendor with a unique ID. This unique ID is stored in the cloud provider metadata server. Vendor product should check for the unique ID to distinguish its products from BYOL and PAYG, and allow consumers to use without the requirement of license from vendor.
