Notes – Image Resource• Image resource reflects OpenStack Glance “golden image” object. The purpose of

this resource is to allow accurate billing for the operating system usage• APS package should be able to report image usage, either collecting statistics from

Ceilometer (ideal) or by regularly reporting current state like “At given moment, tenant A uses 2 instances of image Windows2008” (works but can yield significant rounding error)

• The link between Image and UnmamagedVE should not to be set by PA but should be discovered from live OpenStack, as tenant may use image through OpenStack API bypassing PA

• Supported scenarios:• Provider can assign hourly cost of use to a particular image, and make certain images free in both

Flat and PAYG models• User can create server based on provider supplied image in Flat and PAYG model• User can upload own image and create server based on own image in Flat and PAYG subscription• Server creation from image through OpenStack API in Flat/PAYG subscription• Provider can create VPS subscription based on any provider-uploaded image• Provider can include certain images as paid add-on to a VPS subscription (“Windows 2008 costs

30 dollars a month”)• Unsupported scenarios

• Assigning hourly cost to user-uploaded image (other than storage cost reported by Ceilometer as storage use)

• Upload or use of custom images in VPS subscription• Server creation from image through OpenStack API in VPS subscription

Notes – Flavor Resource

• Flavor resource is used in VPS subscription only. One flavor per VPS service plan is created automatically in OpenStack by APS package and modified to reflect Service Plan modifications by Service Provider. Flavors reflecting Service Plans are only available to tenants running VPS subscriptions by automatically setting flavor visibility in OpenStack by APS package (using --is-public option and flavor-access-add command by APS package internally)

• Supported scenarios• Provider can setup a VPS service plan which will automatically

create a VPS when provisioned• Provider can setup several service plans for users to choose or

upgrade later

• Unsupported scenarios• Applying a custom flavor to a VPS subscription• Using a flavor from VPS subscription in Flat/PAYG subscription

Notes – Virtual Environment Resource

• We introduce two types of VE resources: UnmanagedVE and VPS. VPS resource used for creation of VPS subscriptions, UnmanagedVE – for Flat/PAYG subscriptions.

• Supported scenarios• Creating private flavors for a Flat/PAYG user• Assigning any available flavor to a server under Flat/PAYG

tenant/subscription• Managing and assigning flavors in PA UI in Flat/PAYG subscriptions• Managing and assigning flavors through OpenStack API in Flat/PAYG

subscriptions• Per-tenant billing and limiting of resources usage in Flat/PAYG

subscriptions regardless of ways to manage resources

• Unsupported scenarios• Using any information from or about flavors in Flat and PAYG

subscriptions for billing purposes• Modifying VPS subscription servers directly in OpenStack, or reflecting

these changes in billing
