Abstract:
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for maintaining virtual machine metadata. One of the methods includes initializing a first virtual machine (VM) on a first host machine using one or more elements of user-specified initialization metadata. Upon receiving a notification that the first VM has published one or more elements of VM-generated metadata, one or more elements of VM-generated metadata are obtained. A request is received for the one or more elements of VM-generated metadata, and the one or more elements of VM-generated metadata are provided in response to the request.
Abstract:
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for associating one or more of a plurality of metadata collections with one or more respective identifiers, wherein each metadata collection includes one or more pairings of metadata attributes with metadata values, and wherein each identifier is one of a project identifier, a tag identifier or an instance identifier; identifying, based on identifier information associated with a virtual machine instance, one or more metadata values to be provided to the virtual machine instance, wherein the identifier information specifies one or more of a project identifier, a tag identifier and an instance identifier, and wherein each identified metadata value belongs to a metadata collection associated with an identifier that is specified in the identifier information; and providing, to the virtual machine instance, the identified one or more metadata values.

Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining a measure of resource usage by a virtual machine between startup and termination. The determination can be based on units of time in a sequence of contiguous units of time from the startup to the termination of a virtual machine. The actual utilization of a resource by the virtual machine during a unit of time may be compared to a resource utilization cap for the resource for the unit of time. If the utilization cap is exceeded, the excess resource utilization is determined. If the resource utilization cap is not exceeded, a resource utilization shortfall is determined. The measure of resource usage can be based on the number of units of time, the resource utilization cap for each resource, and the amount of excess resource utilization for each resource.
