Managing storage volume in a virtual computing infrastructure
Techniques are provided for authorizations in a virtual computing infrastructure using a federation token service. The techniques may include receiving a request for a launch plan from a user for launching instances in a plurality of sites, determining object permissions required for actions to be performed to launch one or more of the instances at each site of the plurality of sites, contacting an authorization caching service to obtain authorization tokens for each of the determined object permissions required for the actions, receiving the authorization tokens for each of the determined object permissions required for the actions, and forwarding the request to each site of the plurality of sites with an authentication token and the authorization tokens for each of the determined object permissions required for the actions to be performed to launch the one or more of the instances at each site of the plurality of sites.
1. A non-transitory computer-readable storage medium storing instructions which, when executed by one or more processors, cause the one or more processors to:
receive, at a site controller of a computing system, a request to attach a virtual storage volume to an instance of an object;
obtain, by the site controller, a network location and storage area network protocols supported by the virtual storage volume;
augment, by the site controller, the request with the network location and the storage area network protocols to generate an augmented request;
forward, by the site controller, the augmented request to a storage cluster controller of the computing system based upon an internal mapping between instances and storage clusters;
forward, by the storage cluster controller, the augmented request to a storage node controller responsible for a node on which the instance of the object is hosted;
create, by the storage node controller, an attachment of a storage area network to the virtual storage volume based on the network location and the storage area network protocols supported by the virtual storage volume; and
attach, by the storage node controller, the virtual storage volume and the attached storage area network to the instance as a virtual block device.

6. The non-transitory computer-readable storage medium of claim 1 , wherein the one or more processors are further caused to in response to receiving the request, determine whether the request is authorized based on stored permissions that define whether a user is allowed to attach the virtual storage volume to the instance of the object.
7. The non-transitory computer-readable storage medium of claim 1 , wherein the site controller obtains the network location and the storage area network protocols supported by the virtual storage volume from a storage site controller that keeps track of an aggregate state of the storage clusters.
8. A system comprising:
one or more processors; and

obtaining, by the site controller, a network location and storage area network protocols supported by the virtual storage volume;
augmenting, by the site controller, the request with the network location and the storage area network protocols to generate an augmented request;
forwarding, by the site controller, the augmented request to a storage cluster controller of the computing system based upon an internal mapping between instances and storage clusters;
forwarding, by the storage cluster controller, the augmented request to a storage node controller responsible for a node on which the instance of the object is hosted;
creating, by the storage node controller, an attachment of a storage area network to the virtual storage volume based on the network location and the storage area network protocols supported by the virtual storage volume; and
attaching, by the storage node controller, the virtual storage volume and the attached storage area network to the instance as a virtual block device.
9. The system of claim 8 , wherein the object is (i) a machine image executed as a virtual machine, (ii) executed as code, or (iii) an accessible data store.
10. The system of claim 8 , wherein the storage node controller is registered with the storage cluster controller, which manages a fleet of storage node controllers.

13. The system of claim 8 , wherein the method further includes:
in response to receiving the request, determining, by the computing system, whether the request is authorized based on stored permissions that define whether a user is allowed to attach the virtual storage volume to the instance of the object.
14. The system of claim 8 , wherein the site controller obtains the network location and the storage area network protocols supported by the virtual storage volume from a storage site controller that keeps track of an aggregate state of the storage clusters.
15. A method comprising:
receiving, at a site controller of a computing system, a request to attach a virtual storage volume to an instance of an object;
