Techniques for sharing virtual machine (VM) resources
View Patent ↗Techniques for sharing virtual machine (VM) resources are provided. A relative location for a resource within a VM is created; the relative location dynamically resolves to a particular physical location when a principal requests access to the resource at runtime. The principal is located outside an environment associated with the VM. Authentication and access restrictions are dynamically enforced against the requests made by the principal before a connection is permitted between the principal and the resource (the resource located within the environment of the VM).
1. A method, the method comprising:
receiving, by a processor, a request to create an artifact for a resource, the request received from a requestor of a virtual machine (VM) and the resource available through the VM;
creating, by the processor, the artifact as a logical reference to the resource, the logical reference dynamically resolved to a particular location for the resource within an executing instance of the VM when the artifact is subsequently provided by a requesting principal that is external to the VM, the artifact includes a bearer type, owner data of the artifact signed by a private key of an owner, receiver data of the artifact encrypted by a public key of an identity provider, and resource data encrypted by the public key of the identity provider and signed by the private key of the owner; and
supplying, by the processor, the artifact to the requestor within the VM, the requestor subsequently shares the artifact with the requesting principal for the requesting principal to use to gain access to the resource being shared from the VM.
2. The method of claim 1 , wherein receiving further includes parsing from the request a unique identifier for the VM, a relative location or offset for the resource within the VM, and an identifier for the requesting principal.
3. The method of claim 2 , wherein receiving further includes parsing from the request, access limitations levied by the requestor on access to the resource and cache availability for the resource.
4. The method of claim 1 , wherein creating further includes assembling the artifact to include: authentication and authorization policies for enforcement when the artifact is presented by the requesting principal, a relative location that resolves to the logical reference, a requesting principal identity, and a requestor identity.
5. The method of claim 4 , wherein assembling further includes encrypting and digitally signing all or selective portions of the artifact.
6. The method of claim 5 , wherein encrypting and digitally signing further includes sending the encrypted and signed artifact to a VM access layer that the VM access layer also digitally signs and returns.
7. The method of claim 1 , wherein supplying further includes pushing the artifact to a requestor portal that requestor interacts with and that the requestor uses to download the artifact for sharing with the requesting principal.
8. The method of claim 1 , wherein supplying further includes instructing the requestor to deliver the artifact to the requesting principal via a specific communication channel.
9. The method of claim 8 , wherein instructing further includes identifying the communication channel for the requestor as an out-of-band communication that communicates to the requesting principal via one or more of: email communication, a web site communication, a text message, and an instant message.
10. The method of claim 1 further comprising:
receiving, by the processor, the artifact from the requesting principal after the requestor shares the artifact with the requesting principal;
decrypting, by the processor, portions of the artifact to verify permission of the requesting principal to access the resource and to dynamically resolve the particular location of the resource within the VM; and
facilitating a connection between the requesting principal to the resource located at the particular location within the VM.
