Abstract: Methods and apparatus for interfaces to manage last-mile connectivity and dynamic reconfiguration for direct network peerings. A system may include a data center, endpoint routers and a connectivity coordinator. The coordinator implements an interface defining connectivity operations. The coordinator receives a request for dedicated connectivity to data center resources, formatted according to the interface. The coordinator determines a connectivity provider to provide last-mile connectivity to the requester, and transmits a notification identifying the selected connectivity provider.

Abstract: A vendor of virtual machine images accesses a virtual computer system service to upload a digitally signed virtual machine image to a data store usable by customers of the virtual computer system service to select an image for creating a virtual machine instance. If a digital certificate is uploaded along with the virtual machine image, the virtual computer system service may determine whether the digital certificate has been trusted for use. If the digital certificate has been trusted for use, the virtual computer system service may use a public cryptographic key to decrypt a hash signature included with the image to obtain a first hash value. The service may additionally apply a hash function to the image itself to obtain a second hash value. If the two hash values match, then the virtual machine image may be deemed to be authentic.

Abstract: Methods and apparatus for securing client-specified credentials at cryptographically-attested resources are described. An indication is obtained that resources deployed for execution of a compute instance of a multi-tenant computing service at an instance host of a provider network meet a client's security criteria. An encrypted representation of credentials to be used at the compute instance to implement operations on behalf of a client is received at the instance host. The credentials are extracted from the encrypted representation using a private key unique to the instance host, used for the operations, and then removed from the instance host without being saved in persistent memory.
