  • Patent number: 11659019
    Abstract: Technologies are disclosed for resource mapping during URL changes in multi-tenant distributed computing systems. The distributed computing system may resolve a URL by using a tenant and/or site name extracted from the URL to retrieve an entry in a site map table. The entry includes an address to a database that contains the requested content. After a tenant or site name has been changed, or if the tenant or site have been moved, the distributed computing system will resolve pre-existing URLs to the old entry, resulting in a file not found error. In some embodiments, during an operation that changes a tenant or site name, a redirect URL containing the new tenant and/or site name is added to the old entry. When a request addressed to a URL containing the old tenant and/or site names is received, the distributed system sends a redirect response that includes the redirect URL.

  • Publication number: 20200249464
    Abstract: An optical device includes: first and second optical paths; a light reflective surface; and a linkage system. The first optical path is defined along a first optical axis. The second optical path is defined along a second optical axis. The light reflective surface is defined between the first and second optical paths.

  • Patent number: 10530860
    Abstract: Directory information and content for two separate tenants are merged by identifying a first of tenants as a hub tenant and a second of the tenants as a satellite tenant. The hub tenant is modified to include two instances, or data containers, one instance for the hub tenant and another instance for the satellite tenant. Directory merger logic re-associates identity account items in the satellite instance, with the hub instance, by replacing a tenant identifier in the identity account items of the satellite instance with a tenant identifier corresponding to the hub instance. Unique identifiers for users of the satellite instance are maintained unchanged. Content merger logic re-associates content items of the satellite instance with the hub instance by setting a tenant identifier for all satellite content items to the tenant identifier corresponding to the hub instance.

  • Publication number: 20190098107
    Abstract: Distributed computing systems, computing devices, and associated methods of operations implementing geographic location based computing asset provisioning are disclosed herein. In one embodiment, a provisioning server is configured to retrieve, from a directory service, a record of user account data containing data representing a pre-configured deployment location at which user data of the requested computing service is to be stored. The provisioning server is also configured to determine whether a current geographic location of the provisioning server is within a geographic boundary of the deployment location and in response to determining that the current geographic location of the provisioning server is within a geographic boundary of the deployment location, deploy computing assets at the current geographic location to allow user data of the computing service to be stored at the pre-configured deployment location to satisfy data residency regulations.

  • Publication number: 20100199357
    Abstract: Various technologies and techniques are disclosed for increasing security in execution environments. A system is described for handling DLL calls made from untrusted code. An execution environment instantiates a lower trust process when a high trust process determines a need to call untrusted code. When the untrusted code calls a method in an original DLL, the execution environment loads a shim DLL into the lower trust process. The shim DLL has a clone of the method from the original DLL. A method for increasing security when processing calls from untrusted code is described. A shim DLL is created from an original DLL, and is deployed so an execution environment will load the shim DLL instead of the original DLL. When an execution environment receives a call from a caller DLL to the original DLL, the call is routed through the shim DLL. A pluggable validation system is also described.
