In some examples, one or more processors are able to communicate with a plurality of user devices associated with a plurality of users, and the one or more processors may provide a plurality of applications executable in association with the plurality of users. For each application of the plurality of applications, the one or more processors may determine data access permissions for the application. Additionally, the one or more processors may determine data access permissions for individual users of a plurality of users. Based on the data access permissions for the plurality of users and the data access permissions for the plurality of applications, the one or more processors may generate a data structure including data access permissions for each of the applications. The generated data access permissions for each of the applications may be customized for, or otherwise specific to, individual users of the plurality of users.

Application access control configuration

A system receives a quota request in which a tenant, one or more locations, and a capacity upper limit related to a requested quota are designated, executes conflict determination n based on quota information, and adds information related to the requested quota to the quota information when a result of the conflict determination is false. The quota information includes information representing a tenant, one or more locations, and a capacity upper limit for each quota of the plurality of storage devices at the plurality of locations. For each of the plurality of locations, a capacity usable by the tenant among a capacity of the storage device at the location is equal to or less than the capacity upper limit of the quota corresponding to the location and the tenant.

Quota management system and quota management method

In some examples, a computing device may determine a replication criteria for replication of user information and/or resource information between a first computing site and a second computing site. The computing device may perform the replication between the first computing site and the second computing site based on the replication criteria. Further, the computing device may determine at least one of a user correspondence or a resource correspondence between the first computing site and the second computing site based on performing the replication. The computing device may replicate permission information between the first computing site and the second computing site based at least on the user correspondence and/or the resource correspondence.

Permission synchronization across computing sites based on user and resource correspondence

A distributed storage system comprises a plurality of storage nodes which includes multiple resources including multiple kinds of resources. Each of the multiple storage nodes among the plurality of storage nodes is configured to execute an aggregation task which has been assigned to the storage node among aggregation tasks, Each of the aggregation tasks is a task for aggregating statistics relating to a resource among the multiple resources which corresponds to the task, to the storage node to which the task has been assigned.

Method and distributed storage system for aggregating statistics

In some examples, a computing device may determine an estimated available capacity at a future time for respective storage nodes of a plurality of storage nodes. The computing device may compare the estimated available capacity of a first one of the storage nodes at the future time with the estimated available capacity of a second one of the storage nodes at the future time. Based at least in part on determining that a difference between the estimated available capacity of the first storage node and the estimated available capacity of the second storage node exceeds a threshold difference, determining an amount of data to move from the first storage node. The computing device may cause data to be moved from the first storage node to cause the difference between the available capacity of the first storage node and the available capacity of the second storage node to be reduced.
