Abstract: This application relates to load balancing for a number of partitions of a network-based storage service. Each partition includes a number of server devices and/or network devices located in a data center and configured to provide access to storage resources hosted within the data center. User accounts are assigned to a particular partition such that requests related to a particular user account are routed to that partition. Periodically, a load balancing algorithm is executed to re-assign user accounts to different partitions to rebalance resource consumption across the different partitions. The load balancing algorithm can balance resource consumption for any number of resource types by generating a vector of resource utilization parameters for each user account, sorting the plurality of user accounts into clusters based on the vectors, and mapping at least some user accounts to different partitions.

Abstract: A messaging system uses a cloud storage backup system for messages and a temporary storage for messages that are not deliverable to offline devices at the time that the messages are sent by one or more messaging servers. The messages are backed up through a synchronization process that transfers a batch of a plurality of messages rather than a single message or an entire database of messages. A conversation state can be synchronized first before synchronizing messages through the transfer of one or more batches of messages.

Abstract: This application relates to a client-server architecture that enables file sharing between an instructor and a class. The files are stored in a storage service accessible via a network, and a separate copy of each file can be shared with each student in the class. In order to facilitate the sharing of multiple copies of the file, a share pool is created in a partition of the storage service allocated to the instructor. The share pool includes a number of stub files that are placeholders for clones of the shared file. A share handler service receives a request to share a file with a class, requests a number of stub files from the share pool, and utilizes the number of stub files to generate clones of the shared file in the partition of the storage service. Students are then granted access to the clones in the partition.
