Abstract: The disclosed embodiments provide a task scheduling method and apparatus. Network resources needed for a task to perform cross-cluster reading and writing are analyzed to obtain usage information of the occupied network resources for reading and writing; and the task is scheduled according to the usage information of the network resources needed for reading and writing. Because the usage information of the network resources occupied for reading and writing respectively represent network resources that can be saved by the cluster where access data is located when the task is scheduled for reading and writing, it can be determined that the cluster to which the task is scheduled can enable the task to occupy less network resources, thereby solving the problem of high bandwidth usage across clusters in current systems.

Abstract: Techniques for migrating servers from customer networks into service provider networks are described. A backup proxy can be deployed in a customer's network and associated with one or more servers in the customer's network and with a server migration service of a service provider network. A customer can identify a server in the customer's network to migrate and the server migration service coordinates the migration with the backup proxy. The backup proxy can be instructed to obtain replication data for the server, obtain configuration data associated with the server, and upload the replication data and configuration data to the service provider network. The service provider network uses the replication data and configuration data to create a migrated copy of the server at the service provider network.

Abstract: Systems, methods, and software technology for governing resource utilization in a computing environment. In an implementation, a governance thread started by a job manager process identifies threads running within the job manager process and associates each of the threads with one of various jobs. The governance thread then tracks a resource utilization level of each of the jobs based on the resource utilization level of each of the threads associated with the job. When the resource utilization level of any of the jobs exceeds a threshold, the governance thread is able to shut down at least one of the threads associated with the job.
