摘要： A cluster of computing nodes communicate through an unsecure network by selectively sending information in encrypted and unencrypted formats. Heartbeat packets are sent between the computing nodes to coordinate operation of the computing nodes and using an encrypted format. Messages are selectively sent between the computing nodes with an encrypted or an unencrypted format based upon one or more predetermined factors, such as an end user selection, the type of message or the load at the computing nodes.
摘要翻译：一组计算节点通过选择性地发送加密和未加密格式的信息通过不安全的网络进行通信。在计算节点之间发送心跳数据包以协调计算节点的操作并使用加密格式。基于一个或多个预定因素，例如最终用户选择，消息的类型或计算节点处的负载，有选择地以计算节点之间的加密或未加密格式发送消息。

摘要： Responsive to a cluster manager for a particular node from among multiple nodes allocating at least one leased resource for a resource group for an application workload on the particular node, on fallover of the resource group from another node to the particular node, setting a timer thread, by the cluster manager for the particular node, to track an amount of time remaining for an initial lease period of the at least one leased resource. Responsive to the timer thread expiring while the resource group is holding the at least one leased resource, maintaining, by the cluster manager for the particular node, the resource group comprising the at least one leased resource for an additional lease period and automatically incurring an additional fee, only if the particular node has the capacity to handle the resource group at a lowest cost from among the nodes.

摘要： The Authorized Authorization Set System comprising a modified operating system, a command table containing authorized authorization sets, and a modified RBAC security system, eliminates the need for inherited privileges that must be passed to subcommands in order for the command to run. The modified operating system accesses a table containing authorized authorization sets which identify the privileges for all subcommands within a command. When a user is assigned an accessauth for a command, and a sub-command is a privileged sub-command, the privileged sub-command is only run when the accessauth of the sub-command is included in the authorized authorization set of the command.
