摘要： A method, system and computer program product for dynamically building a set of compute nodes to host a user's workload. An administrative server receives workload definitions that include the types of workloads that are to be run in a cloud group as well as a number of instances of each workload the cloud group should support. These workload definitions are used to determine the virtual machine demands that the cloud group will place on the cloud environment. The administrative server further receives the demand constraints, placement constraints and license enforcement policies. The administrative server identifies a set of compute nodes to host the user's workload based on the virtual machines demands, the demand constraints, the placement constraints and the license enforcement policies. In this manner, a set of compute nodes is dynamically built for consideration in forming a cloud group without the user requiring knowledge of the cloud's composition.

摘要： Techniques are disclosed for load balancing based on call length in networks such as those networks handling telephony applications. By way of example, one method for directing requests associated with calls to servers in a system comprised of a network routing calls between at least one caller and at least one receiver wherein the network comprises a load balancer sending requests to a plurality of servers comprises the following steps. A first request of a call is received. A server s1 is selected to receive the request based on an estimated duration of the call. Another method for directing requests associated with calls to servers in a system comprised of a network routing calls between at least one caller and at least one receiver wherein the network comprises a load balancer sending requests to a plurality of servers comprises the following steps. Information is maintained regarding load assigned to a plurality of servers. A first request of a call is received. A server s1 is selected to receive the request based on the maintained information. The request is sent to server s1. The information regarding load is updated based on an estimated length of the call.

By way of example, such techniques direct requests associated with calls to servers in a system comprised of a network routing calls between a plurality of callers and at least one receiver wherein a load balancer sends requests associated with calls to a plurality of servers as follows. A request associated with a call, a caller, or a receiver is received, depending on the particular load balancing technique. A server is selected to receive the request. A subsequent request is received. A determination is made whether or not the subsequent request is associated with the call, the caller, or the receiver, depending on the particular load balancing technique. The subsequent request is sent to the server based on determining that the subsequent request is associated with the call, the caller, or the receiver, again depending on the particular load balancing technique.

摘要： Provides control of the workload, flow control, and concurrency control of a computer system through the use of only external performance monitors. Data collected by external performance monitors are used to build a simple, black box model of the computer system, comprising two resources: a virtual bottleneck resource and a delay resource representing all non-bottleneck resources combined. The service times of the two resource types are two parameters of the black box model. The two parameters are evaluated based on historical data collected by the external performance monitors. The workload capacity that avoids saturation of the bottleneck resource is then determined and used as a control variable by a flow controller to limit the workload on the computer system. The workload may include a mix of traffic classes. In such a case, data is collected, parameters are evaluated and control variables are determined for each of the traffic classes.
