Abstract: A system and procedure to automatically enforce policy in distributed multi-computer service applications. Such service applications include multiple software modules that execute on multiple computers. The computers have access to communications media that allow data communications between the computers. Logical ports are configured on different modules according to a logical model of the multi-computer service application. Each logical port is defined by port software. Logical data connections between the logical ports are configured in accordance with the logical model. Each port is configured to communicate through different numbers of logical data connections without modifying the port software. In response to the occurrence of a condition, a module sends an event notification to a policy module. The policy module responds to the notification by formulating a request for one or more destination modules. The policy module provides the request to an output port of the policy module.

Abstract: A system facilitates the design and implementation of large-scale applications, such as Internet Services and Websites, for distributed computer systems, such as server data centers, Internet data centers (IDCs), Web farms, and the like. The system has a modeling system and a deployment system. The modeling system permits developers to architect the hardware and software used to implement the applications in an abstract manner. The modeling system defines a set of components used to describe the functionality of an application. The model components are arranged and interconnected to form a scale-independent logical model of the application. Once a logical model is created, the deployment system uses the logical model to automatically deploy various computer/software resources to implement the application. The deployment system converts each of the model components into one or more instances that correspond to physical resources.

Abstract: A multi-tiered server management architecture is employed including an application development tier, an application operations tier, and a cluster operations tier. In the application development tier, applications are developed for execution on one or more server computers. In the application operations tier, execution of the applications is managed and sub-boundaries within a cluster of servers can be established. In the cluster operations tier, operation of the server computers is managed without concern for what applications are executing on the one or more server computers and boundaries between clusters of servers can be established. The multi-tiered server management architecture can also be employed in co-location facilities where clusters of servers are leased to tenants, with the tenants implementing the application operations tier and the facility owner (or operator) implementing the cluster operations tier.

Abstract: A multi-tiered server management architecture is employed including an application development tier, an application operations tier, and a cluster operations tier. In the application development tier, applications are developed for execution on one or more server computers. In the application operations tier, execution of the applications is managed and sub-boundaries within a cluster of servers can be established. In the cluster operations tier, operation of the server computers is managed without concern for what applications are executing on the one or more server computers and boundaries between clusters of servers can be established. The multi-tiered server management architecture can also be employed in co-location facilities where clusters of servers are leased to tenants, with the tenants implementing the application operations tier and the facility owner (or operator) implementing the cluster operations tier.

Abstract: In an exemplary device implementation, a device includes: a connection migrator that is configured to migrate connections away from the device; the connection migrator capable of precipitating a compilation of protocol state for a connection across a protocol stack; the connection migrator adapted to aggregate the compiled protocol state with data for the connection into an aggregated connection state; the connection migrator further capable of causing the aggregated connection state to be sent toward a target device. In an exemplary media implementation, processor-executable instructions direct a device to perform actions including: obtaining at least a portion of a source/destination pair from a packet; accessing an encapsulation mapping table using the at least a portion of the source/destination pair to locate an encapsulation mapping entry; extracting a flow identifier from the encapsulation mapping entry; and replacing part of the packet with the flow identifier to produce an encapsulated packet.

Abstract: Systems and methods to enforce policy in a multi-computer service application are described. In one aspect, a scale-independent logical model of an application is generated. The application is for implementation in a distributed computing system. The scale-independent logical model includes multiple components representing logical functions of the application and intercommunication protocols. The model components are converted into one or more instances representative of physical resources used to implement the logical functions. The instances specify information such as communication ports on the physical resources and communication paths that link the physical resources.

Abstract: Systems and methods to enforce policy in a multi-computer service application are described. The application includes multiple software modules that execute on multiple computers. The multi-computer service application has access to a communications medium that allows data communications between different ones of the computers. The software modules have logical input and output ports and logical data connections between modules. Each logical port is defined by port software. In one aspect, a particular module sends a notification to a policy module. Responsive to the notification, the policy module (a) determines a request for one or more destination modules, and (b) provides the request to an output port of the policy module. The output port forwards the request to input ports of a plurality of the modules in accordance with the logical data connections.

Abstract: In an exemplary method implementation, a method includes: receiving a packet requesting a new connection at a forwarding component; sending the packet from the forwarding component to a classifying component; selecting, by the classifying component, a route for the new connection; and plumbing, by the classifying component, the route for the new connection by causing a new entry to be added in a local routing table of the forwarding component. In an exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, enable a system to perform actions including: receiving a first packet for a connection at first forwarding functionality; plumbing a route for the connection at the first forwarding functionality; receiving a second packet for the connection at second forwarding functionality; and plumbing the route for the connection at the second forwarding functionality using a distributed session tracking table.

In another exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, enable a system to be configured such that different percentages of system resources may be allocated to different network-load-balancing functions. In yet another exemplary media implementation, one or more processor-accessible media include processor-executable instructions for network load balancing that, when executed, enable a system to gradually increase a percentage of total computing resources that is devoted to the network load balancing.
