Embodiments of the present disclosure relate to a method, system and computer program product for offloading a workload between computing environments. According to the method, a workload of a target function of a service provisioned in a first computing environment is determined. A processing capacity of the service available for the target function in the first computing environment is determined. In accordance with a determination that the workload exceeds the processing capacity, at least one incoming request for the target function is caused to be routed to a target instance of the target function, the target instance of the target function being provisioned in a second computing environment different from the first computing environment.

Workload offloading between computing environments

A method for load balancing network traffic. First network address translation rules are executed with respect to a first data packet of the network traffic to translate initial address space data thereof, with respect to an initial destination network address and port identifier. An entry is generated with respect to the first data packet that includes data related to the translated destination network address and port identifier, and an initial source network address and port identifier. A second data packet is received from a client. The generated entry is identified and implemented in executing second network address translation rules with respect to the second data packet, to translate address space data thereof with respect to an initial destination network address and port identifier, for routing thereof to the host, and upon servicing, for routing thereof directly to the client.

Load balancing in data hosting systems

In some embodiments, the present disclosure provides for accelerating cross-sited resources in an accelerated document. In some embodiments, a set of rules is created to determine which cross-site resources will be accelerated. Using the rules, a first cross-site resource is selected for acceleration. The cross-site resource is cached on a CDN edge server. A link for a first cross-site resource is wrapped so that a client will be directed to retrieve the cross-site resource from the CDN edge server. The client receives the cross-site resource directly from the CDN edge server.

Content acceleration for cross-site resources by CDN

A load-balancer instance is instantiated in a network virtualization edge (NVE) in a software defined network (SDN). A forwarding table in the NVE is modified to indicate that a next hop for a packet having a destination address of the load-balancer instance is to be resolved by the load-balancer instance. From a portion of the packet, and using the load-balancer instance, a value usable to select a singular next hop to a first real server in a pool of real servers managed by the load-balancer instance is determined. The packet is forwarded, using the modified forwarding table, the packet through an underlay of the SDN such that the packet tunnels from the NVE to a first NVE, the second NVE hosting the first real server.

Distributed load-balancing for software defined networks

Operating a message queue cluster having multiple nodes. A messaging request from a client is obtained by one or more processors, the messaging request to be routed to one of multiple nodes in a cluster. The one or more processors parse the messaging request to determine whether the messaging request should be routed to an other node. A messaging request is obtained from a client by one or more processors, the messaging request to be routed to one of multiple nodes in a cluster. The messaging request is parsed by one or more processors to determine whether the messaging request should be routed to an other of the multiple nodes in the cluster. The messaging request is routed by one or more processors in response to a determination that the messaging request should be routed to the other one of the multiple nodes in the cluster.

Operating a message queue cluster having multiple nodes

In one embodiment, a system includes a processing circuit and logic integrated with and/or executable by the processing circuit that causes the processing circuit to receive a congestion notification message from a first virtual switch of a first server indicating that a first virtual machine (VM) hosted by the first server is overloaded. The logic also causes the processing circuit to advertise a congestion status of the first VM in a congestion status message to one or more virtual switches in a network in response to receiving the congestion notification message. Moreover, the logic causes the processing circuit to cause all virtual switches in the network except for the first virtual switch to stop sending traffic destined for the first VM while the first VM is overloaded without restricting sending traffic that is destined for other VMs hosted by the first server.
