Techniques are provided for a coordinated microservice system including a coordinator and multiple services, which interact with each other. Each of the services can have multiple execution instances, which run independently of each other. In operation, the current status of each instance is evaluated against one or more rules to determine whether the current status changes the topography of the services and updating the topography based on the changes. An execution plan is created for executing a command based on one or more predefined rules and the updated topography, where the execution plan includes one or more steps for executing the command on each instance of the service. The execution plan is executed on each instance of the service in accordance with the one or more predefined rules.

Some embodiments provide a novel method of performing health monitoring for resources associated with a global server load balancing (GSLB) system. This system is implemented by several domain name system (DNS) servers that perform DNS services for resources located at several geographically separate sites. The method identifies several different groupings of the resources. It then assigns the health monitoring of the different resource groups to different DNS servers. The method then configures each particular DNS server (1) to send health monitoring messages to the particular group of resources assigned to the particular DNS server, (2) to generate data by analyzing responses to the sent health monitoring messages, and (3) to distribute the generated data to the other DNS servers. The method in some embodiments is performed by a set of one or more controllers.

A method and system elects a master node from a plurality of nodes in a distributed system. A serverless elector function periodically outputs an election API call to a load balancer. The load balancer elects a master node from a plurality of candidate nodes each time the load balancer receives the election API call.

Network equipment for processing a request from a terminal configured to be connected to a network to which the network equipment can be connected is described. The network equipment includes a receiver configured to receive, from the terminal, a message part of the processing request, a relay agent configured to provide a network identification information into the received message, and a load balancer configured to forward the received message to one of a plurality of processing units of the network equipment, depending on workload information associated with the processing units. The processing units are further configured to retrieve, based on the network identification information extracted from the received message, context information from a database unit shared between the processing units and to process the received message according to a state of the processing request, the processing request state being retrieved from the context information.

A method, apparatus, and machine readable storage medium is disclosed for balancing loads among a plurality of virtual machines (VMs) from a central dispatcher, wherein the dispatcher receives data packets and maps the data packets to VMs selected from the plurality of VMs, using a weighted hash function, having an associated weighting for each VM and forwarding each packet to a VM accordingly, wherein a load balancer decrements a weighting for a VM, responsive to an indication of the load on the VM exceeding a first load threshold. Weightings can correspond to a number of bins associated with each VM. Weightings are adjusted in response to receiving invite and disinvite messages from the VMs, representing their respective loads.

A service request processing method, a related apparatus, and a system are provided. In the service request processing method provided in embodiments of the present invention, after receiving a service request reported by a network element, a load balancer first determines whether status information of a data node that corresponds to the service request indicates that the data node is available; and rejects, if the status information indicates that the data node is unavailable, to deliver the service request to an application node.

Disclosed are techniques and apparatuses that are configured to receive an indication that a web browsing session executing on an enterprise server needs additional information based on a request for additional information being sent to a client device. The request may include an identifier of the web browsing session and an identifier of an enterprise server that initiated the web browsing session. A globally unique identifier related to the web browsing session and an identifier of the enterprise server is stored in a common data store. The web browsing session may be paused when the web browsing session requests additional information from a client device. The client device may respond with the additional information. The system may provide the identifier of the enterprise server to a load balancing component so the identified web browsing session executing on the enterprise server may continue to be used.
