A method of upgrading an application in a software-defined data center (SDDC) includes: deploying, by lifecycle management software executing in the SDDC, a second appliance, a first appliance executing services of the application at a first version, the second appliance having services of the application at a second version, the services in the first appliance being active and the services in the second appliance being inactive; expanding, by the lifecycle management software, state of the first appliance to support both the services at the first version and the services at the second version; replicating, by the lifecycle management software, the state of the first appliance to the second appliance; performing, by the lifecycle management software, a switchover to stop the services of the first appliance and start the services of the second appliance; and contracting, by the lifecycle management software, state of the second appliance to remove a portion unused by the services at the second version.

Examples of enterprise management using managed virtual machines for virtualized applications are described. In some examples, a managed virtual machine is executed on a host device and enrolled with a management service. A virtualized application drive is stored in the managed virtual machine. A launch agent executed within the managed virtual machine detects an application access request corresponding to user interaction with a host operating system of the host device. The application volumes launch agent accesses the virtualized application drive and launches the virtualized application corresponding to the application access request.

A card rendering method includes that an electronic device sends a request for obtaining related information of a target card to a server, and receives related information that is of a target card and that is sent by the server. The electronic device renders the target card based on a first layout snapshot, displays the target card on a display screen, parses a first file package set of the target card to obtain a second rendering instruction set, selects a rendering instruction in the second rendering instruction set other than a first rendering instruction set, renders again the target card according to the selected rendering instruction, and updates the target card displayed on the display screen.

In an example, a network controller for an SDN architecture system includes processing circuitry of a central cluster of first one or more compute nodes; a configuration node configured for execution by the processing circuitry; a control node configured for execution by the processing circuitry. The configuration node includes a custom API server to process requests for operations on custom resources for SDN architecture configuration. Each of the custom resources for SDN architecture configuration corresponds to a type of configuration object in the SDN architecture system. The control node, in response to detecting an event on an instance of a first custom resource of the custom resources, obtains configuration data for the instance of the first custom resource and configures a corresponding instance of a configuration object in a workload cluster of second one or more compute nodes. The first and second compute nodes may be distinct.

A proxy server automatically includes web applications in web pages at the network level. The proxy server receives, from a client device, a request for a network resource at a domain and is hosted at an origin server. The proxy server retrieves the requested network resource. The retrieved network resource does not include the web applications. The proxy server determines that the web applications are to be installed within the network resource. The proxy server automatically modifies the retrieved network resource to include the web applications. The proxy server transmits a response to the client device that includes the modified network resource. The network resource may remain unchanged at the origin server.

A multitenant infrastructure server (MTIS) is configured to provide an environment to execute a computer routine of an arbitrary application. The MTIS receives a request from a webtask server to execute the computer routine in a webtask container. The computer routine is executed in the webtask container at the MTIS. Upon successful execution of the computer routine, a result set is returned to the webtask server. If the execution of the computer routine is unsuccessful, an error notification is returned to the webtask server. The resources consumed during the execution of the computer routine are determined. The webtask container is destroyed to prevent persistent storage of the computer routine on the MTIS.

A load balancing method and a related device is provided. The method includes: determining topology information of each of a plurality of smallest management units pods in a load balancing cluster to which a first node belongs, where the plurality of pods are distributed on at least two nodes; determining a weight of each of the plurality of pods based on the topology information of each pod; and selecting a target pod from the plurality of pods based on the weight of each pod, where the target pod is configured to process a currently to-be-processed task in the first node. In embodiments of this application, network overheads can be reduced when a task request is allocated.

A collection configuration management system can be used to manage one or more monitoring objects, such as tags, included in one or more content objects. The collection configuration management system can compartmentalize monitoring object configurations into a monitoring object bundle that may be executed as a result of loading the one or more content objects. The monitoring object bundle can be generated to include one or more monitoring objects, as well as monitoring object management loader functionality.

A communication apparatus 100 includes a firmware storage area that stores firmware of the communication apparatus 100, an update storage area 142b used for update processing of updating the firmware, a communicator 130 that receives a difference file indicating details of update for the firmware through wireless communication, and an update processor 141b that executes the update processing based on the difference file. The update processor 141b divides the firmware stored in the firmware storage area into a plurality of blocks and executes the update processing for each of the plurality of blocks using the update storage area 142b.

A communication apparatus 100 that performs wireless communication maintains, in an inactive state, a firmware update function of acquiring an update file used for a firmware update of the communication apparatus by accessing a server 300, performs transmission processing of transmitting sensor data obtained by a sensor to the server, and activates the firmware update function based on activation information acquired from the server at the time of the transmission processing.
