Systems and methods described herein support a usage calculation process in a cloud infrastructure environment. The usage calculation process can be used to determine whether a requested transaction that targets a compartment within a tree-structure of compartments violates any compartment quota or limit within parent compartments within the tree-structure.

Techniques for utilizing Software-Defined Networking (SDN) controllers and network border leaf nodes of respective cloud computing networks to configure a data transmission route for a multicast group. Each border leaf node may maintain a respective external sources database, including a number of records indicating associations between a multicast data source, one or more respective border leaf nodes disposed in the same network as the multicast data source, and network capability information. A border leaf node, disposed in the same network as a multicast data source, may broadcast a local source discovery message to all border leaf nodes in remote networks to which it is communicatively coupled. A border leaf node may also communicate network capability information associated with one or more remote networks to a local SDN controller. The SDN controller may utilize the network capability information to configure a data transmission route to one or more destination nodes.

To dynamically allow chaining of logical processing units comprising endpoints, at least a type of an endpoint, and address information whereto connect the endpoint is configured, wherein the type of the endpoint is either a host port type or a logical processing unit type. During offloading from a central processing unit one or more functions to be performed by at least one further processing unit, the central processing unit is interacting with the one or more logical processing units via endpoints of the host port type and logical processing units are interacting via endpoints of the logical processing unit port type, the interaction using the address information.

A method, computer system, and a computer program product for deploying a plurality of microservices across a service infrastructure having a plurality of resources is provided. The present invention may include determining at least one dependency of the plurality of microservices. The present invention may include for each resource of the plurality of resources, determining an outage distribution descriptive of an availability of the resource with respect to time. The present invention may include based on the outage distribution associated with each resource and the at least one dependency of the plurality of microservices, determining a deployment configuration of the plurality of microservices across the resources of the service infrastructure.

Example methods and systems for logical network health check. One example may comprise obtaining network configuration information and network realization information associated with a logical network; processing the network configuration information and the network realization information to determine the following: (a) network configuration health information specifying a network configuration issue and a first remediation action; and (b) network realization health information specifying a network realization issue and a second remediation action; and providing, to a user device, multiple user interfaces (UIs) specifying the first health information and the second health information along with a visualization of the logical network. In response to detecting an instruction initiated by the user device using at least one of the multiple UIs, the first remediation action or the second remediation action may be performed.

A method of reserving hardware resources for management appliances of a software-defined data center (SDDC) that have been deployed onto one or more hosts of a cluster of hosts, includes reserving hardware resources of the cluster for a resource pool that has been created for the management appliances, the hardware resources including at least processor resources of the hosts and memory resources of the hosts, and assigning the management appliances to the resource pool created for the management appliances. The management appliances share the hardware resources of the cluster with one or more other resource pools and, after the steps of reserving and assigning, are allocated at least the hardware resources that have been reserved for the resource pool created for the management appliances.

Methods and apparatus for client-directed placement of remotely configured service instances are described. One or more placement target options are selected for a client of a network-accessible service based on criteria such as service characteristics of the placement targets. The selected options, including a particular placement target that includes instance hosts configurable from remote control servers, are indicated programmatically to the client. A determination is made that a service instance is to be configured at the particular placement target on behalf of the client. A remote control server is configured to issue administrative commands to an instance host at the particular placement target to configure the service instance.

Techniques are disclosed for generating intent-based policies and applying the policies to traffic of a computer network. In one example, a policy controller for the computer network receives traffic statistics for traffic flows among a plurality of application workloads executed by a first set of computing devices. The policy controller correlates the traffic statistics into session records for the plurality of application workloads. The policy controller generates, based on the session records for the application workloads, application firewall policies for the application workloads. Each of the application firewall policies define whether traffic flows between application workloads are to be allowed or denied. The policy controller distributes the application firewall policies to a second set of one or more computing devices for application to traffic flows between instances of the application workloads.

A system configured to track network slicing operations within a 5G communication network includes processing circuitry configured to determine a network slice instance (NSI) associated with a QoS flow of a UE. The NSI communicates data for a network function virtualization (NFV) instance of a Multi-Access Edge Computing (MEC) system within the 5G communication network. Latency information for a plurality of communication links used by the NSI is retrieved. The plurality of communication links includes a first set of non-MEC communication links associated with a radio access network (RAN) of the 5G communication network and a second set of MEC communication links associated with the MEC system. A slice configuration policy is generated based on the retrieved latency information and slice-specific attributes of the NSI. Network resources of the 5G communication network used by the NSI are reconfigured based on the generated slice configuration policy.
