Embodiments of the present disclosure relate to a method, a device and a computer program product for configuring service instances. The method comprises, at a computing device being used to implement a first service instance in a cloud environment, receiving, from a service manager of the cloud environment, a hypervisor related to a configuration of the first service instance. The method further comprises determining, based on the hypervisor, first configuration information for configuring the first service instance. The method further comprises configuring the first service instance with the first configuration information. With this method, service auto-deployment, auto-configuration and auto-association are realized, thereby improving user efficiency of configuring services and user experience.

According to an example, a service request may be received. A service template providing a service may be found according to type of the service in the service request. A resource zone matching the service template may be found from a resource pool. A network resource may be found from the resource zone matching the service template according to a network model role zone of a service unit in the service template. The network resource and the service unit belong to the same network model role zone and the network resource may match the service unit.

Methods, apparatus and articles of manufacture to provide client extensibility during provisioning of a composite blueprint are disclosed. An example virtual appliance in a cloud computing environment includes an orchestrator to facilitate provisioning of a virtual computing resource based on a blueprint, the provisioning associated with an event defined by the blueprint. The example virtual appliance also includes an event broker to maintain a set of subscribers to the event broker, each of the set of subscribers further subscribing to at least one event topic through the event broker, the event broker to trigger a notification of a first subscriber to a first event topic associated with the event when the event broker determines that the first subscriber is a blocking subscriber for the first event topic, the event broker to facilitate modification of the event by a blocking subscriber but not by a non-blocking subscriber.

Systems and methods described herein for automatic limit service increase in a multi-tenant cloud infrastructure environment. The systems and methods described herein provide for automatic approval of limit service increase requests that are either automatically generated based upon a tenant's usage of resources within the cloud infrastructure environment, or are received via, e.g., a user portal. Such automatic approval can be based upon a set of maximal limits that are computed based upon the tenant's current usage, level of subscription, or hard limit values.

A method for managing applications in a production host environment includes obtaining, by an application upgrade management system, an upgrade issue report for the application, applying a self-healing classification model to the upgrade issue report to obtain a state of the upgrade issue report, making a determination that the state indicates a self-healable state, based on the determination, performing a self-healing process on the application based on the upgrade issue report, and storing a resolution report based on results of the self-healing process.

In one example, a Network Functions Virtualization Orchestrator (NFVO) obtains a radio service descriptor defining communication parameters for a radio in a virtual Radio Access Network (vRAN). Based on the radio service descriptor, the NFVO determines whether a virtual Distributed Unit (vDU) that is configured in accordance with the communication parameters and a virtual Centralized Unit (vCU) that is configured in accordance with the communication parameters are already instantiated in the vRAN. If it is determined that the vDU or the vCU is not already instantiated, the NFVO automatically instantiates the vDU or the vCU in the vRAN.

A method of orchestrating a plurality of network resources for providing a requested network service in a mobile communications network. The method comprises monitoring service requests (202) and obtaining information comprising abstracted resources of radio domain, transport domain and computing domain (206). The method also comprises obtaining and processing a service description comprising a set of parameters defining the service to be provided (208) and identifying in the abstracted resources from the radio domain, transport domain and computing domain resources for delivering the service defined in the service description in a coverage area determined based on the service description (212).

Software performance can be automatically managed in a distributed computing environment. In one example, a system that can receive metrics information describing resource usage by a first instance of a service in a distributed computing environment. The system can also determine a quality-of-service (QoS) constraint for the service. The system can then modify a definition file based on the metrics information and the QoS constraint, the definition file being configured for deploying instances of the service in the distributed computing environment. The system can deploy a second instance of the service in the distributed computing environment using the modified definition file. As a result, the second instance can more closely satisfy the QoS constraint than the first instance.

Methods, systems, and computer-readable storage media for receiving a record including a set of attributes, each attribute having an attribute value, the record representing automatic execution of an IT process within a managed system, retrieving a model representing historical executions of the IT process and including a set of distribution parameters associated with a first type of attribute and a set of probability distributions associated with a second type of attribute, determining, for a first attribute, a first score based on distribution parameters and a value, determining, for a second attribute, a second score based on a probability distribution and a value, the second attribute being of the second type of attribute, and selectively indicating that the IT process is anomalous based on an outlier score.
