Managing services instances
In some examples, information of a service instance provisioned or modified by a first system distinct from a management system is received, where the provisioning or modification of the service instance by the first system is initially unknown to the management system. As part of a binding phase, a model of the service instance is inferred. The management system manages a lifecycle of the service instance using the model and the policy.
1. A method executed by at least one processor, comprising:
as part of a discovery phase, receiving information of a service instance provisioned or modified by a first system distinct from a management system, wherein the provisioning or modification of the service instance by the first system is initially unknown to the management system;
as part of a binding phase, inferring a model representing the service instance provisioned or modified by the first system, wherein the model comprises nodes representing service components of the service instance, and links between the nodes representing relationships between the service components, and wherein inferring the model comprises accessing information of the service components of the service instance and determining how the service components are related to one another, and
managing, by the management system, a lifecycle of the service instance using the model.
2. The method of claim 1 , further comprising, as part of the binding phase, associating an action with a node of the model, wherein managing the lifecycle of the service instance further uses the action.
3. The method of claim 2 , wherein associating the action with the model comprises associating an application programming interface (API) that is useable by the management system to perform the action as part of the managing of the lifecycle of the service instance.
4. The method of claim 2 , wherein the action is a lifecycle action selected from among starting a service instance, moving a service instance, terminating a service instance, scaling operation of a service instance, monitoring a service instance, or managing a service instance.
5. The method of claim 1 , wherein the managing comprises one or both of monitoring the service instance and tracking the service instance.
6. The method of claim 1 , wherein receiving the information of the service instance as part of the discovery phase comprises obtaining, by the management system, the information of the service instance from a discovery engine that gathers information of attributes of service instances and relationships between the service instances and components of the service instances.
7. The method of claim 1 , wherein receiving the information of the service instance as part of the discovery phase comprises obtaining the information of the service instance from an engine that tracks assets of an environment and produces information about service instances that are tracked and dependencies of service components of the service instances.
8. The method of claim 1 , wherein receiving the information of the service instance as part of the discovery phase comprises obtaining the information of the service instance from an analytics system that performs analysis of service instances in an environment.
9. The method of claim 1 , wherein receiving the information of the service instance as part of the discovery phase comprises querying data from a configuration management database (CMDB).
10. The method of claim 1 , further comprising, as part of the binding phase, associating a policy with the model, the policy indicating any one or a combination of the service instance to monitor or manage, an entity to notify during the managing of the lifecycle of the service instance, a cloud zone in which the service instance is to be placed, or updating of the service instance.
11. The method of claim 1 , wherein the binding phase further comprises associating a user or organization with the service instance, and wherein associating the user or the organization with the service instance comprises associating a permission for the user or the organization to access or manage the service instance.
12. The method of claim 1 , further comprising:
receiving a user edit of the inferred model to perform one of:
adapt the model for a first environment to deploy the service instance in a different second environment, or
correct the model.
13. The method of claim 1 , wherein the management system is a cloud controller to manage a cloud, and wherein the provisioning of the service instance by the first system is responsive to delegation, by the cloud controller, of the provisioning or day-2 management to the first system.
14. The method of claim 1 , wherein the first system that provisioned or modified the service instance is selected from among a cloud controller, a PaaS module, a container controller, a program, a tool, or a device responsive to user input.
15. A non-transitory machine-readable storage medium storing instructions that upon execution cause a system to:
receive information of a service instance provisioned or modified by a provider system distinct from a management system, wherein the provisioning or modification of the service instance by the provider system is initially unknown to the management system;
as part of a binding phase,
create a model representing service components of the service instance provisioned or modified by the provider system, wherein the model comprises nodes representing the service components of the service instance, and links between the nodes representing relationships between the service components, and wherein creating the model comprises accessing information of the service components of the service instance and determining how the service components are related to one another, and
associate a lifecycle action with an element or a group of elements of the model; and
use the management system to manage a lifecycle of the service instance using the model and the lifecycle action.
16. The non-transitory machine-readable storage medium of claim 15 , wherein the instructions upon execution cause the system to associate a policy with the model, the policy relating to monitoring or managing the service instance.
17. A system comprising:
a processor; and
a non-transitory storage medium storing instructions executable on the processor to:
as part of a discovery phase, receive information of a service instance provisioned or modified by a first system distinct from a cloud controller, wherein the provisioning or modification of the service instance by the first system is initially unknown to the management system;
as part of a binding phase,
infer a model of the service instance provisioned or modified by the first system, wherein the model comprises nodes representing service components of the service instance, and links between the nodes representing relationships between the service components, and wherein inferring the model comprises accessing information of the service components of the service instance and determining how the service components are related to one another,
associate a policy with an element or group of elements of the model, and
associate a lifecycle action with an element or a group of elements of the model; and
use the cloud controller to manage a lifecycle of the service instance using the model, the policy, and the lifecycle action.
18. The system of claim 17 , wherein the model that is inferred is different from an initial model that the cloud controller is aware of, the initial model not reflecting the service instance as provisioned or modified by the first system distinct from the cloud controller.
19. The method of claim 1 , wherein the information of the service components accessed to infer the model comprises observed traffic between the service components.
20. The method of claim 1 , wherein the model that is inferred is different from an initial model that the management system is aware of, the initial model not reflecting the service instance as provisioned or modified by the first system distinct from the management system.
21. The non-transitory machine-readable storage medium of claim 15 , wherein the model that is created is different from an initial model that the management system is aware of, the initial model not reflecting the service instance as provisioned or modified by the provider system distinct from the management system.
