Abstract

A system and method can deploy and manage software services in virtualized and non-virtualized environments. The system provides an enterprise application virtualization solution that allows for centralized governance and control over software and Java applications. Operations teams can define policies, based on application-level service level agreements (SLA) that govern the allocation of hardware and software resources to ensure that quality of service (QoS) goals are met across virtual and non-virtualized platforms. The system use a rules engine that can compare administrator defined constraints with runtime metrics; generate events when a constraint is violated by a metric of the runtime metrics and generate events when a constraint is violated by a metric of the runtime metrics.

Claims

1. A system for deploying and managing software services, comprising:

a computing environment that includes a plurality of virtualized and non-virtualized machines to which services and applications can be deployed;

a plurality of agents, wherein each agent resides on one of the plurality of virtualized and non-virtualized machines in the computing environment and can be used to manage the software processes and resources running in the computing environment and can also render the resources as a resource pool;

a rules engine that;

compares administrator defined constraints with runtime metrics, wherein a constraint of the administrator defined constraints is a user defined service level agreement (SLA) that is captured by a metric or state that is derived from meta data or metrics and the runtime metrics are provided to the rules engine by a monitor service;

generates events when a constraint is violated by a metric of the runtime metrics, each event generated by the rules engine carries with it information necessary to handle the event including the scope of a constraint failure that caused the event.

2. The system according to claim 1, wherein:

the rules engine resides in a controller and provides an OSGi service.

3. The system according to claim 1, wherein:

the rules engine utilizes a Drools Rules Engine model.

4. The system according to claim 1, wherein:

the rules engine is capable performing one of;

determining when action is necessary to satisfy an administrator defined constraint;

determining when deployment or un-deployment action is necessary; and

preparing context necessary for carrying out actions.

5. The system according to claim 1, wherein:

the runtime metrics are provided to the rules engine by a execute engine.

6. The system according to claim 1, further comprising:

a configuration service that is capable of configuring the rules engine.

7. The system according to claim 1, further comprising:

a monitor service that is capable of monitoring the rules engine.

8. The system according to claim 1, wherein:

the rules engine is associated with a trigger service that provides time based events.

9. The system according to claim 1, wherein:

the constraint is one of;

a service constraint;

a process constraint;

an observer constraint;

a event constraint; and

an action constraint.

10. The system according to claim 1, wherein:

the event generated by the rules engine has the same scope as the constraint that is associated with the event.

11. The system according to claim 1, wherein:

the rules engine manages a data structure that is a hierarchy of event states.

12. The system according to claim 1, wherein:

one of the plurality of agents is a Virtualized Agent.

13. A method for deploying and managing software services, comprising the steps of:

providing a computing environment that includes a plurality of virtualized and non-virtualized machines to which services and applications can be deployed;

providing an agent on each of the plurality of virtualized and non-virtualized machines, wherein each agent can be used to manage the software processes and resources running on the machine on which it resides and can also render the resources of the machine as a resource pool;

comparing administrator defined constraints with runtime metrics, wherein a constraint of the administrator defined constraints is a user defined service level agreement (SLA) that is captured by a metric or state that is derived from meta data or metrics and the runtime metrics are provided to the rules engine by a monitor service; and

generating events when a constraint is not satisfied by a metric of the runtime metrics, wherein each event generated by the rules engine carries with it information necessary to handle the event including the scope of a constraint failure that caused the event.

14. The method according to claim 13, further comprising at least one of:

determining when action is necessary to satisfy an administrator defined constraint;

determining when deployment or un-deployment action is necessary; and

preparing context necessary for carrying out actions.

15. The method according to claim 13, further comprising:

configuring the rules engine by a configuration service.

16. The method according to claim 13, further comprising:

monitoring the rules engine through a monitor service.

17. The method according to claim 13, further comprising:

associating with a trigger service that provides time based events.

18. The method according to claim 13, wherein:

the constraint is one of;

a service constraint;

a process constraint;

an observer constraint;

a event constraint; and

an action constraint.

19. The method according to claim 13, further comprising:

managing a data structure that is a hierarchy of event states.

20. A machine readable medium having instructions stored thereon that when executed cause a system to:

provide a computing environment that includes a plurality of virtualized and non-virtualized machines to which services and applications can be deployed;

provide an agent on each of the plurality of virtualized and non-virtualized machines, wherein each agent can be used to manage the software processes and resources running on the machine on which it resides and can also render the resources of the machine as a resource pool;

compare administrator defined constraints with runtime metrics, wherein a constraint of the administrator defined constraints is a user defined service level agreement (SLA) that is captured by a metric or state that is derived from metadata or metrics and the runtime metrics are provided to the rules engine by a monitor service; and

generate events when a constraint is not satisfied by a metric of the runtime metrics, wherein each event generated by the rules engine carries with it information necessary to handle the event including the scope of a constraint failure that caused the event.
