Abstract

Disclosed are systems and methods relating to the deployment of an application. A plurality of nodes in one or more clusters of nodes may be identified. Inventory information for each of the plurality of nodes may be retrieved. The inventory information may provide configuration and state information associated with each node. For example, the inventory information retrieved from the plurality of nodes may include an internet protocol address or a hostname associated with each the plurality of nodes, and a version of software installed on each of the plurality of nodes. An order for deploying the software application may be determined based on the retrieved inventory information. The order may identify a sequence in which the software application is deployed to at least one of the plurality of nodes. The software application may be deployed to at least one of the plurality of nodes based on the determined order.

Claims

1. A method for deploying a software application to a plurality of nodes, the method comprising:

identifying the plurality of nodes in one or more clusters of nodes, the one or more clusters of nodes functioning as a single unit providing failover and load balancing for execution of a software application;

retrieving inventory information for each node of the plurality of nodes, the inventory information providing configuration and state information associated with each node, wherein the state information specifies whether each node is an active node or a passive node in a failover and load balancing cluster, wherein each active node is being used to provide services associated with the application and each passive node is not being used to provide services, each passive node being available to provide services associated with the application if an active node fails or is overburdened;

determining an order of the plurality of nodes for deploying the software application by applying one or more rules associated with deploying the software application and retrieved from a rules engine storing a plurality of rules to the retrieved inventory information, the order identifying a sequence in which the software application is deployed to the plurality of nodes; and

deploying the software application to the plurality of nodes based on the determined order.

2. The method of claim 1, wherein the order is compatible with failover and load balancing capabilities of the one or more clusters of nodes.

3. The method of claim 1, wherein the one or more rules are user-defined rules.

4. The method of claim 1 further comprising generating a graphical representation of the one or more clusters of nodes based on the inventory information retrieved from the plurality of nodes.

5. The method of claim 4, wherein the graphical representation displays active nodes and passive nodes in the one or more clusters of nodes.

6. The method of claim 1 further comprising generating a warning that indicates that at least one node of the plurality of nodes has a version of the software application that is non-compliant with software installed on other nodes in the one or more clusters of nodes.

7. The method of claim 1, wherein the order is determined based, at least in part, on a dependency between the software application that is being deployed and another software application.

8. The method of claim 1, wherein the one or more nodes are identified based on a virtual internet protocol address associated with the one or more clusters.

9. The method of claim 1, wherein the inventory information retrieved from the plurality of nodes includes an internet protocol address or a hostname associated with each node of the plurality of nodes.

10. The method of claim 1, wherein a node is a physical node in a communications network that has an associated internet protocol address.

11. The method of claim 1, wherein inventory information associated with each node of the plurality of nodes is retrieved from at least one load balancer.

12. A computer program product comprising computer-readable program code stored in a non-transitory computer-readable medium to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions to:

identify a plurality of nodes in one or more clusters of nodes, the one or more clusters of nodes functioning as a single unit providing failover and load balancing for execution of a software application;

retrieve inventory information for each node of the plurality of nodes, the inventory information providing configuration and state information associated with each node, wherein the state information specifies whether each node is an active node or a passive node in a failover and load balancing cluster, wherein each active node is being used to provide services associated with the application and each passive node is not being used to provide services, each passive node being available to provide services associated with the application if an active node fails or is overburdened;

determine an order of the plurality of nodes for deploying the software application by applying one or more rules associated with deploying the software application and retrieved from a rules engine storing a plurality of rules to the retrieved inventory information, the order identifying a sequence in which the software application is deployed to the plurality of nodes; and

deploy the software application to the plurality of nodes based on the determined order.

13. The computer program product of claim 12, wherein the order is compatible with failover and load balancing capabilities of the one or more clusters of nodes.

14. The computer program product of claim 12, wherein the steps further comprise:

generating a graphical representation of the one or more clusters of nodes based on the inventory information retrieved from the plurality of nodes, wherein the graphical representation displays active nodes and passive nodes in the one or more clusters of nodes.

15. The computer program product of claim 12, wherein the inventory information retrieved from the plurality of nodes includes an internet protocol address or a hostname associated with each node of the plurality of nodes.

16. The computer program product of claim 12, wherein inventory information associated with each node of the plurality of nodes is retrieved from at least one load balancer.

17. A system for deploying a software application to a plurality of nodes comprising:

a processor; and

one or more stored sequences of instructions which, when executed by the processor, cause the processor to;

identify the plurality of nodes in one or more clusters of nodes, the one or more clusters of nodes functioning as a single unit providing failover and load balancing for execution of a software application;

retrieve inventory information for each node of the plurality of nodes, the inventory information providing configuration and state information associated with each node, wherein the state information specifies whether each node is an active node or a passive node in a failover and load balancing cluster, wherein each active node is being used to provide services associated with the application and each passive node is not being used to provide services, each passive node being available to provide services associated with the application if an active node fails or is overburdened;

determine an order of the plurality of nodes for deploying the software application by applying one or more rules associated with deploying the software application and retrieved from a rules engine storing a plurality of rules to the retrieved inventory information, the order identifying a sequence in which the software application is deployed to the plurality of nodes; and

deploy the software application to the plurality of nodes based on the determined order.

18. The system of claim 17, wherein the order is compatible with failover and load balancing capabilities of the one or more clusters of nodes.

19. The system of claim 17, wherein the steps further comprise:

generating a graphical representation of the one or more clusters of nodes based on the inventory information retrieved from the plurality of nodes, wherein the graphical representation displays active nodes and passive nodes in the one or more clusters of nodes.

20. The system of claim 17, wherein the inventory information retrieved from the plurality of nodes includes an internet protocol address or a hostname associated with each node of the plurality of nodes.
