Abstract

Embodiments of the present invention provide an approach for managing distributed application relationships and dependencies, and migration of applications and components within the same or a disparate networked (e.g. cloud) service provider. An application dependency management program module (“ADM”), and cloud service migration management program module (“CSMM”) are provided. The ADM, manually or by deductive logic, discovers and manages relationships and dependencies of computer software applications underlying cloud services, state information of the respective computer software applications, as well as upstream and downstream network data connections. The CSMM comprises ensuring that applications are not migrated or modified in a manner that could affect overall service, ensuring that a migration is performed correctly, maintaining a list of service level requirements for monitoring whether those requirements are being met, and performing application migration.

Claims

1. A computer implemented method for managing application migration in a networked computing environment, the method comprising the steps of:

generating a list of relationships and dependencies, via a computer implemented deductive logic method, associated with a first networked computing service and one or more current computer software applications utilized by the first networked computing service that is within a local cloud service provider infrastructure, wherein the list includes upstream and downstream network data connections of the first networked computing service;

storing the list on an electronic storage device;

determining an availability of one or more replacement computer software applications for the one or more current computer software applications that are utilized by the first networked computing service, wherein the one or more replacement computer software applications having at least the functionality as the one or more computer software applications;

determining an impact on service levels and performance of the first networked computing service that would result from at least one of an inter-cloud migration of the one or more current computer software applications to a remote cloud service provider infrastructure and an intra-cloud migration of the one or more current computer software applications within the local cloud service provider infrastructure, wherein the one or more current computer software applications migrate from the first networked computing service to a second networked computing service, based upon the list and the availability of the one or more replacement computer software applications;

migrating the one or more current computer software applications from the first networked computing service to the second networked computing service; and

receiving at least the functionality from the one or more replacement software applications, wherein the migration of the one or more current computer software applications is reversible if an actual impact of the migration is greater than the determined impact.

2. The method of claim 1, wherein the step of generating the list further comprises an administrator defining the relationships and dependencies of the one or more current computer software applications, and the upstream and downstream network data connections of the first networked computing service.

3. The method of claim 1, wherein the step of generating the list further comprises logically deducing the application relationships and dependencies of the one or more current computer software applications, and the upstream and downstream network data connections of the first networked computing service.

4. The method of claim 1, wherein the step of determining the availability is performed by an application dependency management program module that utilizes data which include at least one of the following:

ability of networked computer servers to execute the one or more current software applications, measured performance of the functionality of the one or more replacement computer software applications, relationships and dependencies of the one or more current computer software applications, and the upstream and downstream network data connections of the first networked computing service.

5. The method of claim 1, wherein the step of determining the impact is performed prior to a migration of the one or more current computer software applications, wherein the list of relationships and dependencies is used to determine an overall performance impact on the first networked computing service, and determine an impact on fulfilling requirements of a service level agreement.

6. The method of claim 5, wherein a service migration management program module is signaled whether to migrate the one or more current computer software applications based on the determined impact.

7. The method of claim 6, wherein the impact further indicates whether the one or more current computer software applications can be migrated as a group, as a subset of a group, in whole, in parts, or not at all.

8. A system for managing application migration in a networked computing environment, the system comprising:

a bus;

a processor coupled to a bus;

a memory medium coupled to the bus, the memory medium comprising instructions to;

generate a list of relationships and dependencies, via a computer implemented deductive logic method, associated with a first networked computing service and one or more current computer software applications utilized by the first networked computing service that is within a local cloud service provider infrastructure, wherein the list includes upstream and downstream network data connections of the first networked computing service;

store the list on an electronic storage device;

determine an availability of one or more replacement computer software applications for the one or more current computer software applications that are utilized by the first networked computing service, wherein the one or more replacement computer software applications having at least the functionality of the one or more computer software applications;

determine an impact on service levels and performance of the first networked computing service that would result from at least one of an inter-cloud migration of the one or more current computer software applications to a remote cloud service provider infrastructure and an intra-cloud migration of the one or more current computer software applications within the local cloud service provider infrastructure, wherein the one or more current computer software applications migrate from the first networked computing service to a second networked computing service, based upon the list and the availability of the one or more replacement computer software applications; and

migrate the one or more current computer software applications from the first networked computing service to the second networked computing service such that at least the functionality from the one or more replacement software applications is received, wherein the migration of the one or more current computer software applications is reversible if an actual impact of the migration is greater than the determined impact.
