Abstract

A method and system for migration of multi-tier virtual application across different clouds hypervisor platforms. The principal object of the embodiment is to provide migration of multi-tier virtual application from one vendor to another vendor cloud platforms. Another object of the embodiment is to convert entire multi-tier virtual application of a source vendor cloud platforms, along with the virtual machines, configuration and properties into a format suitable for a destination vendor cloud platforms. Another object of the embodiment is to verify the migrated application after completion of conversion and migration.

Claims

1. A method for migrating at least one application from a source cloud to a target cloud using a migration server, said method comprising:

identifying a source application package by said source cloud, wherein said source application package comprises of all virtual machines and all application level configurations associated with said migrating application;

exporting to a logical container the source application package by said source cloud to said migration server;

extracting at least application configurations from the exported application by said migration server;

converting, by a configuration convertor, the source package application into a target application package compatible with target cloud by said migration server, wherein said target application package is constructed using the extracted application configurations in the target cloud platform;

sending the target application package to the target cloud by said migration server;

launching said target application by said migration server, wherein said launching is configured to be performed in at least one of a given order, a different order and simultaneously; and

verifying said migrated target application by said migration server, wherein said verifying is configured to comprise at least matching at least a corresponding property in said target cloud with said source cloud, by a mapping table in said migration server.

2. The method as in claim 1, further comprising migrating virtual machines by a virtual machine migration tool.

3. The method as in claim 1, said method further comprising:

migrating virtual machines by at least a virtual machine migration tool;

finding equivalence of Application Properties and Configurations format elements between source and target clouds by at least a mapping table; and

constructing said source applications package into a target application package compatible with said target cloud by at least a conversion tool.

4. The method as in claim 1, said method further comprising adapting said server to be deployed independently of said source cloud and said target cloud.

5. A system for migrating at least one application from a source cloud to a target cloud using a migration server, said system configured for:

identifying a source application package by said source cloud, wherein said source application package comprises of all virtual machines and all application level configurations associated with said migrating application;

exporting to a logical container the source application package by said source cloud to said migration server;

extracting at least application configurations from the exported application by said migration server;

converting, by a configuration convertor, the source package application into a target application package compatible with target cloud by said migration server, wherein said target application package is constructed using the extracted application properties in the target cloud platform;

sending the target application package to the target cloud by said migration server;

launching said target application by said migration server, wherein said launching is configured to be performed in at least one of a given order, a different order and simultaneously; and

verifying said migrated target application by said migration server, wherein said verifying is configured to comprise at least matching at least a corresponding property in said target cloud with said source cloud, by a mapping table in said migration server.

6. The system as in claim 5, said system comprising:

at least a hardware processor; and

at least a non-transitory storage medium having a computer program code, wherein said computer program code causes said hardware processor to;

migrate virtual machines by at least a virtual machine migration tool;

find equivalence of Application Properties and Configurations format elements between source and target clouds by at least a mapping table; and

construct said source applications package into a target application package compatible with said target cloud by at least a conversion tool.

7. The system as in claim 5, wherein said server is adapted to be deployed independently of said source cloud and said target cloud.

8. The system as in claim 5, wherein said migration server further comprises a virtual machine migration tool for migrating virtual machines.
