Context aware dynamic composition of migration plans to cloud

1. A computer readable storage medium storing a program of instructions executable by a machine to perform a method of providing context aware dynamic composition of migration plans, the method comprising:

receiving a request to migrate at least one of application and computer system image from a source environment;

identifying a target environment and associated configuration to define target definition;

defining one or more contextual actions comprising a sequence of migration steps;

allocating resources associated with the source environment and a schedule for triggering the one or more contextual actions;

selecting automatically one or more migration techniques to use to implement the one or more contextual actions based on current context of the source environment and the target environment;

monitoring an execution of migration performed according to the allocating and the selecting;

responsive to detecting one or more exceptions in the execution of migration, regenerating a migration plan, the one or more exceptions comprising a component defined in the target definition missing from the target environment, and the regenerating the migration plan to include a contextual action comprising installing the missing component in the target environment; and

automatically generating a migration template comprising learned patterns associated with a particular context learned based on semi-supervised machine learning observing historical data and user input,

wherein the template captures one or more steps that apply in a given context, which can be reused in future;

wherein the semi-supervised machine learning involves interactively querying a user to obtain outputs at new data points.

2. The computer readable storage medium of claim 1 , wherein the regenerating a migration plan comprises repeating the allocating and the selecting.

3. The computer readable storage medium of claim 1 , wherein the regenerating a migration plan comprises repeating the defining, the allocating and the selecting.

4. The computer readable storage medium of claim 1 , wherein the one or more exceptions comprises a change in one or more of the source environment and the target environment during the migration.

5. The computer readable storage medium of claim 1 , further comprising continuing to monitor one or more of the source environment and the target environment for changes, after completing of the migration.

6. The computer readable storage medium of claim 5 , further comprising responsive to detecting one or more of the changes, performing the regenerating of the migration plan based on detected one or more changes.

7. The computer readable storage medium of claim 1 , further comprising automatically generating a script comprising the sequence of migration steps and the one or more migration techniques used in implementing the sequence of migration steps.

8. The computer readable storage medium of claim 7 , further comprising automatically executing the script.

9. The computer readable storage medium of claim 7 , wherein responsive to detecting one or more exceptions in the execution of migration, the regenerating a migration plan comprises changing a migration technique selected from at least one of physical migration, image migration, application/workload migration, and data migration.

10. A system of providing context aware dynamic composition of migration plans, comprising:

a processor; and

a storage device,

the processor operable to receive a request to migrate at least one of application and computer system image from a source environment,

the processor further operable to identify a target environment and associated configuration to define a target definition,

the processor further operable to define one or more contextual actions comprising a sequence of migration steps,

the processor further operable to allocate resources associated with the source environment and a schedule for triggering the one or more contextual actions,

the processor further operable to select automatically one or more migration techniques to use to implement the one or more contextual actions based on current context of the source environment and the target environment,

the processor further operable to generate a script comprising the sequence of migration steps and the one or more migration techniques used in implementing the sequence of migration steps, and store the script on the storage device,

the processor further operable to monitor an execution of migration performed according to the allocating and the selecting,

responsive to detecting one or more exceptions in the execution of migration, the processor further operable to regenerate a migration plan, the one or more exceptions comprising a component defined in the target definition missing from the target environment, and the processor regenerating the migration plan to include a contextual action comprising installing the missing component, and

the processor further operable to automatically generate a migration template comprising learned patterns associated with a particular context learned based on semi-supervised machine learning observing historical data and user input,

wherein the template captures one or more steps that apply in a given context, which can be reused in future,

wherein the semi-supervised machine learning involves interactively querying a user to obtain outputs at new data points.

11. The system of claim 10 , wherein the processor is further operable to regenerate a migration plan by repeating at least one of the defining, the allocating and the selecting.

12. The system of claim 10 , wherein the processor regenerates the migration plan by changing a migration technique selected from at least one of physical migration, image migration, application/workload migration, and data migration.
