Abstract

Data-persisting temporary virtual machine environments are described. A computing system enables a user to access a virtual machine and a virtual data store in a temporary virtual machine environment in response to receiving a user request to access the temporary virtual machine environment. The computing system stores data as virtual data store data in the virtual data store in response to receiving the data from the user. The computing system creates a copy of the virtual data store data if all users are signed off from use of the temporary virtual machine environment. The computing system deletes the virtual machine and the virtual data store. The computing system receives a request by a specific user to access the temporary virtual machine environment, and enables the specific user to access a recreated virtual machine and the copy of the virtual data store data.

Claims

1. A system for data-persisting temporary virtual machine environments, the system comprising:

one or more processors; and

a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to;

enable a user to access a virtual machine and a virtual data store in a temporary virtual machine environment in response to receiving a user request to access the temporary virtual machine environment;

store data as virtual data store data in the virtual data store in response to receiving the data from the user;

create a copy of the virtual data store data in response to a determination that all users are signed off from use of the temporary virtual machine environment, the determination being made in response to an expiration of a deadline for the temporary virtual machine environment;

delete the virtual machine and the virtual data store;

receive a request by a specific user to access the temporary virtual machine environment; and

enable the specific user to access a recreated virtual machine and the copy of the virtual data store data.

2. The system of claim 1, wherein the plurality of instructions to enable the user to access the virtual machine and the virtual data store in the temporary virtual machine environment further cause the one or more processors to:

determine whether the temporary virtual machine environment is already created for a set of users that comprises the user;

create the virtual machine and the virtual data store in the temporary virtual machine environment in response to a determination that the temporary virtual machine is not already created for the set of users that comprises the user; and

direct the user to access the virtual machine and the virtual data store in the temporary virtual machine environment in response to a determination that the temporary virtual machine is already created for the set of users that comprises the user.

3. The system of claim 1, wherein the plurality of instructions to create the copy of the virtual data store data further cause the one or more processors to apply a schema update to the data prior to creating the copy of the data.

4. The system of claim 1, wherein the plurality of instructions to create the copy of the virtual data store data further cause the one or more processors to:

identify another data store that stores other data that has a dependency relationship with the data in the virtual data store data;

create a copy of the other data in the other data store; and

tag at least one of the copy of the virtual data store data and the copy of the other data with information that identifies the dependency relationship.

5. The system of claim 1, wherein the plurality of instructions to enable the specific user to access the recreated virtual machine and the copy of the virtual data store data further cause the one or more processors to:

identify other data that has a dependency relationship with the copy of the virtual data store data; and

enable the specific user to access the other data stored in another virtual data store via another virtual machine.

6. The system of claim 1, wherein the plurality of instructions to enable the specific user to access the recreated virtual machine and the copy of the virtual data store data further cause the one or more processors to:

determine whether the temporary virtual machine environment that includes the recreated virtual machine and a recreated virtual data store has been created for a set of users that includes the specific user;

create the temporary virtual machine environment that includes the recreated virtual machine and the recreated virtual data store in response to a determination that the temporary virtual machine is not already created for the set of users that include the specific user; and

direct the user to access the recreated virtual machine and the recreated virtual data store in the temporary virtual machine environment in response to a determination that the temporary virtual machine is already created for the set of users that includes the specific user.

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

enable a user to access a virtual machine and a virtual data store in a temporary virtual machine environment in response to receiving a user request to access the temporary virtual machine environment;

store data as virtual data store data in the virtual data store in response to receiving the data from the user;

create a copy of the virtual data store data in response to a determination that all users are signed off from use of the temporary virtual machine environment, the determination being made in response to an expiration of a deadline for the temporary virtual machine environment;

delete the virtual machine and the virtual data store;

receive a request by a specific user to access the temporary virtual machine environment; and

enable the specific user to access a recreated virtual machine and the copy of the virtual data store data.

8. The computer program product of claim 7, wherein the instructions to enable the user to access the virtual machine and the virtual data store in the temporary virtual machine environment comprise further instructions to:

determine whether the temporary virtual machine environment is already created for a set of users that comprises the user;

create the virtual machine and the virtual data store in the temporary virtual machine environment in response to a determination that the temporary virtual machine is not already created for the set of users that comprises the user; and

direct the user to access the virtual machine and the virtual data store in the temporary virtual machine environment in response to a determination that the temporary virtual machine is already created for the set of users that comprises the user.

9. The computer program product of claim 7, wherein the instructions to create the copy of the data in the virtual data store comprise further instructions to apply a schema update to the data prior to creating the copy of the data.

10. The computer program product of claim 7, wherein the instructions to create the copy of the virtual data store data comprise further instructions to:

identify another data store that stores other data that has a dependency relationship with the data in the copy of the virtual data store data;

create a copy of the other data in the other data store; and

tag at least one of the copy of the virtual data store data and the copy of the other data with information that identifies the dependency relationship.

11. The computer program product of claim 7, wherein the instructions to enable the specific user to access the recreated virtual machine and the copy of the virtual data store data further comprise instructions to:

identify other data that has a dependency relationship with the data in the copy of the virtual data store data; and
