Deployment and management of virtual containers
A system virtualizes applications on a managed endpoint using containers. A managed endpoint receives a virtualized container from an IT automation appliance. The virtualized container includes an application and a virtualization module. The virtualization module includes computer program instructions for virtualizing the application. An operating system API call made by the application during execution is intercepted, and a portion of the computer program instructions are executed based on the operating system API call. The computer program instructions modify the behavior of the application to effect the file and data virtualization of the application. A virtualized container can be deployed and updated from an IT automation appliance along with an agent to support the deployment and updating of the virtualized container.
1. A method for virtualizing applications on a computer using virtual containers, the method comprising:
receiving, at a managed endpoint, a virtual container from a remote computer, the virtual container including an application and computer program instructions for virtualizing the application;
storing the virtual container at the managed endpoint;
determining that the application has started executing at the managed endpoint;
creating a user environment for a user of the application;
monitoring, by the computer program instructions for virtualizing the application, the application for an operating system application program interface (API) call to write a file to a file system of the managed endpoint, the file system located outside of the virtual container;
determining whether to allow the operating system API call to write the file to the file system to proceed, and in response to the determination:
blocking, by the computer program instructions for virtualizing the application, the operating system API call to write the file to the file system;
modifying a filename parameter of the operating system API call to redirect the file to the virtual container;
modifying the user environment to reflect redirection of the file to the virtual container;
writing the file to a location within the virtual container; and
executing the computer program instructions for virtualizing the application that are configured to modify a behavior of the application including:
isolating the application from other applications executing at the managed endpoint; and
isolating data associated with the application from other data stored at the managed endpoint.
2. The method of claim 1 , wherein the computer program instructions for virtualizing the application are further configured to prevent the application from accessing malware.
3. The method of claim 1 , further comprising re-flashing the virtual container to return the virtual container to its initial state.
4. The method of claim 1 , further comprising:
determining whether the application executing at the managed endpoint is part of the virtual container; and
hooking the computer program instructions for virtualizing the application into an appropriate operating system API call in response to determining that the application is part of the virtual container.
5. A system for virtualizing applications on a computer using virtual containers, the system comprising:
a processor;
a non-transitory, computer-readable medium communicatively coupled to the processor; and
computer program instructions stored on the computer-readable medium, the computer program instructions configured to, when executed by the processor, cause the processor to:
receive a virtual container at a managed endpoint from a remote computer and store the virtual container at the managed endpoint, the virtual container including an application and computer program instructions configured for virtualizing the application;
determine that the application has started executing at the managed endpoint;
create a user environment for a user of the application;
monitor the application for an operating system application program interface (API) call to write a file to a file system of the managed endpoint, the file system located outside of the virtual container;
determine whether to allow the operating system API call to write the file to the file system to proceed, and in response to the determination:
block the operating system API call to write the file to the file system;
modify a filename parameter of the operating system API call to redirect the file to the virtual container;
modify the user environment to reflect redirection of the file to the virtual container;
write the file to a location within the virtual container; and
execute the computer program instructions for virtualizing the application that are configured to modify a behavior of the application including:
isolating the application from other applications executing at the managed endpoint; and
isolating data associated with the application from other data stored at the managed endpoint.
6. The system of claim 5 , wherein the computer program instructions for virtualizing the application are further configured to, when executed by the processor, prevent the application from accessing malware.
7. The system of claim 5 , wherein the computer program instructions are further configured to, when executed by the processor, cause the processor to re-flash the virtual container to return the virtual container to its initial state.
8. The system of claim 5 , wherein the computer program instructions are further configured to, when executed by the processor, cause the processor to:
determine whether the application is part of the virtual container; and
hook the computer program instructions for virtualizing the application into appropriate operating system API calls in response to determining that the application is part of the virtual container.
9. A non-transitory, computer-readable medium storing computer program instructions that, when executed by a processor, cause the processor to:
receive, at a managed endpoint, a virtual container from a remote computer, the virtual container including an application and computer program instructions for virtualizing the application;
store the virtual container at the managed endpoint;
determine that the application has started executing at the managed endpoint;
create a user environment for a user of the application;
monitor the application for an operating system application program interface (API) call to write a file to a file system of the managed endpoint, the file system located outside of the virtual container;
determine whether to allow the operating system API call to write the file to the file system to proceed, and in response to the determination:
block the operating system API call to write the file to the file system;
modify a filename parameter of the operating system API call to redirect the file to the virtual container;
modify the user environment to reflect redirection of the file to the virtual container;
write the file to a location within the virtual container; and
execute the computer program instructions for virtualizing the application that are configured to modify a behavior of the application including:
isolating the application from other applications executing at the managed endpoint; and
isolating data associated with the application from other data stored at the managed endpoint.
10. The computer-readable medium of claim 9 , wherein the computer program instructions for virtualizing the application are further configured to, when executed by the processor, cause the processor to prevent the application from accessing malware.
11. The computer-readable medium of claim 9 , wherein the computer program instructions are further configured to, when executed by the processor, cause the processor to re-flash the virtual container to return the virtual container to its initial state.
12. The computer-readable medium of claim 9 , wherein the computer program instructions are further configured to, when executed by the processor, cause the processor to:
determine that the application is part of a virtual container; and
hook the computer program instructions for virtualizing the application into an appropriate operating system API call in response to determining that the application is part of the virtual container.
