Apparatus and method for virtual desktop service

Abstract: Disclosed herein are a method and architecture capable of efficiently providing virtual desktop service. A service architecture for virtual desktop service according to the present invention includes a connection broker configured to perform authentication, manage virtual machines, and perform a server monitoring and protocol coordination function, a resource pool configured to manage software resources that are delivered to a specific virtual machine in a streaming form on a specific time in order to provide on-demand virtual desktop service and are executed on the specific virtual machine and to provide provision information about the managed software resources in response to a request from the connection broker, and a virtual machine infrastructure configured to support hardware resources, generate virtual machines in which the software of a user terminal is executed, and provide the generated virtual machine as virtual desktops.

Virtual desktop service apparatus and method

Abstract: Disclosed is a virtual desktop service method. The virtual desktop service method includes configuring and measuring users and resources according to predetermined criteria, copying operating system files and data files to be provided to the users before use request, receiving request to use a virtual machine from any one of the users and performing user authentication and work approval, and providing an operating system file and a data file of the any one of the users, among the copied operating system files and data files, to the any one of the users according to the use request to transmit a virtual desktop environment. Consequently, the virtual desktop service method performs a service to provide a virtual machine to a user in real time.

Method and system for providing server virtual machine for real-time virtual desktop service, and server device supporting the same

Abstract: Provided is a virtual desktop service, and disclosed is a system for providing a server virtual machine, including: a client configured to receive allocation of a virtual machine for using a virtual desktop service; a connection broker configured to control a type of virtual machine to be allocated to be classified according to user terminal registration information of the client, any one operation server to be selected among a plurality of operation servers, and the virtual machine to be allocated; the plurality of operation servers configured to provide the client with a virtual machine under a control of the connection broker; and a shared storage configured to store data related to the client for providing the virtual machine, and provide the stored data to the operation servers, a method of providing a server virtual machine, and a server device supporting the same.

Apparatus and method for providing virtual machine image file

Abstract: Provided is a method of providing a virtual machine image file in a cloud computing-based virtual desktop infrastructure. This method includes moving a golden image, an initial image provided from a shared storage, to a virtual machine driving server, converting the golden image into an image of a copy-on-write file format, and storing the same in a cache; allocating the converted virtual machine image to a virtual machine, and storing images of each virtual machine in the shared storage and managing the same to recover a virtual desktop when a disaster occurs. The method includes generating only data changed by the virtual machine, as a virtual machine image file, and managing the same, and hierarchically configuring a virtual machine image file based on a base image and storing the same in a cache memory in order to increase a loading rate of the virtual machine image file including the base image-based virtual machine image file.

Processing event messages for user requests to execute program code

Abstract: A service manages a plurality of virtual machine instances for low latency execution of user codes. The service can provide the capability to execute user code in response to events triggered on an auxillary service to provide implicit and automatic rate matching and scaling between events being triggered on the auxiliary service and the corresponding execution of user code on various virtual machine instances. An auxiliary service may be configured as an event triggering service to detect events and generate event messages for execution of the user codes. The service can request, receive, or poll for event messages directly from the auxiliary service or via an intermediary message service. Event messages can be rapidly converted to requests to execute user code on the service. The time from processing the event message to initiating a request to begin code execution is less than a predetermined duration, for example, 100 ms.

Security protocols for low latency execution of program code

Abstract: A system for providing security mechanisms for secure execution of program code is described. The system may be configured to maintain a plurality of virtual machine instances. The system may be further configured to receive a request to execute a program code and allocate computing resources for executing the program code on one of the virtual machine instances. One mechanism involves executing program code according to a user-specified security policy. Another mechanism involves executing program code that may be configured to communicate or interface with an auxiliary service. Another mechanism involves splitting and executing program code in a plurality of portions, where some portions of the program code are executed in association with a first level of trust and some portions of the program code are executed with different levels of trust.

Asynchronous task management in an on-demand network code execution environment

Abstract: Systems and methods are described for managing asynchronous code executions in an on-demand code execution system or other distributed code execution environment, in which multiple execution environments, such as virtual machine instances, can be used to enable rapid execution of user-submitted code. When asynchronous executions occur, a first execution may call a second execution, but not immediately need the second execution to complete. To efficiently allocate computing resources, this disclosure enables the second execution to be scheduled accordingly to a state of the on-demand code execution system, while still ensuring the second execution completes prior to the time required by the first execution. Scheduling of executions can, for example, enable more efficient load balancing on the on-demand code execution system.

Threading as a service

Abstract: A service manages a plurality of virtual machine instances for low latency execution of user codes. The plurality of virtual machine instances can be configured based on a predetermined set of configurations. One or more containers may be created within the virtual machine instances. In response to a request to execute user code, the service identifies a pre-configured virtual machine instance suitable for executing the user code. The service can allocate the identified virtual machine instance to the user, create a new container within an instance already allocated to the user, or re-use a container already created for execution of the user code. When the user code has not been activated for a time-out period, the service can invalidate allocation of the virtual machine instance destroy the container. The time from receiving the request to beginning code execution is less than a predetermined duration, for example, 100 ms.

Endpoint management system providing an application programming interface proxy service

Abstract: An endpoint management and proxy system is described, by which users can manage and enable exposure of application programming interfaces ("APIs") usable to cause execution of program code on a remote or third party system. Systems and methods are disclosed which facilitate the handling of user requests to perform certain tasks on remote systems. The endpoint management system allows the application developer to define and specify a first proxy API which maps to a second API associated with the remote system. The endpoint proxy system receives requests to execute the proxy API, determines the API mapping, and sends one or more backend API requests to execute program codes by the associated remote systems. Responses from the remote systems are received by the endpoint proxy system which parses and/or transforms the results associated with the response and generates an output result for response back to the user computing systems.
