In an application execution system having a plurality of application servers, each application server stores a plurality of applications, and has computational resources for executing applications in response to received requests. Each application server also includes instructions for loading a respective application into volatile storage and executing the application in response to a request from a client, and for returning a result. A generic application instance may be cloned, creating a pool of generic application instance clones that can be loaded with code for a requested application to produce an application instance. The application instance can then be stored in a cache to be used for a future application request.

Application hosting in a distributed application execution system

A coupling including a first elongate member and a second elongate member. The first elongate member includes a first tube and a first magnet. The first tube has a first end and a second end. The first magnet secures to the first end of the first tube. The second elongate member includes a second tube and a second magnet. The second tube has a first end and a second end. The second magnet secures to the first end of the second tube. The first and second magnets are cooperatively configured to attract one another and secure the first end of the first tube to the first end of the second tube.

Coupling for a drinking straw

In an application execution system having a plurality of application servers and an application master in an application execution system, the application master stores a plurality of applications, including a respective application, in a library for distribution among the application servers, adds a first instance of the respective application from the library to a respective application server for execution, and obtains usage information of one or more applications added to the application servers. In accordance with the usage information, the application master performs one of a predefined set of actions that includes: adding a second instance of the respective application to the plurality of application servers; and removing the first instance of the respective application from the respective application server.

In an application execution system having a plurality of application servers, each application server stores a plurality of applications, and has computational resources for executing applications in response to received requests. Each application server also includes instructions for loading a respective application into volatile storage and executing the application in response to a request from a client, and for returning a result. In addition, each application server includes instructions for conditionally terminating execution of the respective application prior to returning the result if the respective application violates any execution restriction. The execution restrictions may include: a response time limit; an average response time limit over multiple executions of the application; a volatile memory usage limit; a restriction on using non-volatile storage of the application server; and a requirement limiting where state information is stored. The execution restrictions in aggregate maintain scalability of the application execution system.

Application server scalability through runtime restrictions enforcement in a distributed application execution system

In an application execution system having a plurality of application servers, each application server includes non-volatile storage for storing a plurality of applications, volatile storage and computational resources for executing applications in response to requests received by the application execution system and for returning results to the requestors. In addition, each application server includes instructions for conditionally terminating execution of the respective application prior to returning the result if the respective application violates any of a plurality of execution restrictions. The execution restrictions in aggregate maintain scalability of the application execution system with respect to at least one or more of the following limits: number of applications that can be executed and number of requests that can be processed per period of time.

In a distributed application execution system having an application master and a plurality of application servers, each application server includes one or more processors and memory storing one or more programs. The one of more programs include instructions for storing in non-volatile storage a plurality of applications distributed to the application server by the application master, for loading into volatile storage and executing a respective application in response to a received request, and for returning a result to the request. In addition, the one of more programs include instructions for conditionally retaining the respective application in volatile storage, for responding to a future request, when criteria, including at least predefined usage level criteria, are met by the respective application, and otherwise removing the respective application from volatile storage upon returning the result to the request.
