Abstract: A request to deploy a cloud-based application is received, and a unique identifier is assigned thereto. A server is selected and an agent program is installed thereon. A script queue stores a plurality of commands for the installation and configuration of the application, and the commands are sent to the agent for execution on the server, the execution of the commands causing installation and configuration of the application on the server.

Abstract: Transactions or operations associated with a received request are performed with a NoSQL database. A request ID is assigned to the request, an operation ID to the operation, and an entity ID to the entity associated with the operation. The entity is locked in the database, and the operation is performed. The database is unlocked, and a message is transmitted to a lock queue to release an entry therein associated with the request. If a second request attempt to lock the same entity while the first is concurrent, it requests that the lock queue inform it when the lock is released.

Abstract: Asynchronous functions in a programming workflow are executed by first storing a context structure comprising workflow-specific global variables and a global-context pointer variable that is a pointer to the context structure. When an asynchronous function is executed, the global-context pointer variable is stored in a local variable and, when the function completes, the global-context pointer variable is restored with the local variable.
