NQueue provides an enterprise level work scheduling and execution framework and toolset that contains no single point of failure. Using a farm of servers and a clustered SQL server backend, multiple NQueue windows services compete to evaluate configured schedules and execute work NQueue is a distributed system written in C# composed of the following high level components;
• Admin tool – A windows form application that enables add and delete operations against the various artefacts in a NQueue installation (jobs, schedules, host instances). This would typically be used to view or change the system configuration although it can also be used to immediately enqueue items of work for execution (during testing for example)
• NQueue Monitor website – A website allowing operations and support staff to view the progress of configured jobs. They may also pause or disable job instances from this tool.
• SQL Database – all state for the system is stored in a central (clustered) SQL database.
• Windows services – NQueue processing services running on any number of configured servers competing to evaluate job schedules and execute job code.
• Client API – A .net class library that users can consume/inherit from to allow their job code to interact with the framework.
• NQueueCmd – command line enqueuing of work to execute immediately.Read more: Codeplex
