Distributed scheduling systems for digital magazine

A method for distributing a plurality of tasks associated with presenting a digital magazine to a client device, the method comprising:

• associating, by a load balancing device, each of a plurality of tasks associated with the presenting the digital magazine to a corresponding one of a plurality of task service devices;
• assigning, by the plurality of task service devices, each of the plurality of tasks to a corresponding one of a plurality of execution devices;
• executing, by each of the plurality of execution devices, one or more assigned tasks of the plurality of tasks;
• generating, by each of the execution devices, an execution device heartbeat indicating that the execution device is operable for an assigned task;
• verifying, by the plurality of task service devices, statuses of the tasks assigned to the plurality of execution devices, verifying, by the plurality of task service devices, statuses of the tasks comprises:
• determining, by a task service device of the plurality of task service devices associated with a task, that an execution device assigned to execute the task is operable based on the execution device heartbeat associated with the execution device during an execution device heartbeat wait period;
• recording, by each of the task service devices, its status at a database during a service device heartbeat wait period;
• and
• determining, by each of the task service devices, statuses of other task service devices based on service device heartbeats associated with the other task service devices.

A non-transitory computer-readable storage medium storing executable computer program instructions for distributing a plurality of tasks associated with presenting a digital magazine to a client device, the computer program instructions when executed by a computer processor cause the computer processor to:

• associate, by a load balancing device, each of a plurality of tasks associated with the presenting the digital magazine to a corresponding one of a plurality of task service devices;
• assign, by the plurality of task service devices, each of the plurality of tasks to a corresponding one of a plurality of execution devices;
• execute, by each of the plurality of execution devices, one or more assigned tasks of the plurality of tasks;
• generate, by each of the execution devices, an execution device heartbeat indicating that the execution device is operable for an assigned task;
• verify, by the plurality of task service devices, statuses of the tasks assigned to the plurality of execution devices, verifying, by the plurality of task service devices, statuses of the tasks comprises:
• determine, by a task service device of the plurality of task service devices associated with a task, that an execution device assigned to execute the task is operable based on the execution device heartbeat associated with the execution device during an execution device heartbeat wait period;
• record, by each of the task service devices, its status at a database during a service device heartbeat wait period;
• and
• determine, by each of the task service devices, statuses of other task service devices based on service device heartbeats associated with the other task service devices.
