Dynamic allocation of messaging resources in software as a service messaging platform

A system, comprising:

• a memory;
• and
• a processing device, coupled to the memory, the processing device configured to:
• generate a hierarchical data structure comprising a plurality of levels, wherein a first level of the plurality of levels comprises a first plurality of nodes, each node of the first plurality of nodes associated with a respective sub-account of a specified parent account of a messaging platform, wherein a second level of the plurality of levels comprises a second plurality of nodes, each node of the second plurality of nodes associated with a respective level of service supported by the messaging platform, and wherein a third level of the plurality of levels comprises a third plurality of nodes, each node of the third plurality of nodes associated with a respective destination;
• traverse the hierarchical data structure, by identifying, for each node of the hierarchical data structure, a respective plurality of child nodes;
• allocate, to each node of the plurality of child nodes, a respective share of a messaging resource quota associated with its parent node;
• associate, with each terminal node of a plurality of terminal nodes of the hierarchical data structure, a respective message queue of a plurality of message queues;
• allocate, to each message queue of the plurality of message queues, a respective messaging resource quota associated with a corresponding terminal node;
• receive, from a user associated with a specified sub-account, a request to forward, to a specified destination, a message associated with a specified level of service;
• identify, among the plurality of message queues, a message queue associated with the specified level of service and the specified sub-account;
• and
• queue the message into the identified message queue.

A non-transitory computer-readable storage medium comprising executable instructions that, responsive to execution by a processing device, cause the processing device to:

• generate a hierarchical data structure comprising a plurality of levels, wherein a first level of the plurality of levels comprises a first plurality of nodes, each node of the first plurality of nodes associated with a respective sub-account of a specified parent account of a messaging platform, wherein a second level of the plurality of levels comprises a second plurality of nodes, each node of the second plurality of nodes associated with a respective level of service supported by the messaging platform, and wherein a third level of the plurality of levels comprises a third plurality of nodes, each node of the third plurality of nodes associated with a respective destination;
• traverse the hierarchical data structure, by identifying, for each node of the hierarchical data structure, a respective plurality of child nodes;
• allocate, to each node of the plurality of child nodes, a respective share of a messaging resource quota associated with its parent node;
• associate, with each terminal node of a plurality of terminal nodes of the hierarchical data structure, a respective message queue of a plurality of message queues;
• allocate, to each message queue of the plurality of message queues, a respective messaging resource quota associated with a corresponding terminal node;
• receive, from a user associated with a specified sub-account, a request to forward, to a specified destination, a message associated with a specified level of service;
• identify, among the plurality of message queues, a message queue associated with the specified level of service and the specified sub-account;
• and
• queue the message into the identified message queue.
