Synchronized cache of an operational state of distributed software system

A controller device comprising:

• one or more network interfaces communicatively coupled to one or more devices of a virtual network;
• and
• a processor configured to:
• coordinate execution of a set of two or more related processes executed by respective devices in the virtual network, wherein coordinating comprises causing the respective devices to execute the set of two or more related processes that perform substantially similar operations;
• receive a data set for the set of two or more related processes from the respective devices, wherein receiving the data set comprises receiving one or more operational states of the related processes from each of the respective devices, and wherein the operational states of the related processes each define one or more attributes of the corresponding processes and is associated with one or more respective partitions of a database on the controller device;
• read a previous data set for the set of two or more related processes from the respective devices, wherein reading the previous data set comprises reading one or more previous operational states of the related processes from the respective devices;
• process an update to the one or more previous operational states from the one or more received operational states of the related processes processing, by the controller device, an update to the one or more previous operational states from the one or more received operational states of the related processes, wherein processing the update includes determining that the one or more previous operational states of the related processes and the one or more received operational states are associated with the same one or more respective partitions of the database;
• in response to processing the update, aggregate the one or more received operational states of the related processes with the one or more previous operational states of the related processes to form aggregated data of updated operational states;
• and
• generate a message comprising data representing the aggregated data of updated operational states.

A computer-readable storage medium comprising instructions for causing at least one programmable processor of a computing device to:

• coordinate execution of a set of two or more related processes executed by respective devices in the virtual network, wherein coordinating comprises causing the respective devices to execute the set of two or more related processes that perform substantially similar operations;
• receive a data set for the set of two or more related processes from the respective devices, wherein receiving the data set comprises receiving one or more operational states of the related processes from each of the respective devices, and wherein the operational states of the related processes each define one or more attributes of the corresponding processes and is associated with one or more respective partitions of a database on the computing device;
• read a previous data set for the set of two or more related processes from the respective devices, wherein reading the previous data set comprises reading one or more previous operational states of the related processes from the respective devices;
• process an update to the one or more previous operational states from the one or more received operational states of the related processes;
• in response to processing the update, aggregate the one or more received operational states of the related processes with the one or more previous operational states of the related processes to form aggregated data of updated operational states, wherein processing the update includes determining that the one or more previous operational states of the related processes and the one or more received operational states are associated with the same one or more respective partitions of the database;
• and
• generate a message comprising data representing the aggregated data of updated operational states.
