Pooling user interface (UI) engines for cloud UI rendering

A system comprising:

• one or more processors;
• a non-transitory memory;
• and
• one or more programs stored in the non-transitory memory, which, when executed, cause the one or more processors to perform operations comprising:
• receiving multiple requests for user interfaces (UIs) from multiple client devices, wherein the multiple requests include states of the UIs on the multiple client devices;
• dividing the multiple requests into a plurality of groups based at least in part on the states of the UIs, wherein a respective group of the plurality of groups corresponds to requests for a set of UIs from a respective set of client devices;
• and
• assigning a pool of UI engines in a virtual machine (VM) to render the set of UIs for the respective set of client devices based on one or more of characteristics of the set of UIs and characteristics of the respective group.

A non-transitory computer-readable media including instructions, which, when executed by a device including one or more processors, cause the device to:

• receive multiple requests for user interfaces (UIs) from multiple client devices, wherein the multiple requests include states of the UIs on the multiple client devices;
• divide the multiple requests into a plurality of groups based at least in part on the states of the UIs, wherein a respective group of the plurality of groups corresponds to requests for a set of UIs from a respective set of client devices;
• and
• assign a pool of UI engines in a virtual machine (VM) to render the set of UIs for the respective set of client devices based on one or more of characteristics of the set of UIs and characteristics of the respective group.
