Global heap size coordination of garbage collected workloads

One or more non-transitory computer-readable media storing instructions which, when executed by one or more processors, cause the one or more processors to:

• execute, in a managed cloud computing environment, a plurality of applications that each have a corresponding local garbage collector in a plurality of local garbage collectors;
• execute a global garbage collection manager, of the managed cloud computing environment, which communicates with the local garbage collectors via one or more cloud runtimes, wherein the global garbage collection manager maintains global statistics information comprising statistics information communicated to the global garbage collection manager from each of the local garbage collectors;
• generate, by a first local garbage collector associated with a first application, first statistics information of the first application in response to a first local garbage collection operation executed by the first local garbage collector;
• communicate, from the first local garbage collector, the first statistics information to the global garbage collection manager;
• and
• dynamically modify, by the global garbage collection manager, a heap size associated with the first application, based on the first statistics information and the global statistics information.

An apparatus, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to execute the process comprising:
• executing, in a managed cloud computing environment, a plurality of applications that each have a corresponding local garbage collector in a plurality of local garbage collectors;
• executing a global garbage collection manager, of the managed cloud computing environment, which communicates with the local garbage collectors via one or more cloud runtimes, wherein the global garbage collection manager maintains global statistics information comprising statistics information communicated to the global garbage collection manager from each of the local garbage collectors;
• generating, by a first local garbage collector associated with a first application, first statistics information of the first application in response to a first local garbage collection operation executed by the first local garbage collector;
• communicating, from the first local garbage collector, the first statistics information to the global garbage collection manager;
• and
• dynamically modifying, by the global garbage collection manager, a heap size associated with the first application, based on the first statistics information and the global statistics information.
