Abstract

Disclosed herein are systems, devices, and methods for providing auto-scaling in a cluster of device instances. In one embodiment, a method is disclosed comprising updating, using a distributed counter, a metric associated with one or more instances executing a network application; identifying that the metric has exceeded a threshold defined in a scaling policy based on comparing the distributed counter to the scaling policy; identifying a command to execute in response to the metric exceeding the threshold; and executing the command to modify the one or more instances.

Claims20

Dependent claims

A device comprising:

a processor;
a memory storing a scaling policy and a master enabled flag, the scaling policy and master enabled flag initialized in the memory during an instantiation of a virtual machine image, the master enabled flag indicating a master status when in a set state;
and
a storage medium for tangibly storing thereon program logic for execution by the processor, the stored program logic comprising:
logic, executed by the processor, for executing the virtual machine image,
logic, executed by the processor, for transmitting a first count value to one or more instances, the one or more instances executing respective distributed counters,
logic, executed by the processor, for receiving a second count value from the one or more instances,
logic, executed by the processor, for updating, using a distributed counter, a metric associated with the one or more instances based on the second count value,
logic, executed by the processor, for identifying that the metric has exceeded a threshold defined within the scaling policy,
logic, executed by the processor, for identifying a command to execute in response to the metric exceeding the threshold,
logic, executed by the processor, for executing the command to modify the one or more instances, and
logic, executed by the processor, for updating the master enabled flag, the updating disabling execution of the scaling.
