Auto scaling method and device considering application service response time

An auto scaling device considering an application response time, comprising:

• a processor;
• and
• a memory connected to the processor,
• wherein the memory stores program instructions executed by the processor to
• restrict resources of pods distributed according to setting of an initial resource quota in a name space,
• collect a monitoring metric of an application for which service is requested, and
• delay scaling by using at least one of the collected monitoring metric, a recent data reflection rate of a service predetermined in a custom resource, a service level agreement (SLA) of a service, and an SLA threshold when the resources of pods are insufficient.

An auto scaling system considering an application response time, comprising:

• a cluster manager restricting resources of pods distributed according to setting of an initial resource quota in a name space;
• an application monitoring unit collecting a monitoring metric of an application for which service is requested;
• and
• a custom scaling controller determining whether to change a resource quota by using the collected monitoring metric, a recent data reflection rate of a service predetermined in a custom resource, a service level agreement (SLA) of a service, and an SLA threshold when the resources of pods are insufficient, and updating the initial resource quota in the name space to a first resource quota when the change of the resource quota is required.

An auto scaling method considering an application response time in a device including a processor and a memory, the method comprising:

• restricting resources of pods distributed according to setting of an initial resource quota in a name space;
