Performance latency observed with invocations of VIP auth hub APIs from application in the same EKS cluster

Products

• VIP Authentication Hub

Issue/Introduction

Intermittent 45 seconds latency was reported when SSP API calls are invoked.

This happened after APIGW was added onto the same cluster, where Ingress and SSP were already running.

The API calls are invoked from APIGW application hosted in the same EKS cluster.

The data flow is :

APIGW -> Ingress -> SSP

The delay seems happening between APIGW and ingress per logs.

There was 45 seconds gap between requests. No activity is logged or happening in between those 45 seconds.

Environment

AWS, EKS kubernetes: 1.30

VIP auth hub: 3.3.4.2033 

Resolution

Authentication Hub did not cause the delay.

The latency issue got resolved after updating a NLB (Network Load Balancer) configuration in customer's environment.
