Resilient Auto-Scaling of Microservice Architectures with Efficient Resource Management

Horizontal Pod Auto-scalers (HPAs) are crucial for managing resource allocation in microservice architectures to handle fluctuating workloads. However, traditional HPAs fail to address resource disruptions caused by faults, cyberattacks, maintenance, and other operational challenges. These disruptions result in resource wastage, service unavailability, and HPA performance degradation. To address these challenges, we propose SecureSmart HPA, a resilient and resource-efficient HPA for microservice architectures. SecureSmart HPA monitors microservice resource demands, detects disruptions, evaluates resource wastage, and dynamically adjusts scaling decisions to enhance the resilience of auto-scaling operations. Furthermore, SecureSmart HPA enables resource sharing among microservices, optimizing scaling efficiency in resource-constrained environments. Experimental evaluation demonstrates that under disruption severities of 25%, 50%, and 75% resource wastage, SecureSmart HPA delivers robust performance, underscoring its resilience and efficiency in volatile, resource-constrained environments.
