Designing Cost-Optimized EKS Architectures for Telecom-Grade Availability and Scalability: A Comprehensive Review

The cloud-native platform evolution had a major effect on the telecommunications business, where they are distributed in a way that allows the service providers to provide high and predictable availability, high performance, and efficient operations. Amazon Elastic Kubernetes Service (EKS) is a managed K8s service architecture delivering robust infrastructure up to telecom-level workloads. Nevertheless, cost-efficiency is also an essential aspect, next to availability and scalability. This review examines the architectural best practices, deployment best practices, and platform optimizations that lead toward designing cost-optimized EKS architectures with the objective of a telecom use case. The article brings out aspects of node provisioning, availability zone, storage management, network configuration, monitoring, and automation, which offer an overview guide towards attaining carrier-grade service levels with reduced infrastructure spending. The priority is given to the trade-off between being highly available and cost-effective via design patterns that are reinforced by empirical findings of scholarly publications.
