Multi-Cloud Workload Identity Federation

Designing secure workload identity federation across AWS, GCP, and Azure using Kubernetes ServiceAccounts, OIDC, and cloud-native identity providers.

Overview

This project focused on replacing long-lived cloud credentials with workload identity federation for Kubernetes workloads deployed across multiple cloud providers.

The Problem

Traditional Kubernetes workloads often rely on static cloud credentials stored as Secrets. While functional, this approach increases operational overhead, complicates credential rotation, and expands the security blast radius if credentials are exposed.
