Case Study: Secure IVR Spring Cloud Microservices Deployment on Azure 📘 Case Study: Secure IVR Spring Cloud Microservices Deployment on Azure with App Configuration, Key Vault, and DevSecOps 🔹 Executive Summary Financial institutions rely heavily on IVR (Interactive Voice Response) systems to deliver customer self-service options. Traditionally, these backends were monolithic and difficult to scale, secure, and maintain. This case study explores how a bank modernized its IVR backend APIs — Identification, Authentication, and Card Services — by deploying them as Spring Cloud microservices on Azure Kubernetes Service (AKS). The solution leverages Azure App Configuration and Azure Key Vault for centralized config and secrets management, integrated with a DevSecOps pipeline (GitHub, Jenkins, SonarQube, Veracode) for secure, automated delivery. 🔹 Business Challenges Decentralized configuration scattered across multiple services. Secrets exposure risks: credenti...
