Remember the days of standing in line at the bank just to update your passbook? The printer would make that zzzt-zzzt sound, and if the ink was low, you couldn’t even read your balance. Today, whether you use SBI YONO , HDFC NetBanking , or ICICI iMobile , you just click "Download Statement," and boom —a 6-month history appears on your screen as a neat PDF. But have you ever wondered how the bank does that? Think about it: A bank like SBI has over 45 crore customers . If every customer generates a 3-page statement every month, that is 135 crore pages of data every single month. If the bank saved these as normal PDF files on a computer, their hard drives would crash in minutes. Plus, finding your specific statement among 135 crore others would take hours.

Case Study: Secure IVR Spring Cloud Microservices Deployment on Azure

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...
