PulseHealth Chemist & Diagnostics (a regional healthcare and pharmacy chain) operated 150 offline retail pharmacies. To capture the growing digital healthcare market, PulseHealth sought to launch PulseDirect—an online healthcare application enabling patients to upload prescriptions, order medicines for same-day doorstep delivery, and consult online doctors.
To support their flagship “Big Billion Health Sale”—where order volume was projected to spike by 500% in a single hour—PulseHealth partnered with KAP Cloud Solutions. KAP Cloud Solutions architected an automated, highly secure AWS Elastic Kubernetes Service (EKS) cloud infrastructure that enabled seamless online medicine ordering, strict data security compliance, and zero-downtime massive auto-scaling.
Core Business & Technical Challenges
Before partnering with KAP Cloud Solutions, PulseHealth faced severe digital transformation roadblocks:
- Monolithic Software Constraints: The legacy inventory app was built as a single monolith. Adding online payment gateways or e-prescription features risked bringing down the entire offline store billing system.
- Surge Traffic Vulnerability: Traditional server setups couldn’t handle massive surge sales like the “Big Billion Health Sale.” System crashes during sales led to lost revenue and customer frustration.
- E-Prescription & Security Compliance: Handling sensitive medical data and digitized prescriptions online required end-to-end encryption to meet stringent healthcare privacy regulations and prevent data leaks.
KAP Cloud Solutions Engineering Blueprint
KAP Cloud Solutions designed a modern, cloud-native DevOps and Kubernetes framework on AWS:

- Legacy to Cloud Microservices Migration: KAP Cloud Solutions decoupled the application into independent microservices (Catalog, Order Processing, e-Prescription Verification, Payment Gateway) containerized via Docker.
- AWS EKS Kubernetes Cluster Deployment: Deployed a multi-AZ (Availability Zone) AWS Elastic Kubernetes Service (EKS) cluster managed with Infrastructure as Code (IaC) using Terraform.
- Automated Auto-Scaling for “Big Billion Days”:
- Horizontal Pod Autoscaler (HPA): Dynamically scales individual application containers (Pods) up or down based on real-time CPU and memory usage.
- Cluster Autoscaler & AWS Karpenter: Automatically adds or removes AWS EC2 worker nodes in under 30 seconds when traffic surges during flash sales.
- End-to-End DevSecOps & Data Encryption:
- Prescription images and patient data are encrypted in transit (TLS 1.3) and at rest using AWS KMS (Key Management Service).
- Integrated automated security checks into the CI/CD pipeline to scan every deployment for security vulnerabilities.
