Given the national scale of eStock and the sensitivity of healthcare data, security, reliability, and scalability were critical requirements from the outset. It was important to ensure the system could further adapt to evolving healthcare processes and integrate seamlessly with multiple national digital systems.
Hence, we architected the system to handle thousands of concurrent users without performance degradation, while ensuring scalability, uninterrupted access to accurate data for decision‑making, and compliance with strict industry standards through:
- AWS‑based infrastructure compliant with HIPAA and ISO standards to protect sensitive medical information
- Daily full and hourly incremental backups to ensure 24/7 uptime and operational continuity
- Horizontal & vertical scaling for 10,000 concurrent users, ensuring stable performance even during peak demand
- AWS triple replication between availability zones to protect against data loss and ensures high availability
- IAM, WAF, security groups to secure robust access control and defense against unauthorized access
