Case Study - Secure Healthcare Platform Modernization

AKNA Health Insurance TPA faced critical operational challenges that impacted performance, security, and service delivery for its members, insurers, and network hospitals. The existing infrastructure lacked a global content delivery and edge security layer, making it difficult to handle traffic spikes, ensure secure access, and deliver timely services to a geographically dispersed user base.

Key Challenges

• High Latency & Service Delays: Manual routing of requests to origin servers caused slower response times for members and partner hospitals across different regions.
• Unpatched Security Gaps: Lack of automated certificate management, incomplete WAF configurations, and limited access controls exposed workloads to potential vulnerabilities.
• Security Risks: Publicly accessible application endpoints and backend servers increased the risk of unauthorized access, data breaches, and non-compliance with regulatory standards.
• Scalability Constraints: The system struggled to handle sudden surges in traffic, such as claim processing peaks or enrollment periods, resulting in slower services.
• Operational Inefficiencies in Notifications: Reliance on traditional or third-party messaging systems for claim status, alerts, and communications was less reliable and more costly.

i2k2 Networks designed and delivered a secure, production-grade AWS-native solution for AKNA Health Insurance TPA, following the AWS Well-Architected Framework. The solution emphasized global content delivery, scalability, and security while ensuring compliance with healthcare regulations and minimizing operational risk.

Content Delivery & Performance Optimization

• Implemented Amazon CloudFront as a global Content Delivery Network (CDN) to accelerate access to static and dynamic content, including member portals, claim dashboards, and policy documents.
• Integrated CloudFront with Application Load Balancer (ALB) and Amazon S3 origins to optimize traffic routing and reduce backend load.
• Configured intelligent caching policies, HTTP/2, and Gzip/Brotli compression to improve page load times and minimize bandwidth usage for end-users across India.
• Enabled Origin Shield to further protect origin servers while ensuring low-latency delivery for critical healthcare services.

Security & Compliance

• Integrated AWS WAF with CloudFront to protect web applications against SQL injection, XSS, bot traffic, and other web exploits.
• Enforced HTTPS with ACM-managed SSL certificates to ensure secure communication for member data and regulatory compliance.
• Restricted access to backend services by allowing traffic only from CloudFront and ALB, minimizing the public attack surface.
• Deployed workloads in private subnets with NAT Gateways and VPC endpoints for secure outbound communication.

Scalability & High Availability

• Utilized CloudFront’s global edge locations to handle traffic spikes during claim submissions, policy updates, and peak user activity, without impacting origin servers.
• Deployed EC2 instances in Auto Scaling Groups to dynamically adjust capacity for application servers, MongoDB, and MySQL workloads.
• Ensured high availability across multiple Availability Zones in the Mumbai region, supporting continuous operations for member services.

Notifications & Operational Efficiency

• Recommended Amazon Simple Email Service (SES) for secure notifications, including claim updates, policy alerts, and member communications.
• Improved reliability and delivery efficiency with SES, achieving >98% successful email delivery compared to <75% previously.
• Enabled CloudWatch and CloudTrail for monitoring, logging, and auditing to meet compliance requirements for healthcare operations.

Security and Monitoring:

Configured AWS WAF integrated with Amazon CloudFront to protect aknatpa.com against SQL injection, XSS, bot attacks, and other common web exploits, safeguarding sensitive health insurance data.

• Implemented AWS Certificate Manager (ACM)–managed SSL/TLS certificates to ensure uninterrupted, secure HTTPS communication for member portals, hospital access, and insurer interactions.
• Migrated workloads to private VPC subnets with NAT Gateways and VPC Endpoints, ensuring secure outbound access and isolation of critical servers such as claim processing, member management, and payment systems.
• Deployed Amazon CloudWatch and AWS CloudTrail to monitor performance, log system activity, and provide full audit trails for regulatory compliance (IRDAI and internal policies).

• Improved application performance: Global content delivery via Amazon CloudFront ensured faster page loads and low-latency access for members, hospitals, and insurance partners across India.
• Zero downtime for critical services: Automated deployment strategies and CloudFront edge caching allowed uninterrupted access to the portal and member services during updates.
• Enhanced reliability for notifications and communications: Integrated Amazon SES improved the delivery of claim updates, policy notifications, and alerts, achieving over 98% success rate.
• Strengthened security posture: Web Application Firewall (WAF), ACM-managed SSL certificates, and private subnet isolation significantly reduced exposure to attacks, protecting sensitive member and policy data.
• Seamless scalability during peak traffic: CloudFront, ALB, and Auto Scaling ensured smooth operations even during high-demand periods, such as claim surges or mass policy enrollment.
• Operational efficiency and cost optimization: Offloading static and dynamic requests to CloudFront reduced backend server load and origin bandwidth costs.

By leveraging AWS-native services, i2k2 Networks successfully delivered a production-grade, secure, and highly scalable content delivery and application infrastructure solution for AKNA Health Insurance TPA. The solution addressed performance bottlenecks, security challenges, and scalability requirements while optimizing operational costs and ensuring regulatory compliance. AKNA can now confidently deliver reliable, secure, and high-performance services to policyholders, insurers, and network hospitals across India, while maintaining operational efficiency and business continuity.
