Application Load Balancer with health checks and auto-scaling support.
AWS WAF enabled for OWASP Top 10 and common web threat protection.
Application Server Layer
Backend APIs and core services hosted on secure EC2 instances.
Authentication (Cognito), Programs (RSS Sync), Appointments, Resources, Reporting.
Auto Scaling Groups ensure high availability and fault tolerance.
Data & Storage Layer
Encrypted PostgreSQL database with automated backups and multi-AZ deployment.
Amazon S3 for file storage, resource uploads, and exports.
Encryption at rest and in transit enabled across services.
Background Processing
Serverless processing for asynchronous tasks and scheduled operations.
Handles RSS feed sync and background task processing.
SQS for async job queueing. EventBridge for daily scheduled RSS sync (2 AM).
Monitoring & Observability

Resilience
Offline-first with intelligent recovery
Seamless functionality in low-connectivity environments with automatic sync and conflict resolution.
Offline Storage
SQLite/Realm for mobile, IndexedDB for web. Catalog and resources cached locally.
Sync Workers
Service workers queue actions. Sync starts when connection detected with exponential backoff.
Conflict Resolution
Last-Write-Wins (LWW) logic. Deduplication based on User ID + Timestamp.
Failure Recovery
Auto-healing pods. DB failover promotes read replica within 30-60s.
Region Failover
Traffic Manager routes to secondary region (US-West) during complete outage.
API Design
RESTful APIs with comprehensive documentation
Clean, versioned architecture with OpenAPI specification and integration-friendly endpoints.
Deployment
Zero-Downtime Deployments
A structured release process designed for reliability, stability, and uninterrupted service.
Automated Code Validation
Every update goes through structured code review and automated build validation to ensure stability before release.
Secure Application Build
Mobile and web applications are compiled and prepared for deployment with environment-specific configurations.
Pre-Production Validation
New releases are first deployed to a controlled staging environment for QA review, functional testing, and integration validation.
Controlled Live Deployment
Approved releases are deployed to AWS infrastructure in a controlled manner to avoid disruption to live users.
Post-Deployment Monitoring
System logs and performance metrics are actively monitored through AWS CloudWatch to detect anomalies early.
