📌 Atrium Health at Vectoflow – Scalable & Cost-Effective Cloud Workloads

VF AH Architecture

Overview

Built a cost-efficient cloud architecture for Healthcare client: Atrium Health, ensuring scalable and optimized workloads. Leveraged automation, serverless solutions, and data lifecycle management to reduce infrastructure costs while maintaining performance.

🔍 Architecture Component Breakdown

🚪 Badge Access Control (API + DB)

Manages secure access to hospital zones based on staff roles and visitor privileges. Ensures badge issuance is tightly mapped to physical access policies, minimizing unauthorized entry.

📤 AWS Lambda (Badge Issuance Flow)

Automates badge creation workflows in real-time, reducing manual approval bottlenecks. Enables fast response to identity changes, such as emergency clearances or revokes.

🧠 Third-Party ID Verification (IDM)

Integrates with hospital identity providers for secure access provisioning. Ensures only verified individuals are onboarded into access workflows with full audit trails.

📦 Amazon S3 + Glacier

Stores logs of badge print events, access history, and configuration changes. Lifecycle policies archive long-term logs to Glacier, supporting compliance retention rules.

📈 CloudWatch + CloudTrail

Tracks badge events, anomalies, and system health. Enables proactive alerting and compliance auditing across badge creation, approval, and entry logs.

🔐 AWS KMS

Encrypts sensitive access data including badge templates and user identity information. Supports granular key policies for hospital-level compliance enforcement.

⚠️ Alert Workflow (Lambda + SNS)

Sends real-time alerts for failed badge print attempts or policy violations. Ensures rapid response by IT/security teams to potential physical access issues.

🔄 Self-Healing (Auto Revert Config)

Detects drift from badge policy configuration and auto-corrects it using predefined templates. Minimizes downtime or security exposure due to misconfiguration.

🧩 API Gateway

Facilitates secure API access for integration with mobile badge apps and facility systems. Enforces throttling and access controls to prevent misuse or overload.

🏥 Custom Hospital Logic (Per Client)

Supports client-specific rules such as visiting hours, operating room restrictions, and staff shift overrides. Adaptable logic enables white-label deployment across hospitals.
