# Pre-emptive Source Environment Discovery (As-Is Architecture)

## Existing Workload Audit
- **Workload Summary**: Test session retrieval route (Legacy / Pre-existing Environment)
- **Current Hosting**: On-Premises Data Center / Legacy VM Infrastructure
- **Ingress Layer**: Self-managed NGINX Reverse Proxy listening on HTTP/HTTPS
- **Application Runtime**: Monolithic Application Instance (Single Point of Failure)
- **Database Layer**: Self-hosted PostgreSQL Instance (Unreplicated, Local Disk)
- **Queue / Messaging**: Local RabbitMQ Queue Instance

## Current Operational Pain Points & Bottlenecks
- Single-instance compute leading to downtime during maintenance windows.
- Manual scaling capabilities unable to handle unexpected traffic spikes.
- Unencrypted local storage and unmanaged backups creating data loss risks.
- Elevated operational overhead and hardware lifecycle costs.

## Source Component Topology
- `Client` -> `NGINX Proxy` -> `Monolith Application` -> `Local PostgreSQL / RabbitMQ`
