PhotoRobot Architecture & Data Flow

PhotoRobot Cloud is a cloud-native architecture utilizing Google Cloud Platform services for scalable processing, secure storage, and reliable delivery.

‍

High-Level Architecture

Compute

• GCP-managed compute resources (autoscaled)
• Secure containerized workloads
• Shielded VMs and workload identity

‍

Storage

• Google Cloud Storage buckets (EU region)
• Versioning and access controls
• Encryption at rest with GCP-managed keys

‍

Networking

• HTTPS/TLS 1.2+ for all inbound/outbound traffic
• No public access to internal services
• Identity-aware access at perimeter

‍

External Integrations

• OCR: Google Vision API
• APIs: REST API for customer systems
• Webhooks: Optional for event notifications

‍

Data Flow (Conceptual)

1. Upload
   
   • User uploads images or files through the authenticated interface (HTTPS).
     ‍
2. Processing
   
   • OCR called if enabled 
   • Transformations and metadata generation 
   • Actions logged for auditability 
     ‍
3. Storage
   
   • Objects stored in Google Cloud Storage 
   • Metadata stored in cloud-managed database 
     ‍
4. Delivery
   
   • Processed results accessible via UI or API 
   • Optional exports via standard export functions 

‍

Design Principles

• No raw data leaves the EU region
• All processing isolated inside GCP
• No direct access to underlying infrastructure by third parties
• Minimal external dependencies (only trusted Google Cloud services)
