Scalable Backend for 3D Model Processing on Azure

The Problem: The 3D Processing Bottleneck

For companies managing massive catalogs of 3D models (e-commerce, manufacturing, digital twins), traditional geometric processing on monolithic servers quickly becomes a bottleneck.

Decoding, simplifying (decimation), and validating .gltf or .obj files is CPU- and memory-intensive. If the architecture is not designed for horizontal scaling, the system will collapse under demand spikes, causing unacceptable wait times and blocking critical business workflows.

My Solution: Elastic Infrastructure on Azure

I design highly concurrent and resilient backend architectures in .NET 8 and Azure that decouple file ingestion from heavy mathematical processing.

Instead of blocking REST APIs, we orchestrate background workers and distributed message queues, ensuring that the system can absorb massive load spikes (tens of thousands of simultaneous 3D models) by scaling nodes on demand and shutting them down to reduce costs (FinOps).

Technical Approach

Asynchronous Processing: Using Event Driven Architecture (Azure Service Bus) to queue heavy geometry tasks without affecting API latency.
Horizontal Scaling: Implementation of Workers (Azure Container Apps / Azure Batch) that scale from 0 to 100 replicas based on the length of the 3D processing queue.
Efficient Storage: Optimized streams and direct multipart uploads to Azure Blob Storage using SAS tokens (Zero-Trust) to bypass RAM limits.

Use Cases

Automatic Mesh Validation: Automatic review of geometry, watertightness, and intersections on B2B SaaS platforms, rejecting corrupt models without human intervention.
3D Conversion Pipelines: Bulk transformation of heavy formats (STEP/IGES) to web-optimized formats (GLB/glTF) for fast rendering in WebGL or Three.js viewers.
