Deploy your FastAPI app to Microsoft Azure
Step-by-step deployment help for FastAPI apps on Microsoft Azure. We fix FastAPI-specific deployment issues, configure Microsoft Azure, and get your app live. From $19.
FastAPI issues we fix before deploying
Common FastAPI problems that affect Microsoft Azure deployments.
Blocking calls inside async endpoints
Synchronous database calls, file operations, or HTTP requests inside async def endpoints block the entire event loop, making your API unresponsive under load.
Missing authentication on endpoints
API routes that handle sensitive data or actions without any auth middleware — Depends() for authentication is simply not included in the route definition.
No CORS configuration
CORSMiddleware either missing (blocking all cross-origin requests) or set to allow_origins=['*'] (allowing any website to call your API).
Pydantic models without validation constraints
Request models that accept any string length, any number range, and any format. No Field() constraints, so invalid data flows through your system.
Microsoft Azure deployment issues we check for
Common Microsoft Azure problems that break FastAPI apps in production.
App Service plan on wrong pricing tier
AI tools provision Free or Basic tier App Service plans that lack autoscaling, custom domains, and SSL — causing issues when traffic grows beyond trivial levels.
CORS not configured on Azure Functions
Azure Functions require explicit CORS configuration in the portal or host.json. AI-generated frontends fail silently when API calls are blocked by missing CORS headers.
Managed Identity not used for service connections
AI-generated code embeds connection strings and secrets directly in environment variables instead of using Azure Managed Identity for secure, keyless authentication.
Deployment slots not configured for zero-downtime
Production deployments happen directly to the main slot, causing downtime during each deploy. Staging slots are available but never configured by AI tools.

Frequently asked questions
How do I deploy a FastAPI app to Microsoft Azure?
We handle FastAPI deployments to Microsoft Azure end to end. Start with our code audit ($19) to identify deployment blockers specific to your FastAPI project, then we configure Microsoft Azure, fix issues, and get your app live in production.
What FastAPI issues affect Microsoft Azure deployments?
FastAPI projects commonly have blocking calls inside async endpoints and missing authentication on endpoints. On Microsoft Azure, these combine with app service plan on wrong pricing tier and cors not configured on azure functions to cause deployment failures.
Can SpringCode deploy my FastAPI project to Microsoft Azure?
Yes. We specialize in deploying FastAPI applications to Microsoft Azure. We audit your codebase for FastAPI-specific issues, configure Microsoft Azure correctly, and handle the full deployment so your app runs reliably in production.
What does FastAPI deployment to Microsoft Azure cost?
Our code audit ($19) identifies all Microsoft Azure deployment blockers in your FastAPI project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
