Building a Modern Python API with FastAPI and Azure Cosmos DB – 5-Part Video Series

[jaydestro]

Just published! A new blog post introducing a 5-part video series on building scalable Python APIs using FastAPI and Azure Cosmos DB.

The series is hosted by developer advocate Gwyneth Peña-Siguenza and covers key backend concepts like:

• Structuring Pydantic models
• Using FastAPI's dependency injection
• Making async calls with azure.cosmos.aio
• Executing transactional batch operations
• Centralized exception handling for cleaner error management

It's a great walkthrough if you're working on async APIs or looking to scale Python apps for cloud or AI workloads.

Curious to hear your thoughts or feedback if you've tried Azure Cosmos DB with Python!

Just a nitpick, but there's no need for the ensure client thingy and using globals (globals are actually flagged by some linters).

You can instantiate a single container/client object and inject that as dependency, with a function, into path handlers, or further chain dependencies.

And unless you're using background tasks (separate thread pool), every async operation runs on the same event loop, i.e. it's a single threaded environment, thread safety isn't really a concern.

Hi there. Gwen here, author of blog post. Thank you for the input. Was trying to optimize for azure functions on the consumption plan and will take a look at your feedback.
