Deploy FastApi to AWS Lambda for Serverless Hosting
If you’re looking to deploy a FastApi application to AWS Lambda for serverless hosting, you’re in the right place. AWS Lambda is a serverless computing service that allows you to run code without provisioning or managing servers. FastApi is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints.
Steps to Deploy FastApi to AWS Lambda
- Install Serverless Framework: If you haven’t already, install the Serverless Framework by running
npm install -g serverlessin your terminal. - Create a FastApi project: Create a new FastApi project or use an existing one.
- Configure Serverless Framework: Create a serverless.yml file in your FastApi project directory and configure it with the necessary AWS Lambda settings.
- Deploy to AWS Lambda: Run
serverless deployin your terminal to deploy your FastApi application to AWS Lambda. - Test your deployed FastApi application: Once deployed, test your FastApi application by making requests to the AWS Lambda URL provided by the Serverless Framework.
Benefits of using AWS Lambda for FastApi Hosting
- Scalability: AWS Lambda automatically scales your FastApi application based on incoming traffic, so you don’t have to worry about capacity planning.
- Cost-effective: With AWS Lambda, you only pay for the compute time you consume, making it a cost-effective option for hosting FastApi applications.
- Zero administration: AWS Lambda takes care of server maintenance, capacity provisioning, and automatic scaling, allowing you to focus on building your FastApi application.
Conclusion
Deploying FastApi to AWS Lambda for serverless hosting is a great way to take advantage of the scalability, cost-effectiveness, and zero administration benefits of serverless computing. By following the steps outlined above, you can quickly and easily deploy your FastApi application to AWS Lambda and start serving your API to the world!
i tryed but i got [ERROR] Runtime.ImportModuleError: Unable to import module 'main': No module named 'pydantic_core._pydantic_core' Traceback (most recent call last):
what are the benefits of using AWS Lambda instead of using docker directly on the EC2 machine?
aws lambda deployement of fastapi gives the following error :
[ERROR] Runtime.ImportModuleError: Unable to import module 'users_crud': No module named 'pydantic_core._pydantic_core'
Traceback (most recent call last):
Though the pydantic lib is already installed. Any ideas any clues why ? I am using 3.10 which is now supported by AWS
does it working if i use postgresql as my db?
When you send a request through the lambda, does the app gets initialized again or it stays initialized? so for example if i had object that has longer loading time will it affect the performance?
thanks
Great video. But zip command dosnt work in windows. Please highlight that and if there is any work around please post it too.
In fact, the idea of using fastapi in a lambda is a strange idea in and of itself! The lambda is made for others like stateless event processing. Definitely not for runnig api servers inside.
Vincent you are the freaking man! I tried to do this using 3 other tutorials and I was at it for hours and kept getting stuck at various places. I used your method and was up and going in less than 15 minutes! You need to set up a tip jar or something on YouTube!
Keep going on mate ! Very excited to see your expansion and the knowledge that you will bring along with it !!
i studied biology in college and have no comprehension of the language you are talking in this video.
where'd you pick up all of this technical jargon? i'm assuming it's still much more enjoyable than medical school jargon?
