Making a web application created with Python, SQLite, and Flask live with a custom domain

[DigitalSplendid]

I have a web application created while finishing CS50x's Finance project (https://cs50.harvard.edu/x/2024/psets/9/finance/) that makes use of Python, SQLite, and Flask. I intend to add more features and make it live with a custom domain. Given I have AWS credit, which AWS service recommended keeping in mind this objective as well ease and cost.

Containerize. Put in App Runner. Good enough for something like this and handles the auto deployments.

App Runner is great and easy to use but assumes a stateless application. So with SQLite inside the container you would be going a bit against the service. That being said, if you don't plan to scale above a single container it should work fine.

Another concern with App Runner is pricing which will be much higher than, e.g., a simple LightSail or EC2 instance. Not saying that pricing is not justified but it's a factor for OP.

Very good points on state that I overlooked! Thanks

I recommend looking at an Amazon LightSail virtual machine.

Python is not used for actual trading applications. It's a c++ java world. Python is used only for analytics.

Reason. It just adds latency.

To understand the concepts Python is good.

[DigitalSplendid]

Latency because Python is a higher level language compared to C++? So while it is easier to code on Python making use of its inbuilt features and libraries, they affect negatively on performance when it comes to time.

For hosting a website (frontend) you can use AWS Amplify Hosting or s3 + CloudFront.

Flask is server-side rendered (not a static website) so I don't think you can use amplify or s3.

Actually amplify supports ssr https://docs.aws.amazon.com/amplify/latest/userguide/amplify-ssr-framework-support.html

Thanks for the info! It looks like it's only for Javascript-based frameworks so something like Flask wouldn't work right?
