What cloud do I use Spring initializr for?

I’m using aws rds → mysql → Sprin boot → unreal

Uploading the dedicated server to the EC2.

I tried to use Spring initializr by uploading it to an EC2 server with a dedicated server, but the Spring build process is lagging too much and the server sometimes stops.

Even though the dedicated server is not working.

So I think. Isn’t Spring initializr not fit for Aws EC2?

So I’d like to ask for your opinion. What cloud services do you recommend uploading Spring Initializr to?
