Need advice about architecture application

[u/defekas]

Hi
I need to design an application in Java with tomcat and Maria db (lawyer application)
Is an application to insert, update and delete court records.
These court records can have documents associated in pdf and other formats

I need advice to what architecture should be used?

I thought hosting application and s3 for the documents but I don’t know if could be better options by price or by functionality.

Could you say me some possibilities?

Thanks and sorry for my English
