Two servers each for HTML and Java Jersey Rest APIs or Single Tomcat Webapp

This is a question to design my dynamic website. It should have a java REST APIs beckend and static HTML view.

• Should I keep my HTML content in separate server(like AWS S3) and REST APIs in Tomcat(hosted in a EC3 instance)

OR

• Should I keep index.jsp as my starting point of application. Thus making both HTML and JAVA sit together in the same project. And If I do take this option, will I be able to use Angular and Bootstrap with this or not.

Hope you understood the question :)
