We are using a different style of Automation framework in our project (as per client request) wherein we have designed a JSP page and this page contains links and buttons through which each functionality of our application can be accessed (say on the JSP I select 'Purchase' it will open browser whichever is intended and runs a test to verify that functionality). We are using Tomcat server for deployment.

Now my question is if I introduce Selenium Grid setup into the mix (again as requested by client), is it sufficient that I run my Tomcat server on the Hub and I can access my JSP on all the nodes connected?
