Still with me?
Anyway he claimed/joked? about the 30 servers needed for the application described on JSFCentral.
That got me thinking, we migrated a pretty complex application from Domino To JEE last year and of course the management thought that things would get a lot simpler/cheaper in the new environment.

Well, if counting servers is an indication...

Only listing servers for the SAAS website (so excluding internal software, webservices and other stuff) we started with the following Linux servers:
2 Apache
1 SQL Logging server
1 Tomcat search server
1 SQL Search server (plus 1 backup)
2 clustered Domino Webservers
1 Domino webserver for 3rd party connections
1 Domino Hub
1 Domino Index
1 Domino ‘Edit’ server (backoffice/maintenance/agents)
1 Windows server for PDF processing (OCR server)
TOTAL: 12

And we now have:
2 Apache
1 SQL Logging server
2 Tomcat Webservers
1 Tomcat Batch server (agents)
3 Elasticsearch search servers
2 clustered SQL servers
1 Windows server for PDF processing (OCR server)
TOTAL: 12

Now as you can see this environment was already partly JEE-iffied, so there were already some additional servers, which taints the comparison. So, if anything the number of servers overall probably increased rather than decreased. Plus a change in the hardware specs of course; used to be 32bit with 8Gb memory and now 64bit with 32Gb. But who's counting... ;)
