You can download and install Apache Hello World for Java Enterprise Edition on an enterprise scale (assuming of course that you have sufficient bandwidth remaining for this month).
Support is available for "Apache Hello World Enterprise Edition" from Tata Consulting Services, HP Consulting Service and if that's not expensive enough for you, Price Waterhouse are now offering dedicated fly-in-from-overseas teams who have the skills and experience to roll out "Enterprise Hello World" in record implementation time of generally less than 6 months, not including customisations to your environment, which will be built by university graduates at $1,200 per day.
Business Analysts are ready to write sophisticated UML diagrams to map out how to integrate Apache Hello World in carefully considered ways that match your business processes.
New Relic will provide application instrumentation for your Apache Hello World implementation to ensure if (when?) it goes down you'll be able to rapidly pinpoint the general 50,000 code lines area that the fault might lie.
