Sorry, this is probably way too meaningful for MD, feel free to move it to a good place, I could not see a good match.

I've got a large Java web application, written the usual way, with servlets, beans, an ORM talking to a MySql database on the back side, and lots of HTML, jsp, CSS, javascript, etc. on the browser side. It all works just fine, plus or minus a few bugs.

For the past few weeks, administering, setting up, configuring servers and networking has been a full time job. I can do it, but I am no better than "average" at it. I'm very good at development, but just barely good enough at network address masks, routing tables, etc. to be dangerous. So I want to outsource operations.

The obvious choice is to find a hosting service for tomcat or glassfish and be happy. That seems to obvious, and not buzzword compliant. To be buzzword compliant, you have to be in the cloud.

I've spend a few hours with each of the websites for App Engine and Amazon EC2. I don't get it. I don't understand what they are actually selling, and I have no idea what it costs. Little things, for example, they charge per "minute" but I don't understand what a minute is for a Tomcat instance. I think of them running always, 24x7 every day of the year. What is a minute in the context?

Anybody know how to translate this new cool stuff to my old brain?

With GAE you got quotas, not minutes
You will also need to migrate from MySQL to the GAE Datastore
