Just read the first blog posts (Google App Engine Blog, GR8 Conference, The Aquarium) about the announcement that Java is the next programming language supported on Google App Engine.
This is so funny, as I think just before Google released the announcement I put a question on the Google App Engine discussion group about when we can expect the new language and which language it would be. So my qusetion is answered now.
Since Google App Engine was announced I've always followed it with interest. I'm really excited/interested in the Cloud computing model so I don't have to maintain a deployment server/server park myself. Also the fact that I will just use more resources on the cloud infrastructure when my application needs is just great. I don't have create a cluster or whatever myself.
The reason I put the question on the forum yesterday was that I'm working on a small personal application I like to host on the internet somewhere in the future. Important thing is that the hosting has to be cheap when starting up. I've looked into Mor.ph but it would still cost me $31 a month to host my Java application. This does not sound expensive, buy hey I'm not a business!
In the past I hosted a couple of PHP websites using Drupal and I must say good PHP hosting is cheap and works very good. So I was already thinking of alternative scenario to develop my application in PHP, and not in Grails ;-(
I had already downloaded CakePHP and was experimenting a bit with it. I must say CakePHP is really easy to learn for Grails developers as it uses a lot of the same concepts as Grails and also RoR.
But with the annoucement of Google that Java will be supported I will be putting my PHP alternative in the fridge again. Also a very big plus that SpringSource's Groovy team has worked together with Google to make sure Groovy works well on Google App Engine. Let't hope the same thing counts for Grails one day.
