Hello Karel, Here's some initial responses to your question on using App Engine as a gaming back end..
> About 1500 active users cause on average 3 million page views each day (90 > million each month), for a bandwidth usage of 2,5GB per month. This should not be a problem.. >About 250 SQL queries are executed each second, and the database is slightly >less than 1 GB large, with hundreds of tables. Can this be handled by a nonSQL >db? Or is a relational DB a definite requirement? The GAE Datastore can definitely scale to 250 qps. There's no effective limit to datastore qps, given that access patterns are sufficiently distributed. We currently have customers doing tens of thousands of qps. >Is GWT and app engine with the data store a viable platform for a game with >these specifications? It should be, although having GWT in the mix is not a requirement. You could also code your app directly in HTML5, or you could also look into using the new multi-platform game development platform: "PlayN" (http://code.google.com/p/playn/) What might be helpful is to create a small prototype app on App Engine, and see if this environment will work for you. Once you're more familiar with App Engine, you'd be in a much better position to make the call. You can always post further questions to this group, (or the PlayN group..) Hope this helps! -Chris On Sep 12, 7:00 am, Karel Crombecq <[email protected]> wrote: > Hey guys, > > I am currently investigating possibilities for writing a sequel to the > popular text-based browser game that I released in 2001 called Castle Quest > 2 (http://www.castlequest.be).
