[google-appengine] Why so many instances?
Thanks for the new Instances dashboard - it's neat to know. I'm curious though, why are so many instances running? I have one (java) app that gets a steady 0.5 hits/s, and another (python) app that gets a steady 2.5 hits/s. The 0.5 hits/s Java app is running 4 instances. The 2.5 hits/s Python app is running 6 instances. Obviously I don't mind that Google devotes so many resources to serving my application, but it does seem odd. Does GAE need this many instances to serve so few requests? If my Java app surges to 50 hits/s, will I consume 400 instances??

The max instances per app are about 30. -- keakon On Sat, Oct 16, 2010 at 9:30 AM, Jeff Schnitzer wrote: > Thanks for the new Instances dashboard - it's neat to know.

Re: [google-appengine] Why so many instances?
I don't think it scales linearly like that. We're working on improvements to the request scheduler so that we can make better use of existing resources, so be on the lookout for that. This is just us providing more transparency into how many instances are serving your application so it's easier to try to figure out your auto-scaling situation. -- Ikai Lan Developer Programs Engineer, Google App Engine Blogger: http://googleappengine.blogspot.com Reddit: http://www.reddit.com/r/appengine Twitter: http://twitter.com/app_engine On Fri, Oct 15, 2010 at 6:30 PM, Jeff Schnitzer wrote: > Thanks for the new Instances dashboard - it's neat to know.
