Or put it another way, the actual "instance" is a very small part of the overall infrastructure.
Static files are not served off your instance (on a VPS they would use CPU cycles, or need a separate VPS/CDN etc) Other capabilities, like image manipulation apis, and memcache etc, are using CPU/memory outside your instance. On a VPS, would need to dedicate some of your instances (or another VPS) memory to hold memcache items. To to provide all the capabilities, that your one little instance can do on GAE, may* well need a substantially larger VPS. Maybe one that costs $0.35 an hour. Or more realistically a larger number of VPSs. * say may, as we dont yet know what the full capabilities of the new instances will be. Which in fact shows another issue, all these comparisons are based on speculation (I've used a bit of speculation above in how they work) - its not really fair to compare pricing based on speculation ;) On 30 May 2011 01:27, Barry Hunter <[email protected]> wrote: > For what it worth, I dont think it fair to compare a GAE instance like for > like to a VPS. > > they are very different 'beasts'.
