Denis How do you know gae memcache is not part of 128 Mb? May be it is How do you know how much memcahce is available to your app, is it documented?
If you look at http://code.google.com/p/memcached/wiki/NewOverview, which is one alternative for aws, you do not need to replicate cache across all instances If you look at large aws instance it has 7.5 Gb of memory, 4 processors and 850 Gb of space for 34 cents Even if you take .5 Gb for memcache, which is more than enough you still have 7Gb of RAM left http://aws.amazon.com/ec2/instance-types/ On May 31, 3:03 am, Denis Volokhovskiy <altitudebre...@gmail.com> wrote: > - "Also remember a GAE instance allows you to handle exactly one > request at a > time." > It is not true for JVM application instance - it handles requests > concurrently. > > Besides, GAE memcache is globally visible to all instances, but in AWS > you need to setup your own per instance or 3rd party thru REST. > If you have 8 instances up, then you'll have to have 8x more memory > for your > caching - separate record for each instance. > Plus, with global cache, you may store temporary flags/signals/locks > etc. > Memcache requests will be faster inside GAE than to 3rd party. > > On May 31, 9:10 am, "Raymond C." <windz...@gmail.com> wrote: > > > > > > > > > By "GAE provides you much more", you mean much more *limitation* right? > > > The cost on setup is trivial for a long run application when compared to the > > hosting cost.
