Today Google announced they have opened up Google Apps so that anyone can signup.  They also released the planned pricing for people who exceed the free quota.  However, they are not yet offering the ability for developers to purchase additional resources.

$0.10 – $0.12 per CPU core-hour

$0.15 – $0.18 per GB-month of storage

$0.11 – $0.13 per GB outgoing bandwidth

$0.09 – $0.11 per GB incoming bandwidth

I am curious how the CPU core-hour is going to be defined.  Will it be like Amazon where it is the time you instance is running whether or not your instance is actually processing anything.  Or will they just charge for the cpu used while processing requests to your application.

Google also announced that a new image manipulation API is available.  This is the same infrastructure that is used for the Picasa Web Albums.  The other new one is the Memcache API which is a high performance caching layer.
