Please don't talk about others such storage, just for the computing.
Please the first post in this thread:

Specially, here I compare your B! backend and amazon Small Instance.
B1 128MB 600MHz $0.08 per hour
Amazon Small Instance: 1.7 GB, 1.0-1.2GHz, 160 GB of local instance
storage, $0.085 per hour.
Assume the startup memory usage is 30M vs. 1000M, so the free memory
for app to use is: 98M vs 700M.
(here assume 1000M EC2 startup memory includes the memcache memory)
The $/(per M memory for apps)/(per GHz GPU)/(1000 hours) is $1.36 vs
$0.12.
You charge more than 10 times than EC2.
Why?
