4. 1.Strong Capacity No-limited bandwidth For example: 1M (bits) server bandwidth 300K bytes web page (html, image, and text,etc.) (300K(bytes) x 8 ) / 1M (bits) = 2.34375 seconds 100people: 234.375 seconds (about 4 minutes) timeout: 180 seconds Network congestion?
5. Actual Measurement 10M (bits) client bandwidth Iperf : about 1M bits/sec in Taiwan or 5.6M in US

9. 5.High Portability Google app engine AppScale AppScale is a platform that allows users to deploy and host their own Google App Engine applications. It executes automatically over Amazon EC2 and Eucalyptus as well as Xen and KVM. It has been developed and is maintained by the RACELab at UC Santa Barbara. It supports both the Python and Java Google App Engine platforms.
