Discovery One is the name of the ~~cluster~~ of machines ~~hosting~~ activities.sugarlabs.org. Activities.sugarlabs.org is a system for encouraging developers ~~of different skill levels~~ to cooperatively develop, edit, and distribute learning activities for the Sugar Platform.

Discovery One is the name of the group of machines running activities.sugarlabs.org. Activities.sugarlabs.org is a system for encouraging developers to cooperatively develop, edit, and distribute learning activities for the Sugar Platform.

The prime design characteristics of a.sl.o are scalability and availability. As the a.sl.o ~~userbase~~ grows, each component can be scaled horizontally, across multiple physical machines.

The prime design characteristics of a.sl.o are security, scalability and, availability. As the a.sl.o user base grows, each component can be scaled horizontally, across multiple physical machines. The additional physical machines will provide room for VMs to provide redundant services

As of November 2009 activities.sl.o is ~~server~~ 500,000 activities per month using two machines located at Gnaps. The proxy(green) is on treehouse and the rest(red) is on sunjammer.
