Global reach: The ability to reach audiences around the globe. Cloud services can have a presence in various regions across the globe, which you and your customer can access, giving you a presence in those regions even though you may not have any infrastructure in that region.
Predictive cost considerations: The ability for users to predict the costs they will incur for a particular cloud service. Costs for individual services are made available, and tools are provided to allow you to predict the costs a service will incur. You can also perform analysis based on planned growth.

A distinction between scalability and elasticity is that elasticity is done automatically.
