Cloud services
Cloud services that are privately owned and those that are publicly available
from managed service providers provide standardized computing resources
from pools of homogeneous servers. If a consumer requires more or less
server capacity, the servers are provisioned from or returned to the pools.
This paradigm typically also includes consumer self service, and usage
metering with some form of show back, charge back, or billing.
Analytics
Distributed databases and extensive use of data mining, or analytics, is
another use case that is increasing in prevalence and is being applied to a
greater range of business and technical challenges.
