typesclustering
shared Cluster
A cluster of servers/blades that is
shared by many applications or database
tenants.
shared Instance
A single database instance across a cluster that runs
multiple database schemas on behalf of multiple application tenants.
dedicated Cluster
Some applications will be large enough to use a
dedicated portion of the hardware environment.
They share the same components and capacity.
typescloud
The infrastructure for
implementing the cloud is controlled completely by the
enterprise.
Typically, private clouds are
implemented in the enterprise’s data centre and
managed by internal resources.
External organizations provide the
infrastructure and management required to
implement the cloud.
Applications and storage are made
available over the internet and can be free or offered at
a pay-per-usage fee.
To meet the benefits of both approaches,
newer execution models have been developed to
combine public and private clouds into a unified
solution.
