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.
