Each architecture used to achieve highly available database services is differentiated by the levels of
uptime it offers. These architectures can be grouped into three main categories:
• Data Replication.
• Clustered & Virtualized Systems.
• Shared-Nothing, Geographically-Replicated Clusters.
As illustrated in the following figure, each of these architectures offers progressively higher levels of
uptime, which must be balanced against potentially greater levels of cost and complexity that each can
incur. Simply deploying a high availability architecture is not a guarantee of actually delivering HA. In
fact, a poorly implemented and maintained shared-nothing cluster could easily deliver lower levels of
availability than a simple data replication solution.
