Data center(s)

The high availability system architecture's foundation is underlying in the data center(s) used for deployment of Oracle SOA Suite components. Usually, most implementations are single, physical sites but it is highly recommended that for a medium to large deployment you create at least two logical sites within a data center to get the highest possible availability uptime for your business services. The availability uptime SLAs for 99.999 percent requires that the system's architecture be designed and deployed with at least two physical sites. If you are designing the system architecture to meet the SLAs of 99.9 percent availability uptime, you are recommended to select the data center that has the redundant network, usually from two independent sources and with at least a secondary power source from on-premise power generators. Data center(s) with two independent power sources are rare to find and are expensive to build or lease.
