Overview of Oracle Database Cloud Best Practices

31 Overview of Oracle Database Cloud Best Practices

Oracle Cloud and MAA collaborate closely to enable customer success using the varies Oracle Database Cloud services.

This partnership ensures

Databases, Grid Infrastructure, Exadata, and infrastructure are deployed and configured with MAA best practices in the Oracle cloud.
Cloud life cycle practices such as patching, backup and restore, disaster recovery, and pluggable database management incorporate MAA optimizations as new features and capabilities are introduced into the Oracle cloud.
Oracle owns and manages network, system, and Exadata infrastructure using MAA practices and optimizations.
Oracle high availability and disaster recovery (HA/DR) solutions meet our Enterprise customer standards for Gold and Platinum MAA solutions.

For the latest details, see Oracle Cloud Maximum Availability Architecture.

The following table outlines MAA validated solutions and guidance for Oracle Database Cloud services.
