33 Overview of Oracle Database Cloud Best Practices

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

This partnership ensures

• Databases, Grid Infrastructure, Exadata, and infrastructure are deployed and configured with MAA best practices in Oracle Cloud Infrastructure, including public cloud, OCI Dedicated Region, Oracle Database@Azure, Oracle Database@Google Cloud, Oracle Daabase@AWS, and Exadata Cloud@Customer.
• 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 Cloud owns and manages network, system, and Exadata infrastructure using MAA practices and optimizations.

  The only exception is in Oracle Multicloud where you can choose to use AWS, Azure, or Google's network between application and database tiers, or network between database tiers for Oracle Data Guard and Oracle GoldenGate architectures. Oracle typically recommends using Oracle "OCI" network between Data Guard configurations to reduce additional network hops.

• Oracle high availability and disaster recovery (HA/DR) solutions meet our Enterprise customer standards for Gold and Platinum MAA solutions.
