Oracle Maximum Availability Architecture (MAA) provides architecture, configuration, and life cycle best practices for your Oracle Database to meet your high availability service levels for Oracle databases residing in an on-premises, Oracle Public Cloud, Cloud@Customer, Multicloud (DB@Azure, DB@AWS, and DB@Google Cloud), or hybrid database architecture consisting of both on-premises and cloud databases.

For high availability, data protection, and disaster recovery, Oracle MAA offers a choice of standard MAA reference architectures: Bronze, Silver, Gold, Platinum, and Diamond. Each MAA reference architecture, or high availability tier, uses an optimal set of Oracle capabilities that, when deployed together, reliably achieve target service levels for unplanned outages and planned maintenance events.

Oracle MAA uses Chaos Engineering throughout its testing and development life cycles to ensure that end-to-end application and database availability is preserved, or at its optimal levels, for any fault or maintenance event. Chaos Engineering is the discipline of experimenting on a system in order to build confidence in the system's capability to withstand turbulent conditions in production. Specifically, MAA introduces various faults and planned maintenance events to evaluate application and database impact throughout our development, stress, and testing cycles. With that experimentation, best practices, defects, and lessons learned are derived, and that knowledge is put back into practice to evolve and improve our MAA solutions.

Every database needs to run on a reliable system platform to meet the expected RTO and RPO goals. Oracle Exadata Database Machine is engineered to be the highest performing, most secure, and most available platform for running Oracle databases, and is required for the MAA Platinum and Diamond architectures.

Monitoring databases and systems is critical to proactively detect, prevent, and recover from issues before they have an availability impact. Oracle Enterprise Manager Cloud Control is Oracle's MAA strategic monitoring platform.

Oracle Cloud works collaboratively and continuously with Oracle MAA to incorporate all of the MAA reference architectures, configuration best practices, and life cycle operations. Oracle Cloud and MAA evolution go hand-in-hand, delivering a fully Oracle-managed MAA solution with all cloud database services, including Autonomous Database.
