Chapter 6: Understanding Database Choices on Oracle Cloud Infrastructure

Oracle Cloud Infrastructure (OCI) provides a range of database services, and these are categorized as autonomous and co-managed database services. Despite the type of database service, these databases are designed to be robust so that enterprises can use them on a cloud scale. The Oracle Database service is backed by a robust infrastructure and is capable of handling mission-critical production workloads. This includes three availability domains and multiple regions. Currently, active redundancy can be implemented with features such as Data Guard configured to operate across all availability domains.

The networking that backs these database systems, along with every other system in OCI, is fully non-blocking and fully contextualized (multi-tenant with full isolation between networks). Speeds go from a minimum of 10 gigabits up to dual 25 gigabits per host, along with dedicated InfiniBand (IB) for cluster and...
