OCI & Database Service….

• Oracle offers database cloud services in a range of public cloud deployment choices:
  • Fully automated database service tuned and optimized for transaction processing or Data Warehousing with Oracle Autonomous Database
  • Virtualized and bare metal databases with Database Cloud Service
  • Databases running on world class engineered infrastructure with Exadata Cloud Service
• Oracle also offers Cloud At Customer for customers who want Exadata database cloud services behind their firewalls, on their own premises.

Oracle Cloud Infrastructure (OCI) takes advantage of high-scale, high-bandwidth networks that connect cloud servers to high-performance local, file, block, and Object Storage to deliver a cloud platform that yields the highest performance for traditional and distributed applications, as well as highly available databases.

OCI offers the ability to run everything from small VMs to large bare metal clusters and highly available databases on the same isolated networks, accessible through the same APIs and console, allowing apps to have direct, low-latency access to high-performance DBs running on physical servers in the same infrastructure.

OCI has a number of architectural design optimizations that are geared to run Oracle’s databases with unmatched scalability and reliability. For example, Oracle Cloud Infrastructure is optimized for Oracle 18c, Oracle Real Application Clusters (RAC), as well as deep integration with Oracle Engineered Systems such as Oracle Exadata.

Optimized to run Oracle databases, benchmarking results show Oracle databases run faster than others, so customers get data-driven results faster and at a lower cost with Oracle.

As a leader in data management and technology, innovations such as Oracle Real Application Clusters (RAC), Exadata, and Active Data Guard (ADG) for Oracle DB deliver scale, availability, and reliability that are requirements for high-performance applications. These features aren’t available from our competition, where scaling up database CPUs requires down time and can interrupt business operations and, ultimately, the end-user experience.

OCI is specifically architected for database service.

OCI and OCI Database Services

OCI database service runs on top of OCI, which specializes in bare metal servers, off-box networking (which accommodates any workload, engineered system, VM, or bare metal host all on the same network) and high-speed storage.

OCI Robust Infrastructure

• Three Availability Domains: Multi-region architecture, currently three with a fourth region being brought up
• Fully redundant and nonblocking networking fabric accommodating up to 2 * 25 Gbe networking to the hosts
• Three-way mirrored storage (optional two-way mirroring) for database systems. Disk management set up by OCI Database Service is according to best practices, so ASM comes pre-configured for each of the shapes.
• Redundant InfiniBand fabric for cluster networking (Exadata, 2 Node, bare metal, RAC)

Robust Database Options

• Database RAC Option for both VM and bare metal shapes
• Automatic backups to object storage are set up for users when the database is started. Automated DataGuard configuration for both primary and standby system (available within the AD and across AD)
• All the systems are created so that they follow the maximum availability architecture (MAA). This is considered a certified deployment.
