Oracle Exadata Cloud service Hybrid Cloud,multi cloud with private cloud

Oracle Exadata Cloud Service delivers the world’s most advanced database cloud by combining the world’s #1 database technology and Exadata, the most powerful database platform, with the simplicity, agility and elasticity of a cloud-based deployment.

Service Overview

Customers can choose to deploy Oracle Database 11g Release 2 (11.2.0.4), Oracle Database 12c Release 1 (12.1.0.2), Oracle Database 12c Release 2 (12.2.0.1), Oracle Database 18c, Oracle Database 19c, or a combination of these. Customers connect to databases from their applications using standard Oracle Net Services clients such as JDBC and OCI. As shown in Figure 2, Exadata Cloud Service also includes all capabilities of the underlying Exadata platform.

Customers can choose an entry level Base System which is not expandable or subscribe to the Exadata Cloud Service X8M. The X8M shapes start with a Quarter Rack and allow elastic expansion by adding additional database and storage servers to enable higher compute and storage capacity. Detailed specifications for Exadata Cloud Service configurations are provided in Table 1.

The database servers have a physical maximum number of compute cores (OCPUs) that can be enabled for the chosen configuration, and customers can specify their desired number of compute cores within these limits. Service pricing is based on the amount of infrastructure dedicated to the service and the number of enabled compute cores.

Elastic Server Expansion and OCPU Scaling

Exadata Cloud Service features infrastructure that is dedicated to each customer, to ensure that response times and throughput are predictable for critical business processes. Exadata Cloud Service X8M allows online elastic database and storage server expansion, supporting workloads of different sizes. In addition, Exadata Cloud Service also allows OCPU scaling, enabling customers to grow, and later shrink, their individual database server OCPU resources to meet their peak or seasonal demands.

Customers who purchase universal credits pay the same low rate for the service when they elastically scale their service.
This provides them with the best of both worlds; Low prices based on Oracle's universal credit pricing model, with the flexibility to adjust capacity as business conditions change.

ACCESS AND SECURITY
Exadata Cloud Service provides secure high-performance access from both on-premises systems and from other Oracle Cloud Infrastructure services.
To ensure consistent high-performance and isolation, multiple separate networks are provided on each Exadata server.

* The Client and Backup Networks provide 25 Gb/sec connectivity for high-bandwidth use cases such as application connectivity, backup, data loading, and disaster protection using Data Guard.

* RDMA over Converged Ethernet (RoCE) internal network fabric is used internally for ultra-high-speed compute-tocompute and compute-to-storage networking.

* A secure, separate and isolated Cloud Management network is used by Oracle Exadata Cloud Operations to manage the servers, storage and switches.
