Understanding of Oracle Cloud Infrastructure

Oracle Cloud Infrastructure is a complete cloud infrastructure platform for all workloads. OCI offers a high-performance compute and storage capacity in a flexible overlay virtual network which you can securely access from on-prem NW also.

Below picture shows the complete set of services offered by Oracle Cloud infrastructure:

OCI Global Cloud Data Center

Oracle offers more than 80 cloud infrastructure and platform services. Most regions also offer a Cloud Application (SaaS) portfolio.

Across Applications and Infrastructure, with public and hybrid cloud options, Oracle supports local access, regional compliance, and true business continuity.

Find the complete list of OCI regions on this link:

About Region, AD & FD

Region: A region is a localized geographic area. Regions are independent of other regions and can be separated by vast distances—across countries or even continents

Availability Domain (AD0: An availability domain is one or more data centers located within a region. A region is composed of one or more availability domains. Few regions contain three availability domains and a few other regions contain a single availability domain.

Fault Domain (FD): A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains.

The below diagram represents the relationship between Region, AD, and FD.
