1.1 Regions, Availability Domains
Oracle Cloud Infrastructure (OCI) is hosted in Region and Availability Domain. Region is a geographical area and Availability Domain is a data center located in one region. A single Region consists of one or more Availability Domain.
Availability domains are separated from each other so that they are not affected by defects at the same time or by defects in other Availability domains.Availability Domain is designed so that it does not affect other Availability domains because it does not share resources such as power, cooling and internal networks.
All Availability Domain in the Region is connected to Low Latency and High Bandwidth Network between each other to provide mutual high availability.
Region is completely independent of other regions, and in case of obstacles that may occur in the regime, each region is composed of a distant position of another or other continents, and may use other Regions’ services according to various requirements.
- Risks that can occur in regime units, that is, meteorological dysfunction, earthquake, etc.
- In order to meet legal issues or other different businesses
