New Update [24th July 2020] Oracle opens the second US West cloud region in San Jose. This is a part of Oracle’s global plans to operate 36 second-generation cloud regions by the end of 2020.
Oracle on Friday (24th July 2020) added a new Cloud Region in San Jose, CA. Now there are a total of 19 regions.
New Region Added: San Jose, CA
[Updated on July 24th, 2020]
Oracle has announced the availability of a new Region in which you have 1 Availability Domain (AD)
What Is Region
- Oracle Cloud Infrastructure (OCI) Servers & Data is hosted in a Region.
- There is a total of 19 Region now (i.e. London, Sao Paulo, Frankfurt, Ashburn, Phoenix, Canada, Tokyo, Seoul, Mumbai, Zurich, Sydney, Osaka, Melbourne, Jeddah, Amsterdam, Montreal, Hyderabad, Chuncheon, San Jose).
- Every Region can have up to 3 Availability Domain. The first 4 regions (London, Ashburn, Pheonix, and Frankfurt) have 3 ADs while all the new regions have 1 AD each.
- OCI services are Global (IAM), Regional (VCN, Object Storage), and some are AD Specific (Compute, DB System, Boot/Block Volumes).
- When you create a Cloud Account a Home Region is by default allocated to you, wherein you can subscribe to another region as well.
How To Subscribe To New Region
1. Log in to the Cloud Console, & from the taskbar drop down, click on Manage Region, from there you can subscribe to any Region you want.
Note: As of March 2020 if you are using a trial account then you can only subscribe to Home Region.
2. Another method is Log into the Console, & from the Navigation menu, under Administration, click Region Management, there you can Subscribe to other Regions
Availability Domain (AD) & Fault Domain (FD)
- Availability Domain (AD) is one or more data centers located within a region. A region is composed of three availability domains.
- A fault domain is a grouping of hardware and infrastructure within an availability domain, which provides a higher degree of protection from unexpected hardware failures or computer hardware maintenance.
How A Region, FD & AD Provides High Availability?
- The region is divided into datacentres which are Availability Domains. ADs are further divided into Fault Domain & FD provides protection against failure within AD. This Process is an example of High Availability within a Datacentre.
- If you are designing your databases, or VM, or Load Balancer then you will be configuring them within AD but across Fault Domains for High Availability within a Datacenter.
- If you want HA across the regions with single AD and If a region supports multiple ADs then you are going to deploy them across multiple ADs or you can configure them across Region to avoid any region failures.
- In case of a region failure of a single AD region, we will be deploying services across the region to avoid any region failure. This process is an example of Region pair maintaining HA

How To Check The Availability Domain
Availability Domain is one or more data centers located within a Region. Every Region can have up to 3 Availability Domains. The first 4 regions (London, Ashburn, Pheonix, and Frankfurt) have 3 ADs while all the new regions have 1 AD each.
Once you subscribe to the new region, you can go under Compute & try to create an Instance.
Here, you can see, in this new region you will have only 1 AD
Realm In OCI
A realm is a logical collection of regions. Realms are isolated from each other and do not share any data. Tenancy exists in a single realm and can access regions that belong to the realm. Currently, there are 3 realms in OCI:
- Commercial Realm
- Govt Cloud: FedRAMP (Federal Risk & Authorization Management Program)
- Govt Cloud: IL5 Authorized (Impact Level 5)
Note: Not all services are currently supported in Govt Cloud.
Commercial vs Government Region
There are two types of Regions:
a) Government Cloud: Is dedicated to Government Organizations only (Federal compliant). Only government companies can access them with proper approvals, and this will be assigned by Oracle.
b) Commercial Cloud: It is not limited to one Organization but it is publicly available.
