New Update Oracle on Tuesday [13th September 2022] opens a new Cloud Region in Madrid, Spain. This is a part of Oracle’s global plans to operate 44 second-generation cloud regions by the end of 2022.
Now there are a total of 40 regions.
OCI Regions: New OCI Region Added: Madrid, (Spain)
[Updated on September 13th, 2022]
Oracle has announced the availability of a new OCI Region in which you have 1 Availability Domain (AD)

What is Oracle Cloud Regions
- Oracle Cloud Infrastructure (OCI) Servers & Data is hosted in a Oracle Cloud Region.
- There is a total of 40 Region now (i.e. London, Sao Paulo, Frankfurt, Ashburn, Phoenix, Canada, Tokyo, Seoul, Mumbai, Dubai, Zurich, Sydney, Osaka, Melbourne, Jeddah, Amsterdam, Montreal, Hyderabad, Chuncheon, San Jose, Newport, Santiago, Vinhedo, Jerusalem, Marseille & Singapore, Paris, Marseille, Milan, Queretaro, Madrid, Stockholm, Abu Dhabi, Singapore, Toronto etc.).
- 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.
- 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.
Also Check: Oracle Network.
2. Another method is Log into the Console, & from the Navigation menu, under Governance & Administration, click Region Management, there you can Subscribe to other Regions
Also Check: Oracle VPN Connect.
OCI Availability Domain (AD)
- Availability Domain (AD) is one or more data centers located within a region. A region is composed of three availability domains.
- The Availability Domains are interconnected via a low-latency within a region.
OCI Fault Domain (FD)
- Fault Domain is a group of hardware components that all share a common point of failure. To be fault tolerant to a specific level, multiple fault domains are required at that level.
- FDs are physical data centers with availability domains, which provides a higher level of protection from unexpected hardware failures or computer hardware maintenance.
- Each AD (availability domain) have 3 fault domains (FDs).

How A Region, FD & AD Provides High Availability?
- The region is divided into datacentres which are OCI 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 a 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 OCI Availability Domain
OCI 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

OCI Realms
A OCI 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:
- Commercial
- Government
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.
Also, Check Oracle Storage.

FAQ:
Q1: Which is an important consideration when choosing an oracle cloud infrastructure region?
Ans: Choose the region that is in close proximity to end users for the best performance
Q2: How will you configure high availability for an application in an oracle cloud infrastructure region with a single availability domain?
Ans: Setup your application across multiple Fault Domains and the database tier contains Oracle Cloud Infrastructure Database instances. For high availability, use 2-node virtual machine (VM) DB systems or Exadata DB systems.
Q3:What capability protects against failures within an oci availability domain?
Ans: Fault Domains, it provides protection against unexpected failures within AD. Fault domains are physical datacenters with availability domains, FDs are used to reduce hardware failures.
