The Regions of OCI

Let’s talk about the available regions of Oracle Cloud Infrastructure (OCI). A region is a localized geographic area, and an availability domain is one or more data centers located within a region. A region is composed of one or more availability domains.

Oracle now claims to have the widest availability of Cloud Infrastructure. Oracle has 40 regions and planned to open 9 more in years to come. The below map illustrates the available regions:

Most of the regions are single availability domains (AD) or data centers, with each AD having three Faulty Domains (FD), which provide hardware redundancy. Oracle has plans to add multiple ADs in the future based on the raising demand in a particular region. If you observe Oracle have now two or more regions in a single geography. This help to mitigate the high availability of an application in a single geographical region.

Below is the detailed list of available regions in OCI.

The list above is for the Public Cloud Regions, but Oracle also provide Government Cloud Regions. As of now, these regions are only available for USA and UK. The list of regions is as below:

USAUS DoD East (Ashburn)1

With region availability in 22 countries, I can say that OCI is available globalbly. Oracle is working on more regions availablity in key regional markets. Now, Oracle should make multiple ADs available in each of the region. Multiple ADs helps in building better high availabiliy of applications hosted in Cloud.

I hope this post helped you understand OCI Regions and it’s global footprint. I will keep this post updated with upcoming regions and ADs.

I need your help to provide with suggestions and comments to further imporve my blog. Thanks for reading.
