Regions
An Oracle Cloud Infrastructure region is a localized geographic area that can be separated from other regions by vast distances across countries and continents.
Your cloud account has a home region, and you can subscribe to additional regions. The Oracle Cloud Infrastructure Console shows both subscribed and unsubscribed regions.
Know these components of regions:
- Region Infrastructures - Regions contain physical data centers. Some data centers contain the first generation of Oracle Cloud Infrastructure (generation 1 or Classic), whereas most data centers contain the second or later generations of Oracle Cloud Infrastructure (generation 2). Fusion Analytics instances exist in generation 2 regions and Oracle Fusion Cloud Applications instances exist in both generation 1 and 2 regions.
- Cloud Realms - Oracle Cloud regions are organized into separate cloud realms for
customers with differing security and compliance needs. Realms are isolated from
each other and share no physical infrastructure, accounts, data, resources, or
network connections. Customer tenancies exist in a single realm and can only
access regions that belong to that realm. The following realms are available:
- Commercial Realm - These regions are accessible to any customer. Fusion Analytics instances exist in the commercial realm.
- Sovereign European Union Realm - These regions are separated from the commercial regions and operate entirely within the European Union.
- US Government - These regions are isolated from commercial customers. Multiple realms are certified under different compliance standards for the US government. These regions support regulatory-compliant, mission-critical US public sector workloads.
- UK Government - These regions are designed in collaboration with multiple UK government and defense ministries. These regions are for the UK government and defense customers.
