OCI Regions
Oracle Cloud Infrastructure (OCI) regions are essential to Oracle’s public cloud, providing a globally distributed network that supports secure and high-performance cloud services.
Here’s a detailed overview:
- Global Distribution: Oracle Cloud Infrastructure is available globally, with services from 48 public cloud regions in 24 countries. This extensive network ensures that organizations can access Oracle’s cloud services from various locations worldwide.
- Secure and High-Performance Local Environments: Each OCI region is designed to provide secure and high-performance environments, enabling organizations to move, build, and run all workloads and cloud applications. These regions comply with regional data regulations, ensuring data sovereignty and security requirements are met.
- Organized Cloud Realms: OCI regions are organized into separate cloud realms to cater to customers with different security and compliance needs. These realms are isolated, with no shared physical infrastructure, accounts, data, resources, or network connections. Customer tenancies exist within a single realm and can only access regions, ensuring the security and integrity of data and operations.
- Geographical Separation and High Availability: The regions in different cities operate on distinct power grid network infrastructures and are located in areas that consider geographic natural disaster risks. Each region has at least three fault domains (FDs) to ensure the high availability of applications and databases. These FDs provide anti-affinity, allowing for the distribution of instances across different physical hardware. In some regions, multiple availability domains (ADs) are also available for even higher availability, albeit with slightly higher latency.
- Business Continuity and Disaster Protection: Deploying applications and replicating data across at least two OCI regions enhances business continuity and disaster protection. Countries like the US, Canada, the UK, France, South Korea, Japan, Brazil, India, the UAE, and Australia already have multiple cloud regions. Oracle continuously expands its network to include more regions worldwide, supporting diverse business needs and regulatory compliance.
- Interconnected Regions and Encrypted Traffic: Each OCI region is interconnected with others through a private, redundant, Oracle-managed backbone. This network provides 10 TB per month of outbound bandwidth at no cost and offers competitive prices for additional bandwidth usage. Furthermore, traffic between regions and between availability domains is encrypted, ensuring secure data transfer and communications.
Regions by the end of 2023.
- North America: 13 regions
- South America: 5 regions
- Europe: 15 regions
- Middle East & Africa: 5 areas (with three more coming soon)
- Asia Pacific: 9 areas (with one more coming soon)
Oracle OCI Security
Oracle Cloud Infrastructure (OCI) provides robust security features to ensure the safety and integrity of cloud services and data. Its security model is based on several core pillars:

- Usage Flexibility: Credits can be used for any eligible OCI service in any region, allowing customers to change service usage as needed. This model encourages experimentation with different services without long-term commitments.
- Cost Efficiency: Customers purchasing under this model receive discounts on OCI service prices. If the annual commitment is exceeded, Oracle invoices monthly for excess usage at established rate card pricing. Unused credits by the end of the contract term are forfeited.
Pay As You Go (PAYG) and Annual Flex
- PAYG: This model is billed in arrears based on actual usage. It offers flexibility, especially for fluctuating or unpredictable usage patterns.
- Annual Universal Credit: Customers prepay for a certain number of credits for at least 12 months. Unused credits are lost, and pricing is approximately 66% of the PAYG rates. Enterprise clients often choose this model for predictable usage and budgeting.
Additional Pricing Features
- Customer-Friendly Approach: OCI aims to eliminate overpayment and billing surprises with features like flexible computing and lower data egress fees. OCI service prices are consistent across all global regions, including government regions and OCI Dedicated Region.
- Data Egress Fees: OCI offers 10 TB free monthly and charges significantly less for data egress than other providers. This facilitates data transfer across the globe without incurring high costs.
- Oracle Support Rewards: This program helps reduce on-premises technical support costs, reducing $0.25 for every $1 spent on OCI. This incentive is designed to encourage cloud transition for enterprise customers.
- Volume Discounts: Customers who purchase a sufficient number of Oracle Universal Credits are entitled to volume discounts, which maintain the contracted service rate even if credits are consumed before the contract ends.
- Inclusive Technical Support: Base fees for OCI services include enterprise-ready support without extra charges, unlike other providers who may charge additional fees for technical support.
- Financial Management Tools: OCI provides free tools for monitoring and managing spending, including budgets, visualizations, advice, and scheduled cost and usage reports.
- Consistent Global Pricing: OCI charges the same for services in every region, including government regions, providing a consistent performance and cost experience. This consistency also applies to the OCI Dedicated Region and Oracle Alloy.
- Virtual Machine Scaling: OCI virtual machines can be scaled precisely to match workloads, avoiding overpayment for unneeded capacity.
In summary, OCI’s pricing models cater to various customer needs, offering flexibility, cost-efficiency, and predictability.
The combination of PAYG and Universal Credit models, additional incentives, and global pricing consistency make OCI an attractive option for diverse cloud computing requirements.
