Oracle Cloud Infrastructure (OCI), the cloud computing service of Oracle Corporation, provides compute, storage, and networking services through its data centers in 22 countries and 34 locations around the world. Growth in Oracle Cloud regions and the company’s core products and platforms, such as Oracle Autonomous Database, MySQL HeatWave, Java, and Oracle Middleware, are driving the company’s need for more data center capacity.
In total, Oracle Cloud operates or is developing 57 data centers around the world. These data centers support Oracle’s current and planned 49 cloud regions – a physical location where it clusters data centers – that are highly available, fault-tolerant, and very unlikely to fail simultaneously.
Oracle Cloud Infrastructure (OCI) typically charges a prepaid fee that gradually decreases as its OCI services are consumed by a customer over a defined time period. For the latest quarter, Oracle’s Cloud Revenue, which includes IaaS and SaaS, reached $3.6 billion, an increase of 45% year-over-year. Therefore, on an annualized basis, Oracle Cloud produces $14.4 billion of revenue.
Dgtl Infra reviews Oracle Cloud’s regions, availability zones, and data centers which support its rapidly growing cloud computing business, with a focus on the company’s existing infrastructure locations and where future deployments will be built.
How Many Data Centers Does Oracle Cloud Have?
Oracle Cloud currently has 40 regions in operation and a further 9 under development, meaning that the company will have a total of 49 regions available in the near-term.
Each Oracle Cloud region is composed of 1 to 3 isolated and physically separate data centers with distinct physical infrastructure (i.e., power, cooling, and networking), known by Oracle as availability domains, and commonly referred to by other cloud service providers as availability zones. These availability domains within the same region are connected to each other by a low-latency, high-bandwidth network.
Ultimately, Oracle plans to establish at least two geographically distributed cloud regions in every country where it operates. To this end, in the United States, Canada, United Kingdom, France, South Korea, Japan, Brazil, India, Australia, and United Arab Emirates (UAE), Oracle already has established two separate cloud regions.
Presently, Oracle Cloud has 48 availability domains in operation and a further 9 under development, meaning that the company will have a total of 57 availability domains existing in the near-term.
Because availability domains are isolated from each other, they are fault tolerant, and very unlikely to fail simultaneously. Furthermore, given that availability domains do not share infrastructure – such as power and cooling, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
Oracle Cloud Regions and Availability Domains
Below is an illustration of the layout of an Oracle Cloud region, which has three availability domains.
Oracle Cloud’s availability domains make it possible for customers to provide high-availability connectivity to the internet and on-premise, and to build replicated systems in multiple availability domains for both high-availability and disaster recovery.
Benefits of Oracle Cloud
Oracle Cloud Infrastructure (OCI) offers customers high-performance, scalable, cost-effective and secure infrastructure that is designed to be rapidly deployable and provide real-time elasticity. Simultaneously, Oracle Cloud enables customers to reduce the amount of time and resources normally consumed by IT processes within on-premise data centers.

Customers use Oracle Cloud to build and operate new cloud-native applications, run new workloads, and move their existing Oracle or non-Oracle workloads to Oracle Cloud from their on-premise data centers or from other cloud-based IT environments.
To this end, Oracle Cloud is designed to be differentiated from other cloud service providers (CSPs) by providing better security and separating cloud control code computers from customer data compute nodes.

Oracle Interconnect for Azure
Beyond Oracle Cloud’s 40 operational regions, the company also has a partnership with Microsoft Azure to enable joint customers to run workloads across the two clouds, through Oracle Interconnect for Azure.
Oracle Interconnect for Microsoft Azure extends Oracle Cloud’s own cloud infrastructure via private, low-latency connectivity to 12 Azure Interconnect regions, which provide organizations with a migration path to a multi-cloud environment. As such, organizations can deploy cloud workloads on both Oracle Cloud and Microsoft Azure for various business and technical purposes.
Cross-cloud connectivity offered by Oracle Interconnect for Microsoft Azure is available in the following regions:
|Oracle Cloud||Microsoft Azure|
|US East (Ashburn)||East US (Richmond)|
|UK South (London)||UK South (London)|
|Canada Southeast (Toronto)||Canada Central (Toronto)|
|Netherlands Northwest (Amsterdam)||West Europe (Amsterdam)|
|Japan East (Tokyo)||Japan East (Tokyo, Saitama)|
|US West (San Jose)||West US (San Francisco)|

How Does Oracle Cloud Select a Data Center Location?
Oracle Cloud selects a data center location using a number of site selection criteria, including environmental threats, power availability and stability, vendor reputation and history, neighboring facility functions (e.g., high-risk manufacturing or high-threat targets), and geopolitical considerations.
At these locations, Oracle Cloud builds data center facilities using steel, concrete, or comparable materials, with a design made to withstand an impact from a light vehicle strike.
READ MORE: How Much Does it Cost to Build a Data Center?
Data centers housing Oracle Cloud services use redundant power sources and maintain generator backups to prevent widespread electrical outages. Additionally, server rooms are monitored for air temperature and humidity, and fire suppression systems are in-place.
In terms of connectivity, Oracle Cloud regions and availability domains protect data privacy for cloud network traffic transiting to other Oracle Cloud data centers via its network backbone. In particular, this protection is enabled by private, dedicated wide area network (WAN) fiber-optic connections. As such, fiber connectivity is a major consideration in Oracle Cloud selecting a data center location, with a focus on latency limits and distance to nearby points-of-presence (PoPs) or network access points (NAPs).
Oracle FastConnect – Cloud On-Ramp
Oracle FastConnect is Oracle Cloud’s term for a cloud on-ramp, which allows customers to connect directly to their Oracle Cloud Infrastructure (OCI) virtual cloud network via dedicated, private, high-bandwidth connections. Specifically, this service delivers:
- Network connectivity alternative to the public Internet
- High bandwidth options
- Better and predictably lower network latency
- Dedicated and private connection to Oracle Cloud Infrastructure (OCI) resources
One of the most common reasons for using Oracle FastConnect is for a customer to link its on-premise data center with Oracle Cloud to run mission-critical applications.
Once connected, customers can choose an appropriate port speed, ranging from bandwidths of 1 gigabit per second (Gbps) to 10 Gbps, and pay a consistent, low price each month.
Customers can connect to Oracle Cloud using a FastConnect partner, a third-party network service provider, or from within a colocation data center.

In a third-party network service provider or colocation data center scenario, a cross-connect is the physical cable that connects a customer’s existing network to Oracle in the FastConnect location.
