Oracle Cloud Infrastructure (OCI), the cloud computing service of Oracle Corporation, provides compute, storage, and networking services through its data centers in 24 countries and over 40 locations around the world. Growth in Oracle Cloud regions and the company’s core products and platforms, such as Oracle Autonomous Database, Fusion applications, 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 63 data centers around the world. These data centers support Oracle’s current and planned 53 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 IaaS revenue reached $1.8 billion, an increase of 49% year-over-year. Therefore, on an annualized basis, Oracle Cloud produces $7.2 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 48 regions in operation and a further 5 under development, meaning that the company will have a total of 53 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. Within the same region, these availability domains are interconnected by a low-latency, high-bandwidth network.

Over the coming years, Oracle plans to build 100 new cloud data centers to meet “billions of dollars” in excess contracted demand that exceeds its current capacity, which is constrained by data center space, power requirements, and GPU availability.

Ultimately, Oracle plans to establish a minimum of two geographically distributed cloud regions in every country where it operates. At present, it has already established two separate cloud regions in each of: the United States, Brazil, Canada, Chile, Mexico, the United Kingdom, France, Germany, Spain, South Korea, Japan, India, Australia, and the United Arab Emirates (UAE).

Availability Domains

Oracle Cloud has 58 availability domains in operation and a further 5 under development, meaning that the company will have a total of 63 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 allow customers to ensure high-availability connectivity both to the internet and on-premises. Additionally, they can build systems replicated across multiple availability domains, catering to both high-availability and disaster recovery needs.

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.

Oracle Servers that are X7-2 x86 and Secure Reliable Performances

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 differentiates itself from other cloud service providers (CSPs) by offering enhanced security and by separating cloud control code computers from customer data compute nodes. Most notably, Oracle Cloud competes for customers with the following CSPs: Amazon Web Services (AWS), Microsoft Azure, Google Cloud, and Alibaba Cloud.

Importantly, Oracle Interconnect for Azure offers zero data ingress/egress charges, which can provide organizations significant cost savings when transferring data between the two cloud service providers (CSPs).

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 centers using materials such as steel and concrete. The facility design is intended to withstand the impact of a light vehicle strike.

Oracle Cloud Selection Criteria for a Data Center Location with Map of the World

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 in several ways: using a FastConnect partner, through a third-party network service provider, or directly from within a colocation data center. Below are diagrams illustrating the two primary methods for connecting to Oracle via FastConnect:

Oracle FastConnect with Partner or Third-Party Provider

Oracle FastConnect with Colocation

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.
