We’re in an era where organizations want to take an assertive approach to controlling their cloud infrastructure and data to reduce risk. For regulated enterprises, a cloud solution must comply to governance, regulatory, and data privacy requirements. For public sector organizations, security is paramount. The solution must meet the highest demands of mission-critical classified workloads. Finally, the cloud provider must meet all these requirements while delivering a complete portfolio of modern cloud services to ensure application portability and operational consistency.

Dedicated cloud is a continuum, spanning on-premises public cloud to global network edge cloud. Isolated cloud is generally described as air-gapped private cloud solutions that you can fully disconnect from outside network access but have the full breadth of services available in the public cloud.

At Oracle, we’re excited about building this next generation of cloud. Customers and partners have reacted positively as they see the potential of Oracle Cloud Infrastructure (OCI)’s distributed cloud strategy because it satisfies their business, regulatory, and performance requirements while retaining full fidelity of the public cloud.

The on-premises public cloud paradox 

Most customers find themselves in a challenging situation when it comes to dedicated and isolated clouds. Everyone wants the full breadth of public cloud services, but they need the assurance that their confidential information is untraceable in the public cloud. They also want on-premises cloud services to be truly independent of the cloud provider’s public regions and not bounded by factors, such as disconnection tolerance, short- or long-term.

No other cloud provider has been able to meet these needs. Oracle provides a fully disconnected solution with a complete set of infrastructure-, platform-, and software-as-a-service (IaaS, PaaS, and SaaS) solutions without any degradation of services. Executive leaders shouldn’t be forced to make unacceptable trade-offs between business needs, mission critical needs and functionality.

OCI Dedicated Region

OCI Dedicated Region, or Oracle Dedicated Region Cloud@Customer, is a complete OCI cloud region in your data center. OCI Dedicated Region isn’t a shared part of anything or a watered-down version of something else. Data is under your control and never leaves the data center without your permission. You retain full control of your data (and even metadata) to meet the highest security, regulatory, and data residency requirements while modernizing your infrastructure.

Other offerings claim “similar to public cloud,” but similar doesn’t mean the same. Likewise, some same elements don’t add up to the “same thing.” Since its introduction, OCI Dedicated Region remains the only solution in bringing all public cloud services on-premises. Vodafone, one of the largest multinational telecom companies, has deployed six OCI Dedicated Regions in its data centers that manage its European IT and network operations. Nomura Research Institute, one of the most stringently regulated enterprises, has built a service platform and disaster recovery environment on two OCI Dedicated Regions (Tokyo and Osaka) for applications that manage 50 percent of Japan’s stock exchange.

Oracle Cloud Isolated Region

Built to remain disconnected in perpetuity, Oracle Cloud Isolated Region meets the highest demands of mission-critical classified workloads. It doesn’t require connectivity to OCI to manage the infrastructure, services, APIs, or tooling. Other vendors’ air-gapped offerings support a Kubernetes-based environment and provide only a subset of virtual machine (VM) instances, even though most enterprise applications are deployed in VMs.

Have workloads that can only run in non-virtualized environments? Customers’ non-virtualized workloads run on Oracle Cloud Isolated Region because it has dedicated hardware (bare metal instances) to ensure to compatibility or performance needs. Our experts operate our isolated regions and deliver a full set of hyperscale IaaS, PaaS, and SaaS on-premises. It’s dedicated to serving governments and safeguarding global defense missions at hyperscale.


Oracle is committed to helping customers operate globally in a fast-changing environment. With OCI’s distributed cloud, customers are free to deploy workloads wherever they like, even across multiple clouds, with the benefits of cloud innovation and greater control over data residency, locality, and authority. No other cloud provider comes close to delivering such a broad set of cloud services.
