Introduction to Oracle Dedicated Region Cloud@Customer (DRCC)

Over the past few years, the public cloud adoption has become mainstream and the enterprises take advantage of the cloud in term of cost reduction, agility, flexibility, automation and self-service activities.

But it exists a large portion of critical workloads that due to regulatory and performance-related contraints, cannot currently be moved to the public cloud. To solve those restrictions, Oracle has engineered a unique solution named Oracle Dedicated Region Cloud@Customer (DRCC).

Designed as alternative to the OCI public cloud, it offers the same services at the same conditions available on the OCI public regions, inside the customer’s data center.

The main use cases for the DRCC adoption are associated to the following constraints:

  1. Data Sovereignty
  2. Security and Control
  3. Network Latency

Data Sovereignty

Data sovereignty generally refers to government efforts to prevent their citizens’ data from falling into the wrong hands via measures that restrict how businesses can transfer personal information beyond their country’s borders. Those measures can be in the form of regulations—think General Data Protection Regulation (GDPR) in the European Union, which regulates data privacy in the European Union and the European Economic Area as well as the transfer of personal data from those regions, or the California Consumer Privacy Act (CCPA), which gives citizens the right to know what personal information companies collect about them and how it is used and shared.


Security and Control

Restricting the physical access to the data center to special granted employees, and keeping the data behind the company’s firewall.

Network Latency

Specific applications (like trading or Voice over IP) are very sensitive to the increase of the network latency, therefore cannot be easily relocated to the public cloud.

DRCC Overview

As previously mentioned, the DRCC implementation offers the same services at the same conditions available on the OCI public region, for a full list of OCI services and associated SLA please check this link.

The main differences between the DRCC and the OCI region are:

  • It is built inside the customer’s premises
  • Data never leaves the customer’s premises
  • The infrastructure is remotely managed by Oracle
  • All resources are dedicated to one tenant

DRCC Benefits

Oracle Dedicated Region Cloud@Customer brings all public cloud capabilities on-premises, so the enterprises can reduce infrastructure and operational costs, upgrade legacy applications on modern cloud platform, and meet the most demanding regulatory, data residency and latency requirements:

  • Bring all existing OCI services (at the time of this blog post around 80) including the Autonomous Database, eliminating any technical debt.
  • Leading cloud performance
  • Security-first architecture that reduces the risk and attack surfaces
  • Keep full control of all data to meet the most demanding data privacy and latency requirements.
  • Pay only for the services consumed and during the utilization period.
  • Deploy seamlessly between on-premises and public cloud, using the exact same tools, APIs, and SLA available in OCI and DRCC.
  • Single-vendor cloud accountability and management for all cloud platform, database, and infrastructure


Oracle DRCC unique characteristics offers cloud-scale security, resiliency and superior performance, allowing to meet the most stringents requirements in terms of data residency and latency.

DRCC expands the public OCI offers, enabling customers to build and operate modern applications inside their data center at the same price offered in Oracle’s public cloud.

Oracle Cloud Computing

What is a database Cloud Computing?

This looks like the million dollar question; what we know for sure is that it is a quite recent technology and different people identify the Cloud Architecture by different key features (On-Demand, Broad Network Access, Resource Pooling, Rapid Elasticity, Measured Service). There are two main categories: Private and Public Cloud, which identifies respectively in house and outsourced Cloud installation. Focusing on Oracle Database technology the Private Cloud is a clustered infrastructure hosted on the company?s data center, therefore the IT department is responsible of the installation, maintenance and life cycle of all hardware and software components. In case of Public Cloud the company demands the management of the databases to a third party, which owns the infrastructure used to manage the databases of different customers.

Beyond the different marketing definitions of database cloud computing, Oracle provides a reach set of features to realize this kind of setup. The main component of this architecture is the Grid Infrastructure, which provides the cluster and storage foundation of Oracle Cloud Computing. On top of the Grid Infrastructure we have the RDBMS which enables RAC, RAC One Node and stand-alone database setups.

At this point, anyone can say that with the exception of the name, there is almost nothing new compared to the earlier version of Oracle Real Application Cluster (RAC). But Oracle Cloud Computing is much more than a simple multi-node RAC which hosts several databases; the introduction of features like Quality of Service Management (QoS), Server Pool, Instance Caging (extension of Resource Manager) and the enhancement of the existing ones, allow to consolidate all the environments guaranteeing to each application: the performance expected, the scalability for future needs, the availability to respect the Service Level Agreement (SLA), the best time to market, the governance of the entire platform and last but not least cost saving.

Obviously Oracle provides all the instruments to reach such great result, but it is up to the single organization to define and implement the most appropriate modus operandi in terms of OM, Life Cycle, Capacity planning and management, to obtain the result promised by this great technology.
