What is Oracle Public Cloud

Cloud computing

Oracle combines its cloud offerings under the Oracle Cloud. Under this umbrella, the group is trying to put together a comprehensive portfolio to serve the entire cloud stack. In addition to SaaS solutions for HCM, ERP, CX, SCM and EPM, the area of ​​Data-as-a-Service (DaaS), that is Oracle's core discipline, plays a special role.

Oracle's cloud strategy is based on two goals:

  • consistency: In the future, every Oracle software should also be available as a cloud service.

  • Hybrid: On the basis of a standard defined by Oracle, customers should be able to operate all Oracle cloud offerings without restrictions in both the public and private cloud and thus be able to move workloads seamlessly.

To actively support the hybrid strategy, Oracle presented the Private Cloud Machine. This is a physical server on which the identical IaaS and PaaS stack is located that Oracle also uses in its public cloud. The private cloud machine is installed in a customer's own data center and managed and continuously updated in a managed private cloud model from Oracle.

Oracle Cloud: Infrastructure-as-a-Service

Oracle has been on the market with an Infrastructure-as-a-Service (IaaS) offer since 2014. The cloud services are delivered via 19 data centers distributed around the world. For the German market, Oracle operates two data centers in Germany, a primary one in Frankfurt and a backup data center in Munich, which enables geo-redundancy to be set up within Germany. However, it should be noted that not all Oracle cloud services are currently provided from a German data center.

The infrastructure is based on various technologies, including OpenStack, Nimbula (an Oracle acquisition for cloud management in 2013), Linux, the XEN hypervisor and Docker.

As part of its IaaS offering, Oracle focuses exclusively on providing basic infrastructure services. This includes:

  • Computing power (elastic compute)

  • Storage space (Elastic Block Storage, Elastic Object Storage)

  • Network

  • Security (Secure Identity)

These resources are not accessed in the typical self-service mode of a public cloud. Instead, the offer (currently only storage) can be tried out in a 30-day free trial.

The infrastructure resources are controlled either on the basis of a REST API, the Python-based command line or a graphical web interface. Virtual machines can be ordered in self-service and can be provided with images preconfigured by Oracle. Your own virtual infrastructure is secured using lists and rules that control network access to the individual instances. On the other hand, using firewalls with which groups of objects can be formed in order to control access to several resources at the same time or to isolate them.

  1. Oracle Cloud Service Portfolio
    Oracle tries to offer its customers a range of services both in terms of height and breadth.
  2. Oracle Enterprise Cloud Manager
    The Oracle Enterprise Manager Cloud Control provides administrators with an overview of their infrastructure landscape.
  3. Oracle IaaS
    Oracle's IaaS offer consistently focuses on compute, storage, network and security.
  4. Oracle deployment
    Oracle wants to offer its customers the choice of which cloud model is right for them.
  5. Oracle Integrated Cloud
    With the Integrated Cloud, Oracle is trying to integrate its cloud service portfolio.
  6. Oracle PaaS
    Oracle interprets its PaaS differently than the competition and offers further solutions via a programming environment, for example for collaboration.

Oracle offers two types of computing power - Compute and Dedicated Compute. These differ as follows:


  • Aimed at specialist departments and users of test and development environments

  • Shared physical infrastructure

  • Guaranteed capacity for 50 and 100 cores

  • Isolation is based on resource management across the various customer environments.

Dedicated Compute

  • Aimed at large companies

  • Each customer receives their own dedicated physical environment

  • The required performance can be planned

  • Capacities for 500, 1000, 1500 and 2000 cores are available

  • Complete network isolation from other customers

  • Exclusive site-to-site VPN between the Oracle Cloud and your own environment

The infrastructure resources are typically accessed via the Internet. Using a cross-connect connection via partner offers such as the Equinix Cloud Exchange, direct connections can also be established between the company network and the Oracle Cloud infrastructure.

Oracle's infrastructure offering focuses exclusively on infrastructure resources and neglects platform and value-added services. Therefore, it can hardly compete seriously with the leading public cloud providers at the moment. Oracle's main focus is therefore increasingly on the platform level, for which the infrastructure offer forms the basis. Other target groups, such as developers, should also be addressed.
