Core Concepts for Oracle Cloud Infrastructure


Oracle allocates you a tenancy when you sign up for Oracle Cloud Infrastructure. A tenancy is a safe and separate compartment that houses all your cloud resources. The name of your Oracle cloud account, which is renewable, is the name of your tenancy.


Another logical idea that aids in organizing and managing access to your cloud resources is the concept of compartments. A compartment is a grouping of connected cloud resources, such as compute instances and cloud networks that individuals with the necessary permissions can access.

Policy Inheritance and Access Control:

Administrators make access policies to regulate access to resources in each compartment. The compartment hierarchy can run up to six levels deep, and all of a compartment’s sub-compartments will inherit any related policies.

Resources Cannot Be Moved Between Compartments Without Restrictions:

Only a selected few resources, including clusters, functions, and policies for Container Engine for Kubernetes, prevent resources from being migrated to another container. It could take some time for dependencies to show up in the new compartment after relocating resources with dependents with other resources. Some resources require the dependencies to be relocated separately. Once relocated, the resource will immediately be subject to the new compartment’s rules.

Regions, Subscriptions to Regions, and Realms:

The location where your Oracle account and IAM (Identity Access Management) resources were initially generated is known as your home region. The home region cannot be altered, although tenancies subscribed to other regions will receive access to the home region’s IAM resources. A tenancy can only be located in one realm, with access to all of the regions in that realm.

Services Provided by Oracle Cloud

IaaS, PaaS, SaaS, and DaaS are four categories in which OCI offers a wide range of services.

  • Infrastructure as a Service

OCI offers bare metal servers, virtual machines, graphics processing units, high-performance computing, and container orchestration as examples of its compute capabilities. For essential storage use cases and workloads, OCI offers a variety of storage solutions, including local, file, object, archive, and block.

The isolated network virtualization notion is at the core of OCI design. The hypervisor’s network is decoupled by OCI’s network virtualization, considerably lowering the security vulnerabilities inherent in most hypervisors.

  • Platform as a Service

The IaaS capabilities from OCI provide the foundation for PaaS, incorporating several open-source frameworks from Oracle. Popular PaaS services provided by OCI include:

  • Application Creation

Where programmers may create, code, test, and publish cutting-edge intelligent apps on the cloud.

  • Software as a Service

Organizations can employ OCI SaaS products as ready-to-use applications for various use cases. They can automate many processes, including financial management, sales and marketing, supply chain management, Enterprise Resource Planning (ERP), and human resources.

  • Data as a Service

Data aggregation is what OCI’s DaaS does. You can use it to access more than 135 million contact data with more than 90 firmographic attributes located worldwide. Organizations can use these data to instantly normalize, standardize, and rectify their contact information. Additionally, DaaS can help these firms make their data accurate and thorough.

Oracle Cloud Infrastructure Core Products Overview

Oracle Cloud Infrastructure offers over 70 cloud services, so that we will cover only the high-level domains.

  • Compute and Containers

Dedicated bare-metal servers, multi-tenant virtual machines, and dedicated-host virtual machines can all be provisioned and managed by Oracle Cloud Infrastructure Compute using the same set of APIs. Authentic elastic, self-service, pay-by-the-hour bare-metal servers may be spun up in a matter of minutes, as can flexible Virtual Machines (VMs).

Oracle Cloud is a fully managed, scalable, and highly available solution called Container Engine for Kubernetes that allows users to run containerized programs in the cloud. When the development team needs to build, deploy, and maintain cloud-native applications with the reliability, use Container Engine. The Container Engine provisions the computing resources that the applications need on Oracle Cloud Infrastructure in an existing OCI tenancy based on the specifications provided.

  • Storage

Oracle Cloud Infrastructure Object Storage offers high throughput storage with a practically infinite capacity for unstructured data like logs, photos, and videos. Programs like Spark for extensive persistence can use Object Storage.
