Core Services of Oracle OCI

Compute Services

OCI offers a variety of compute options to suit different workloads.

Virtual Machines

Oracle provides flexible virtual machine (VM) instances that can be customized for various performance needs. These VMs are ideal for running general-purpose applications, web servers, and small databases.

Bare Metal Servers

OCI offers bare metal servers for applications requiring high performance and low latency. These provide direct access to the hardware, bypassing the virtualization layer, which is perfect for intensive workloads like HPC and big data analytics.

Container Services

OCI supports containerized applications through Oracle Kubernetes Engine (OKE). This managed Kubernetes service simplifies the deployment, scaling, and management of containerized applications, ensuring high availability and scalability.

Storage Services

OCI’s storage solutions are designed to handle diverse data storage needs.

Object Storage

Object Storage is a scalable and durable storage service for unstructured data. It is ideal for storing large amounts of data, such as backups, log files and media files.

Block Volumes

Block Volumes provide high-performance block storage for use with OCI compute instances. These volumes are perfect for databases, applications requiring low-latency storage, and other I/O-intensive workloads.

Archive Storage

OCI offers archive storage for long-term data retention and archival. This low-cost storage option is suitable for storing infrequently accessed data.

Networking Services

OCI’s networking services ensure secure and high-performance connectivity.

Virtual Cloud Network (VCN)

A VCN is a customizable private network in OCI that enables secure communication between your cloud resources. It functions like a traditional data center network, providing isolation, security, and control.

Load Balancing

OCI’s Load Balancing service distributes incoming traffic across multiple compute instances, ensuring high availability and reliability. It supports both HTTP and TCP traffic and offers advanced routing and health check features.


FastConnect provides a dedicated, private connection between your on-premises infrastructure and OCI. This service ensures high bandwidth and low latency, making it ideal for hybrid cloud environments.

Database Services

OCI excels in database services, offering several options to meet different requirements.

Oracle Autonomous Database

The Autonomous Database is a self-driving, self-securing, and self-repairing database service that automates routine tasks like patching, tuning, and backups. It is available in two flavors: Autonomous Data Warehouse (ADW) for analytics and data warehousing and Autonomous Transaction Processing (ATP) for transaction processing and mixed workloads.

Oracle Exadata Cloud Service

Exadata Cloud Service provides high-performance database capabilities in the cloud, optimized for running Oracle databases. It combines the power of Exadata with the simplicity and flexibility of OCI.

Oracle NoSQL Database

OCI offers Oracle NoSQL Database for applications requiring flexible, scalable, and low-latency data management. It is ideal for IoT, personalization, and real-time big data applications.

Security and Compliance

Security Features

OCI is built with a security-first approach, offering comprehensive security features to protect your data and applications.

  • Identity and Access Management (IAM): Centralized access control and user management.
  • Data Encryption: All data is encrypted at rest and in transit.
  • Network Security: OCI provides advanced network security features like firewalls, security lists, and private subnets.


OCI meets numerous industry standards and regulatory requirements, including ISO, SOC, GDPR, and HIPAA. This makes it suitable for businesses in highly regulated industries.

Cost Management

Pricing Model

OCI offers a straightforward pricing model with pay-as-you-go and monthly flex options. The pay-as-you-go model allows you to pay only for the resources you use, while the monthly flex option provides discounts for committing to a monthly usage level.

Cost Management Tools

OCI provides several tools to help you manage and optimize your costs.

  • Oracle Cloud Cost Management: A comprehensive tool for tracking and controlling cloud spending.
  • Budgets and Alerts: Set budgets and receive alerts when spending approaches or exceeds predefined limits.
  • Cost Analysis: Detailed reports and analytics to understand spending patterns and identify cost-saving opportunities.

Integration and Ecosystem

Integration with Oracle Products

OCI is designed to integrate seamlessly with other Oracle products and services, including Oracle SaaS applications, on-premises Oracle databases, and third-party applications. This makes it an excellent choice for organizations already using Oracle technologies.

Third-Party Integrations

OCI supports a wide range of third-party integrations through APIs and SDKs, allowing you to connect with other cloud services, DevOps tools, and enterprise applications.

Use Cases

Enterprise Applications

OCI is ideal for running enterprise applications like Oracle E-Business Suite, PeopleSoft, and JD Edwards. Its high performance, scalability, and security features ensure these applications run smoothly and efficiently.

High-Performance Computing (HPC)

For workloads requiring significant computational power, such as scientific simulations, financial modeling, and big data analytics, OCI’s bare metal servers and high-performance networking provide the necessary resources.

Cloud-Native Applications

OCI supports modern, cloud-native applications through services like Oracle Kubernetes Engine (OKE), Oracle Functions, and API Gateway. These services enable developers to build, deploy, and manage applications using microservices architectures.

Hybrid Cloud

OCI’s networking services, like FastConnect, allow seamless integration between on-premises infrastructure and cloud resources, making it an excellent choice for hybrid cloud environments.
