What is Oracle Cloud Infrastructure (OCI)?

OCI is Oracle's public cloud platform providing compute, storage, networking, and database services, with particularly deep integration for running Oracle Database and enterprise applications.

How does Oracle Cloud compare to AWS and Azure?

OCI offers a similar core set of infrastructure services to [AWS](/glossary/aws) and [Azure](/glossary/azure) but is smaller in overall market share and managed-service breadth, differentiating instead on Oracle Database performance, flat pricing, and enterprise application integration.

Is there a free tier for Oracle Cloud?

Yes. Oracle offers an 'Always Free' tier that includes limited compute instances, Autonomous Database instances, and storage that do not expire after a trial period.

What is Oracle Autonomous Database?

It is a managed database service that automates patching, tuning, backups, and security, reducing the operational overhead of running Oracle Database in production.

Can Oracle Database run on Azure or Google Cloud?

Yes. Oracle has built multicloud interconnects that let customers run Oracle Database services physically inside Azure and Google Cloud data centers while managing compute in those platforms.

Who typically uses Oracle Cloud?

Large enterprises with existing investments in Oracle Database, Oracle ERP/Fusion applications, or workloads that benefit from Oracle's high-performance database and networking infrastructure.

Overview

Oracle Cloud Infrastructure is Oracle's answer to the hyperscale cloud market dominated by AWS, Azure, and Google Cloud. It provides the standard building blocks of modern cloud computing — virtual machines, bare-metal servers, block and object storage, virtual networking, and Kubernetes-based container orchestration — alongside deep integration with Oracle Database, Oracle Fusion applications, and Oracle's Autonomous Database, a self-patching, self-tuning managed database service. OCI is architected around isolated network regions and availability domains for fault tolerance, with a distinctive flat, predictable pricing model and a RDMA-based cluster network aimed at high-performance computing and AI training workloads. It has positioned itself heavily around enterprise migration of existing Oracle software estates, multicloud partnerships that let customers run Oracle Database services inside Azure and Google Cloud data centers, and an "Always Free" tier for small compute and database instances. For organizations already running Oracle databases or enterprise applications, OCI is often the natural landing zone for a broader cloud migration, competing on cost and database performance rather than breadth of managed services compared to the larger hyperscalers.

Key Features

Autonomous Database with self-patching, self-tuning, and self-securing capabilities
Bare-metal and virtual machine compute instances with predictable, flat pricing
RDMA cluster networking aimed at HPC and AI/ML training workloads
Multicloud interconnects letting Oracle Database run natively inside Azure and Google Cloud
Object, block, and file storage tiers with lifecycle management
Oracle Kubernetes Engine (OKE) for managed container orchestration
Always Free tier covering small compute, storage, and database instances
Tight integration with Oracle Fusion applications and enterprise resource planning software

Use Cases
