Oracle Cloud Infrastructure

Oracle Cloud Infrastructure. It is a comprehensive Infrastructure as a service and Platform as a service offering from Oracle Corporation, designed for enterprise workloads. The platform provides high-performance computing, storage, and networking resources in a globally distributed set of data centers. It directly competes with other major public clouds like Amazon Web Services, Microsoft Azure, and Google Cloud Platform.

Overview

The platform is built to run demanding enterprise applications, offering core Compute instances, Block storage, and Object storage with a focus on predictable performance. It supports a broad portfolio of services including Databases, Artificial intelligence, and Container orchestration tools. A key differentiator is its deep integration with Oracle's own software portfolio, such as the Oracle Database and Oracle Fusion Applications. The infrastructure is organized into globally distributed regions and availability zones to ensure resilience and low-latency access for customers worldwide.

Services

Core compute offerings include bare metal and Virtual machine instances, alongside specialized options like GPU accelerators for High-performance computing. Storage services encompass the Oracle Cloud Infrastructure Object Storage service, File storage systems, and a high-performance Block volume service. The platform provides extensive Database as a service options, notably the Autonomous Database, as well as managed services for MySQL, NoSQL databases, and Exadata. Additional services cover Networking, Load balancing (computing), content delivery, Serverless computing, and Internet of things platforms, creating a full-stack cloud environment.

Architecture

Its architecture is based on a non-overlay network design, where each tenant receives true Layer 2 network isolation within a Virtual cloud network. This design minimizes virtualization overhead and provides consistent, low-latency performance comparable to on-premises infrastructure. The physical infrastructure is built using custom hardware, including high-performance SSDs and RDMA-capable networking, often utilizing Mellanox Technologies technology. Regions are composed of multiple, fault-isolated availability zones, all interconnected by a high-bandwidth, low-latency Backbone network.

Security and compliance

Security is foundational, with principles of Defense in depth (computing) and a Zero trust security model integrated into all services. All customer data is encrypted by default, both at rest and in transit, with keys managed through the Oracle Cloud Infrastructure Vault service. The platform maintains a wide array of compliance certifications, including FedRAMP, HIPAA, PCI DSS, and ISO/IEC 27001. It also offers dedicated regions for specific governmental needs, such as the ORACLE CLOUD FOR U.S. DEFENSE and the ORACLE CLOUD FOR U.S. INTELLIGENCE COMMUNITY.

Pricing and availability

It employs a consumption-based pricing model, with costs for compute, storage, and data egress. Unique pricing options include universal credits for sustained use and a cost-effective Compute virtual machine shape. The platform is available in numerous commercial regions worldwide, including locations in North America, Europe, Asia, and South America. Specialized government and national security regions, like those in London and Ashburn, Virginia, cater to sovereign and regulated industry requirements.

History and development

The development began in earnest around 2016, led by executive Thomas Kurian, with the goal of building a second-generation cloud from the ground up. A significant milestone was the 2019 launch of the Oracle Cloud Free Tier, offering always-free resources to attract developers. Major expansions have included the 2020 introduction of the Oracle Cloud VMware Solution and a strategic partnership with Microsoft to enable direct Interconnect between their respective clouds. Continued investment is evident in the rapid global region expansion and the integration of advanced services like the Oracle Cloud Infrastructure Generative AI service.
