What is Oracle Cloud? Types of Services

Oracle Cloud is a cloud computing platform developed by Oracle Corporation that allows users to access a variety of computing, storage, and application services without investing in on-premises hardware infrastructure.

Oracle Cloud Infrastructure (OCI) — IaaS Service

OCI is the highlight of Oracle Cloud with its Infrastructure as a Service (IaaS) model. OCI enables the deployment and management of applications on the cloud platform, helping reduce costs. Enterprises can choose between Virtual Machines (VM) and Bare Metal servers.

Oracle Cloud Platform — PaaS Service

Oracle Cloud Platform allows developers to build and deploy applications quickly without worrying about infrastructure. The platform provides data integration tools, intelligent analytics, and many developer support services.

Oracle Cloud Application — SaaS Service

Cloud-based applications serve diverse business needs: Human Capital Management (HCM), Customer Relationship Management (CRM), and Enterprise Resource Planning (ERP).

Oracle Cloud Infrastructure (OCI) Services

Oracle Cloud Infrastructure is not just an IaaS service but also a powerful platform for enterprises looking to leverage cloud technology.

Features

  • Flexible Computing: Choose between virtual machines and Bare Metal, optimizing cost and performance.
  • Diverse Storage: Object Storage, Block Storage, and Archive Storage.
  • Reliable Networking: Seamless connectivity between applications and services.

Advantages

  • Cost Efficiency: Flexible pricing — pay only for resources actually used.
  • Scalability: Easily adapts to changing demands.
