What Is Oracle Cloud?
Oracle Cloud is a comprehensive enterprise cloud platform developed by Oracle Corporation. It offers a broad suite of Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) offerings. Unlike general-purpose public clouds, Oracle Cloud Infrastructure (OCI) was built from the ground up to support the most demanding databases and mission-critical applications. It focuses heavily on high-performance computing (HPC), automation, and data security, making it a preferred choice for global enterprises across regulated and data‑intensive industries that cannot afford downtime or latency issues.
