The Oracle Linux operating system is engineered for open cloud infrastructure. It delivers leading performance, scalability, reliability and security for enterprise SaaS and PaaS workloads as well as traditional enterprise applications. Oracle Linux Support offers access to award-winning Oracle support resources and Linux support specialists, zero-downtime updates using Ksplice, additional management tools such as Oracle Enterprise Manager and lifetime support, all at a low cost. Unlike many other commercial Linux distributions, Oracle Linux is easy to download and completely free to use, distribute and update.

Running Oracle Linux with UEK gives you additional advanced features and security enhancements. Some of which are:
• Docker – Safely and securely run multiple applications on a single host, without the risk of interference with each other. Docker containers are lightweight and resource friendly, which saves on rack space and power.
• DTrace – DTrace is a comprehensive dynamic tracing framework that provides a powerful infrastructure to permit administrators, developers and service personnel to concisely answer arbitrary questions about the behavior of the operating system and user programs in real time.
• Oracle Cluster File System 2 (OCFS2) – OCFS2 is a general purpose, extent-based clustered file system that Oracle developed and contributed to the Linux community. It provides an open source, enterprise-class alternative to proprietary cluster file systems, and provides both high performance and high availability.
• Oracle Workload Optimizations – Some of the many optimizations available are:
• Enhanced memory performance, by attempting to better locate a process near its memory and better placement of workloads that do not fit on one NUMA node.
• Up to 3.6x performance improvement of SPECjbb through optimizations that help eliminate lock contention.
• Simple to use SSDs as a block cache for slower block devices with bcache. Supports many millions of IOps on NVM-Express and high-end PCI-E devices with a new, scaled multiqueue block layer subsystem.
