Abstract: Hybrid infrastructures have become the backbone of modern enterprise IT, enabling organizations to achieve agility, scalability, and resilience while meeting performance and compliance requirements. Among the foundational elements of these infrastructures are enterprise-grade Linux distributions, with Oracle Enterprise Linux (OEL) and Red Hat Enterprise Linux (RHEL) standing out as two dominant platforms. This review provides a comprehensive analysis of how OEL and RHEL optimize hybrid infrastructures by balancing database-intensive workloads, containerized applications, and cloud-native services. The discussion highlights their performance optimization techniques, including kernel tuning, NUMA-aware scheduling, and workload consolidation. It further examines advanced security mechanisms such as SELinux, Ksplice, and compliance automation frameworks that ensure regulatory adherence in sensitive industries like healthcare and finance. Emphasis is placed on the role of orchestration technologies such as Kubernetes and OpenShift, which streamline interoperability across multi-cloud and hybrid models. Through detailed case studies in financial services, healthcare, and retail, the article illustrates practical implementations that leverage the complementary strengths of OEL and RHEL. The findings underscore that adopting a dual-Linux strategy empowers enterprises to optimize workload placement, reduce downtime, and future-proof IT operations, making OEL and RHEL a critical foundation for digital transformation.
