Abstract: The evolving demands of enterprise IT are driving organizations to modernize legacy infrastructures while leveraging the flexibility and scalability of hybrid cloud platforms. Oracle Enterprise Linux (OEL), traditionally a reliable foundation for enterprise workloads, faces challenges in cost, cloud readiness, and integration with modern open-source tools. This review explores the strategic migration from OEL to Red Hat Enterprise Linux (RHEL), emphasizing hybrid cloud deployment as a pathway to operational efficiency, scalability, and future-ready IT environments. The article examines comparative aspects of OEL and RHEL, including architecture, system features, package management, and enterprise support considerations. A structured migration framework is presented, encompassing workload assessment, risk analysis, phased adoption, and containerization strategies to ensure minimal disruption and consistent performance. Hybrid cloud architectures leveraging RHEL enable enterprises to retain critical workloads on-premises while utilizing cloud resources for elasticity, analytics, and AI-driven insights. Containerization and microservices architectures, orchestrated via Kubernetes and Red Hat OpenShift, facilitate portability, modularity, and high availability across heterogeneous infrastructures. Automation and DevOps practices, including Infrastructure as Code (IaC), CI/CD pipelines, and predictive monitoring, streamline deployments, enhance operational consistency, and reduce human error. Security and compliance frameworks, encompassing identity and access management, encryption, auditing, and adherence to regulatory standards, safeguard critical data throughout the hybrid environment. Case studies from financial and telecommunications sectors illustrate practical insights, benefits, and lessons learned during real-world migrations. Emerging trends, including AI-driven analytics, serverless computing, and edge processing, are analyzed for their impact on hybrid cloud operations. By synthesizing technical guidance, strategic recommendations, and industry best practices, this review provides a comprehensive roadmap for enterprises transitioning from OEL to RHEL-powered hybrid cloud infrastructures, enabling agility, resilience, and sustainable competitive advantage in modern IT landscapes.
