Hybrid Cloud and Hyperconverged Infrastructure Framework for Digital Transformation in Saudi Organisations
Abstract
Saudi organisations are modernising under strong national expectations for digital government, data value creation, service resilience, and cybersecurity. Yet public cloud adoption alone cannot resolve the combined requirements of legacy integration, workload sovereignty, predictable performance, operational continuity, and rapid innovation. This review develops an evidence-based framework in which hyperconverged infrastructure (HCI) forms a software-defined private-cloud foundation and hybrid cloud provides selective access to elastic public services. A structured integrative review synthesised 30 academic, regulatory, standards, and policy sources published from 2020 to 2025. Evidence was coded against technological, organisational, environmental, governance, security, and value-realisation dimensions. The synthesis finds that the strongest architecture is neither cloud-first in a literal placement sense nor an indiscriminate retention of on-premises systems. It is a policy-led operating model that classifies workloads, separates control and execution concerns, standardises identity and observability, and assigns each application to an HCI, sovereign-cloud, public-cloud, or edge location according to evidence. HCI contributes consolidation, locality, repeatable operations, and recovery, while public cloud contributes elasticity, managed innovation services, and geographic reach. Their combination succeeds only when platform engineering, FinOps, zero-trust security, data governance, vendor-exit planning, and skills development are designed as one transformation system. The proposed framework links national obligations to architecture decisions and measurable outcomes. It offers Saudi ministries, regulated enterprises, universities, healthcare providers, and large private organisations a staged route from fragmented infrastructure to a governed hybrid platform. The review also identifies research needs concerning longitudinal value, energy performance, Arabic-language operations, sovereign-cloud interoperability, and sector-specific empirical validation.
