IDC의 세계 디지털 주권 분류(2026년)

This IDC study presents a comprehensive reframing of the digital sovereignty (DxSo) landscape, reflecting the evolving priorities and complexities of the market. The taxonomy, first introduced in 2023 and revised in 2024 to emphasize cloud sovereignty, now aligns with a broader DxSo concept, expanding from the original three pillars of data, technical, and operational sovereignty to four primary technology markets: business apps, business platforms, IT infrastructure, and IT operations and assurance.This updated taxonomy provides a detailed hierarchical mapping of primary and secondary markets, offering clarity on how organizations can assemble technologies, operational models, and strategies to achieve coherent and consistent digital sovereignty. It offers a robust, forward-looking framework that captures the dynamic nature of digital sovereignty, enabling stakeholders to navigate regulatory, operational, and technological challenges with greater clarity and strategic intent.The taxonomy supports IDC's research and deliverables, including market forecasts, vendor profiles, and customer buying patterns, and is foundational for related services such as the Digital Sovereignty CIS and the forthcoming Sovereign AI Infrastructure Index SIS.IDC defines digital sovereignty as the capacity for digital self-determination by nations, organizations, and individuals, emphasizing total control over data management, storage, and processing. The taxonomy's segmentation covers a wide range of technology markets, including new and reclassified secondary markets under each primary category. Business apps and business platforms now encompass a broader set of software and development tools, while IT infrastructure and IT operations and assurance consolidate previously fragmented markets, reflecting the convergence of compute, storage, networking, and management functions.The taxonomy also introduces a refined digital sovereignty strategy stack, which articulates the layered approach organizations must take - from applications, platforms, and infrastructure to various assurance levels (IT, business, governance, and customer) - to ensure resilience, compliance, and operational sovereignty. Cloud remains central to digital sovereignty, with IDC positioning sovereign cloud as a subset of DxSo, subject to all relevant data laws and regulations, and applicable to both public and private cloud deployments.IDC's methodology ensures the taxonomy remains aligned with other IDC frameworks and addresses critical questions around stack completeness, data residency, and market measurement. The taxonomy is designed to track global DxSo spending and its economic impact, providing actionable insights for IT buyers, vendors, and service providers."Digital sovereignty has switched gears over the years. It has evolved from digital self-determination and digital self-sufficiency to survivability at the national level, given the crucial nature of digital technologies underpinning society and critical national infrastructure. As a result, this taxonomy has also evolved and now encompasses the IT products, platforms, and services that are needed to assure sovereignty at a much broader scale, going further than just data sovereignty and cloud sovereignty, and even the relatively newer concept of AI sovereignty," said Rahiel Nasir, research director, Cloud and Infrastructure Services, IDC.
