IDC의 세계 전용 클라우드 인프라 및 서비스 분류(2026년)

This IDC study provides a detailed taxonomy for the dedicated cloud infrastructure and services market. The document covers the definitions of various building blocks and provides a top-level overview of dedicated cloud segments. IDC is retiring the term private cloud and replacing it with the term dedicated cloud, but the definition remains the same: environments in which IT resources are dedicated to a single organization and managed and delivered to end users utilizing cloud attributes. The growing availability of commercial and open source cloud platforms enables the increasing adoption of dedicated clouds by enterprises, while the proliferation of infrastructure management platforms for managing resources across multiple environments drives the expanding growth of hybrid IT environments."Dedicated cloud infrastructure as a service has become the defining ground for the enterprises seeking operational control over data placement, compliance posture, or workload governance," said Jasdeep Singh, research manager for IDC's Cloud and Infrastructure Services. "As OEM vendors, cloud service providers, and managed service providers compete in this market, the conversation has shifted from who can build the cloud to who can govern it, on the customer's terms, at the customer's choice of location, and in compliance with their regulatory and AI risk realities."
