2026年国内クラウド市場ベンダーのビジネス動向分析

Satoshi Matsumoto — Fri, 20 Feb 2026 05:00:00 GMT

本調査レポートは、2026年1月末までに収集した情報を基に、国内クラウド市場におけるクラウドインフラストラクチャ／プラットフォーム領域の主要ベンダーのビジネス動向をまとめたものである。また、国内クラウド市場に大きな影響を与えるAI（Artificial Intelligence）、ITモダナイゼーションなどの動向を考察し、ベンダーが成長するための提言を行っている。

2025年の国内クラウド市場では、多くのベンダーが注力領域としてAIとITモダナイゼーションを挙げている。この動向は2023年頃から大きく変わらないが、先駆的な取り組みから、より実践的な内容へと変化している。他方、多くのベンダーが同じ分野を注力領域としているため、差別化要素の提示が困難となっている。「国内クラウド市場では、イノベーションが注目される領域と、機能強化といった実践的なオファリングが併存して訴求されている。ベンダーは、ユーザー企業の投資対ビジネス価値に焦点を合わせ、自らの投資領域とエコシステムとしての提供価値を提示することが、ベンダーの差別化戦略としても有効となるであろう」と、IDC Japan、Software, Services and IT Spendingのリサーチディレクターである松本聡は述べている。

IDC's Worldwide Public Cloud Infrastructure as a Service Taxonomy, 2026

Jasdeep Singh, Taranvir Singh, Dave McCarthy, Manish Ranjan, Ashish Nadkarni — Thu, 19 Feb 2026 05:00:00 GMT

This IDC study provides a detailed taxonomy of the public cloud infrastructure-as-a-service (IaaS) market. The scope of this document includes public cloud compute, storage, and networking services.

"As organizations advance their AI journeys, public cloud IaaS is becoming increasingly foundational," said Jasdeep Singh, research manager, Cloud and Infrastructure Services at IDC. "Cloud providers are evolving compute, storage, and networking services to support performance-intensive workloads. These newer IaaS services also reflect growing enterprise demand for hybrid and multicloud support as workloads become more distributed."

IDC´s Worldwide Managed Cloud Services Taxonomy, 2026

Thu, 19 Feb 2026 05:00:00 GMT

This IDC study provides a detailed view of IDC's taxonomy for the competitive services market called managed cloud services (MCS) that incorporates IDC's four technology outsourcing services foundation markets and its relationship to the overall portfolio of different types of cloud engagements. This taxonomy highlights how MCS is segmented into three primary markets of managed private cloud, managed public cloud, and managed hybrid cloud services and further refines these primary managed cloud services into a set of secondary markets within MCS. Finally, this taxonomy also provides a detailed framework of the role and structure of multicloud management as part of managed cloud services and how MCS is part of an evolution of technology operations that is replacing traditional (noncloud) technologies and architectures.

"IDC's worldwide managed cloud services taxonomy provides a comprehensive framework of a disruptive consumption and delivery model used to support different outsourcing-managed services markets," said David Tapper, program VP, Outsourcing and Managed Cloud Services. "Ultimately, managed cloud services, along with other digital capabilities, are becoming the de facto means of supporting customer needs for managed services."

AT&T, AWS, and Amazon Leo Deepen Strategic Collaboration Across Cloud, Fiber, and Satellite Domains

Peter Chahal, Ahmad Latif Ali, Simon Baker — Wed, 18 Feb 2026 05:00:00 GMT

AT&T's expanded collaboration with AWS and Amazon Leo marks an important milestone in the telecommunications industry's shift toward hybrid, cloud‑centric operational models. The scale of AT&T's planned migration, moving broad IT estates onto AWS Regions and Outposts, signals growing confidence in cloud‑managed infrastructure for mission‑critical telco workloads and reflects an AI‑driven approach to migration. By combining its high‑capacity fiber with AWS cloud and AI capabilities and integrating Amazon Leo satellite connectivity, AT&T is building a more adaptable and resilient network architecture that can serve a wider geographic footprint. IDC views this partnership not only as a validation of AWS' hybrid cloud strategy but also as a reference model for telecom operators modernizing legacy systems while maintaining necessary on‑premises control.
