Global Cloud Computing Market: Trends, Policies, and Data Privacy Challenges

Highlights

90% of U.S. startups choose public cloud services as their primary IT platform.

In 2014, only nine European companies ranked among the world’s top 100 cloud providers, and none from Japan.

The U.S. requires "FedRAMP" certification for government‑grade cloud services, with additional controls for "fly‑in‑the‑lake" (fly‑in‑the‑lake) deployments.

Personal data protection in cross‑border data transfers has become a major obstacle to international data flows.

Introduction

Global cloud computing services have maintained high growth rates in recent years. Gartner reports that the market reached $152.8 billion in 2014, growing at 17.9%, with IaaS, PaaS, and SaaS accounting for $42.5 billion of that total. Cloud services are expanding four times faster than overall IT spending and are expected to increase their share of global IT expenditure from 3.6% in 2013 to 6.6% in 2018.

Governments worldwide are formulating national strategies and action plans, using procurement standards, service specifications, and management regulations as references for broader industry adoption.

Cloud Computing Market Characteristics

Analyzing each country’s industrial policies and legal frameworks requires understanding their cloud ecosystems.

1. United States

The massive U.S. internet industry drives strong market demand, and cloud adoption is expanding into vertical sectors.

90% of U.S. startups prefer public cloud services for IT system construction.

The Federal Cloud Computing Strategy has made the government a major cloud consumer, with over 300 agencies using public cloud services.

The CIA plans to spend $600 million over the next decade on Amazon Web Services.

From the supply side, the U.S. cloud industry is mature, with leading vendors continuously strengthening their positions and expanding globally.

U.S. companies dominate the global top‑100 list, holding 84 slots. Market share highlights include:

Amazon controls 40% of the global IaaS market.

Microsoft holds 64% of the global PaaS market.

Salesforce accounts for 21% of the global SaaS market.

These giants also operate data centers worldwide and continue to expand.

2. Europe and Japan

Both regions have large, growing demand but lack strong domestic cloud vendors.

UK’s 2013 Government Cloud Strategy aims for 50% of new IT spend to be on public cloud services by 2015.

Germany’s Cloud Computing Action Plan encourages federal and state agencies to adopt cloud technologies.

Japan’s Ministry of Internal Affairs and Communications promotes a “Smart Cloud” strategy for government use.

However, Europe and Japan have few home‑grown cloud providers; in 2014 only nine European firms and no Japanese firms appeared in the global top‑100.

U.S. providers such as Amazon, Microsoft, and Google have established data centers in these regions, offering localized services.

National Industry Policies

1. United States – Strong Industry, Light Regulation

The U.S. treats cloud services like any other internet service, without a dedicated regulatory framework. Specific high‑impact use cases, such as government cloud adoption, require FedRAMP certification, which defines low, moderate, and high impact baselines.

Government, community, public, and private cloud services must meet the moderate impact baseline.

Fly‑in‑the‑lake cloud deployments must meet the high impact baseline and provide additional security controls for confidential data.

2. European Union – Weak Industry, Strong Regulation

The EU adopts a stricter regulatory approach to foster a domestic cloud industry. In June 2013 the EU Parliament adopted the Critical Information Infrastructure Protection (CIIP) resolution, bringing cloud services under heightened oversight.

UK public sector procurement uses the G‑Cloud online marketplace (CloudStore). Cloud providers must satisfy the G‑Cloud contract framework and obtain G‑Cloud certification, which aligns with ISO 27001 and UK government information standards.

Certified service categories include IaaS, PaaS, SaaS, and Specialist Cloud Services (SCS).

The UK prohibits storing government data abroad and imposes strict network connection requirements, effectively blocking foreign cloud providers that cannot meet these standards.

3. South Korea – Emphasis on Regulation

South Korea’s Cloud Computing Development and User Protection Act treats cloud services as value‑added services subject to government certification by the Korea Cloud Service Association (KCSA). Providers must submit detailed reports to the government as a condition for operating in Korea.

Global Cloud Computing Legal Landscape

Data privacy and cross‑border data flows have become central concerns worldwide.

Cloud service models raise issues of user privacy, data misuse, and regulatory compliance.

Massive data aggregation and transnational movement create challenges regarding applicable law, data leakage, and control.

Post‑Snowden, the dominant role of the United States in cloud computing has prompted many nations to strengthen oversight of cross‑border data transfers.

Inconsistent data‑protection legislation across countries makes personal data protection a major barrier to international data flows.

International bodies and major economies are working to harmonize rules and reduce obstacles to global data movement.

EU standards assess third‑country data‑protection adequacy; transfers to non‑adequate jurisdictions are generally prohibited.

The U.S.–EU Safe Harbor (and later U.S.–Switzerland frameworks) provided certification mechanisms for compliant data handling.

Taiwan’s regulations restrict cross‑border transfers of personal data by non‑government entities lacking adequate protection.

South Korea’s Personal Information Protection Act mandates policies to safeguard cross‑border personal data transfers.
