Introduction to Cloud Services 1.1 Definition and Evolution Cloud services, defined as on-demand computing resources delivered via the internet, have transformed modern IT infrastructure. The term originates from the metaphor of storing data "in the cloud" as opposed to physical servers. Since the commercialization of Salesforce's cloud CRM in 1999, this model has evolved through three distinct phases:

• Early 2000s: Infrastructure-as-a-Service (IaaS) pioneers like Amazon Web Services (AWS) disrupting traditional hosting
• 2010s: Platform-as-a-Service (PaaS) expansion with Microsoft Azure and Google Cloud Platform
• 2020s: Multi-cloud and hybrid cloud normalization post-pandemic

2 Global Market Overview According to Gartner's 2023 report, the cloud services market reached $514 billion with 18.4% CAGR. Key regional dynamics include:

• North America: 43% market share (US-centric)
• Asia-Pacific: 28% growth driven by digital transformation
• Europe: Strict GDPR compliance requirements
• Latin America: 22% CAGR from financial sector adoption
