Cloud computing is the on-demand delivery of IT resources over the internet, allowing companies to swap massive upfront hardware costs for a flexible, pay-as-you-go model. By leveraging massive economies of scale, providers like AWS, Azure, and Google manage the underlying hardware, enabling businesses to scale instantly and focus on innovation. Today, this technology serves as the backbone for the global internet, the startup economy, and the massive infrastructure required to train modern artificial intelligence models.
Cloud computing delivers scalable computing infrastructure—including compute power, object and block storage, managed databases, global networking, and AI acceleration—over the internet under a utility pay-as-you-go economic model.
The global cloud infrastructure services market exceeds $270 billion annually, expanding at 18–22% year-over-year. Market share is concentrated among three US hyperscalers:
| Cloud Provider | Parent Company | Estimated Market Share | Annualized Revenue Run-Rate | Operating Margin (Est.) | |---|---|---|---|---| | AWS (Amazon Web Services) | Amazon.com | 31% | ~$100 Billion | 30% - 38% | | Microsoft Azure | Microsoft | 25% | ~$75 Billion (Infra) | 40%+ (Commercial Cloud) | | GCP (Google Cloud Platform) | Alphabet | 11% | ~$38 Billion | 8% - 11% | | Alibaba Cloud / Others | Alibaba / Various | 33% Combined | N/A | Variable |
Cloud architecture is organized into three delivery tiers:
Provides virtualized or bare-metal compute instances (AWS EC2, Azure VMs), block storage (AWS EBS), object storage (AWS S3), and virtual private clouds (VPCs). Customers manage operating systems, applications, and middleware, while hyperscalers manage physical hardware and data centers.
Provides managed execution environments, database engines (AWS Aurora, Google Cloud Spanner), and container orchestration (Amazon EKS, Azure AKS, Google GKE). Developers deploy application code without managing underlying server OS patching or infrastructure provisioning.
Delivers complete business applications over the web (Microsoft 365, Salesforce, ServiceNow, Workday), billed per user seat per month.
Cloud migration shifts corporate IT budgets from upfront Capital Expenditures (CapEx) to variable Operational Expenditures (OpEx). However, unoptimized cloud usage frequently leads to budget overruns, giving rise to Cloud Financial Operations (FinOps).
Hyperscalers charge zero fees for inbound data transfers but levy substantial fees on outbound data egress ($0.08 to $0.12 per gigabyte). Egress fees create economic friction against multi-cloud strategies or migrating workloads back to on-premises servers.

The explosion of Large Language Models (LLMs) shifted cloud CapEx toward AI compute clusters. Modern AI workloads require high-density GPU nodes connected via high-bandwidth networking:
