Overview
Cloud computing is the backbone of the digital economy. AWS, Azure, and Google Cloud control 65%+ of the $500B+ global cloud infrastructure market, growing 15-20% annually. SaaS companies built on cloud infrastructure are seeing durable demand from enterprise digital transformation, while multi-cloud strategies and AI workload migration drive continued hyperscaler capex investment. The shift from on-premise to cloud is still only 25% complete globally.
Why It Matters: Cloud is not a trend — it is the foundation of all modern software. Every enterprise is migrating to cloud, and AI workloads are accelerating this migration. The hyperscalers operate the most profitable infrastructure businesses in history, while SaaS companies built on cloud rails compound revenue at rates impossible in legacy software.

Key Risks
| Risk Factor | Detail |
|---|---|
| Hyperscaler capex cycle risk | Massive AI capex spending may not generate expected returns, triggering cutbacks |
| Multi-cloud fragmentation | Enterprise demand for vendor neutrality reduces hyperscaler lock-in advantages |
| Margin pressure in SaaS | AI code generation tools reduce software development costs and enterprise licensing value |
| Regulatory scrutiny | Antitrust investigations into cloud market concentration in US and EU |
| Data sovereignty requirements | Government data localization rules fragment global cloud deployments |
