What Happened

  • cloud computing let companies run software, storage, and compute over the internet instead of owning servers

  • AWS (2006) pioneered the shift, followed by Azure, Google Cloud, and specialized platforms

  • on-demand resources replaced large upfront hardware costs

  • startups scaled to global audiences instantly; enterprises modernized IT

  • cloud became the backbone for mobile apps, streaming, e-commerce, AI, and SaaS

  • today, cloud infrastructure underpins most of the digital economy

What Drove the Transformation

  • shared infrastructure made computing cheaper and usage-based

  • elasticity allowed apps to scale from a few users to millions without new hardware

  • global data centers enabled instant worldwide distribution

  • APIs and turnkey services (databases, storage, auth, analytics) boosted developer productivity

  • SaaS and subscription models emerged, replacing installed software

  • smartphones + cloud backends powered social media, ride-sharing, messaging, and streaming

  • enterprises migrated to reduce cost, increase agility, and retire legacy systems

  • hybrid and multi-cloud architectures improved resilience and flexibility

The Economic Lessons

  • moving from fixed costs to variable costs unlocks innovation and experimentation

  • infrastructure shifts create the biggest technology booms by lowering barriers to building

  • cloud-native companies gain speed, global reach, and operational leverage

  • platform lock-in creates durable moats for AWS, Azure, and GCP

  • foundational infrastructure (compute, storage, networking, data) drives downstream industries like AI, SaaS, and digital media

  • cloud is now the economic base layer of the modern internet, and those who master it gain long-term scale and defensibility
