What it shows

  • IaaS provides raw compute and storage; you manage OS, runtimes, and apps.
  • PaaS manages OS and runtimes so engineers focus only on application code.
  • SaaS delivers finished software where vendors manage the entire stack.

The takeaway

Higher cloud abstractions trade operational control for faster feature delivery and lower maintenance burden.
