What is this?
IaaS, PaaS, and SaaS differ by how much you manage vs the provider.
Why should you care?
CloudVerse maps each workload to the right model to control ops cost.
See it live — copy this example
Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.
# Who patches what?
# IaaS: you manage OS+app on VMs
# PaaS: you deploy app; provider manages runtime
# SaaS: you use the app (email, CRM)
# CloudVerse shop: IaaS for custom APIs, PaaS for workers, SaaS for emailWhat happened?
- More managed usually means less control and different pricing.
- Shared responsibility shifts with the model.
Practice next
- Classify email, Kubernetes nodes, and Heroku-style app.
- Pick model for CloudVerse API.
- Note what you still secure.
- Move one lab from IaaS VM to PaaS.
- List one SaaS you already use.
Remember
IaaS/PaaS/SaaS ladder. Ops vs control. Map workloads deliberately.
CloudVerse model map
API on IaaS, email on SaaS.
Outcome: Ops load matches the choice.
