IaaS, PaaS, SaaS, managed services
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
tell the service models apart by what the customer still operates.
Planned topics
- IaaS: you rent virtual machines, disks, and networks; you run the OS, runtime, patching, and application.
- PaaS: you deploy code or containers; the provider runs the OS and runtime.
- SaaS: you use a finished application; you configure it and manage its users and data.
- Managed service: one component (a database, a queue) run by the provider; you still design, size, secure, and monitor its use.
- The models are a spectrum; the useful question is "what do my people still have to do at 3 a.m.?"
