Is CaaS a certain type of PaaS?

I've recently asked myself if Container as a Service was a certain type of Platform as a Service or not. Is a Container a Platform ?

Solution

  • PaaS and CaaS are two different things.

    On a PaaS, you only run your code in a cartridge (which can be a VM or even a container) but you'll only be able to run code that is supported by your PaaS provider. You won't be able to modify the OS on which your code is running. Example: Heroku

    On a CaaS, you will be able to run a container and you won't be limited by the languages supported by your PaaS provider. You can run anything you want in your container as long as the container engine is supported by your CaaS provider. Example: Amazon Container Services (ECS)

    CaaS falls somewhere between Infrastructure as a Service (IaaS) and Platform as a Service (PaaS).
