Is Horizon provides Iaas or paas

I want to know what kind of service does horizon provides. Does it provides an infrastructure and a person has to create a platform on it. Or Does it provides Platforms and the customers can directly start using it.
If you don’t know what is Iaas and Paas or want to know the difference Iaas Vs Paas ( then you can Cloudways blog as it will be the easier and a more comprehensive resource to learn about.

If you mean sidechains, it will be more like PaaS.
There will be a platform ready to be used upon which people will be able to deploy their solutions.
