The answer is Platform as a Service (PaaS). It is the cloud service that binds application code to libraries that provide access to the infrastructure an application needs.

Quick scoop

PaaS gives developers a managed platform to build, run, and deploy apps without handling the underlying servers and infrastructure directly.

That is why it fits this description better than IaaS, SaaS, hybrid cloud, or virtualized data centers.

If you want, I can also give you a one-line comparison of PaaS vs IaaS vs SaaS.
