PaaS Storage Types

C.

PaaS (Platform-as-a-Service) is a cloud computing service model that provides a platform to develop, run, and manage applications without the need for infrastructure management.

When it comes to storage in PaaS, there are mainly two types of storage, namely structured and unstructured.

Structured storage is a type of storage that follows a specific schema, and its data is organized in a tabular form. This type of storage is used to store relational data, such as data in a database. The structured storage is typically provided in the form of a database management system (DBMS) by the PaaS provider.

Unstructured storage, on the other hand, is a type of storage that does not follow a specific schema, and its data is not organized in a tabular form. This type of storage is used to store non-relational data, such as media files, documents, and other binary data. Unstructured storage is usually provided in the form of an object storage system by the PaaS provider.

Therefore, the correct answer to the question is option C, "Structured and unstructured." Option A is incorrect because freeform is not a standard storage type in PaaS. Option B is incorrect because volume storage is not a standard storage type in PaaS, and object storage falls under the category of unstructured storage. Option D is incorrect because both database and file system storage are types of structured storage, and the question asks for the storage types associated with PaaS.
