Which cloud models are characterized by their use of structured versus unstructured storage types?

The correct answer highlights the characteristics of Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) in relation to structured and unstructured storage types.

IaaS provides users with virtualized computing resources over the internet. This model can accommodate various types of storage, including structured storage, which is well-organized and manageable, such as databases. On the other hand, IaaS also supports unstructured data storage, such as files and blobs, through the storage services it offers. This flexibility allows organizations to choose the appropriate storage type based on their needs.

PaaS, meanwhile, offers a platform for developers to build, deploy, and manage applications without handling the infrastructure. It typically includes managed database services that support structured data, but it can also support unstructured storage as part of the application's functionality. The support for both structured and unstructured storage types makes IaaS and PaaS complementary in cloud environments, allowing businesses to utilize a wide range of data formats.

The other options lack the same clear connection to structured and unstructured storage types. SaaS primarily delivers software applications over the internet, focusing more on service delivery than on storage specifics. FaaS, while related to serverless computing,
