Which PaaS storage architecture should be used if an organization wants to store presentations, documents, and audio files?

Choosing an object storage architecture is the most suitable option for storing presentations, documents, and audio files due to its inherent design features. Object storage is specifically optimized for large amounts of unstructured data, which encompasses the types of files mentioned in the question.

This type of storage organizes data into discrete units called "objects," each containing the data itself, metadata, and a unique identifier. This design allows for easy storage, retrieval, and scalability, making it particularly effective for content like multimedia files and documents. Object storage also typically offers high durability and availability, which is essential for organizations that need reliable access to their content.

Additionally, object storage systems often come with features like automatic replication and distribution across multiple locations, enhancing data protection and accessibility. This aligns perfectly with the needs of organizations that manage large volumes of presentations, documents, and audio files, enabling efficient management and retrieval of such data.

The other options, such as relational databases, block storage, and distributed storage, while useful in certain contexts, do not offer the same level of flexibility and efficiency for handling unstructured data in the way object storage does.
