What type of storage does Liferay utilize for content management?

Liferay utilizes a combination of a database and file storage for content management, which allows it to efficiently manage and serve a wide variety of content types. The database is primarily used for structured data, such as user information and metadata related to the content, while file storage is used for the actual content files, ensuring that large files can be handled without imposing undue load on the database.

By using both storage solutions, Liferay achieves a balance between performance and scalability. The database can handle transactional operations and quick retrieval of content metadata, while file storage is optimized for storing larger files and ensuring high availability. This dual approach effectively provides flexibility and enables easy management of assets across different types of content, making it robust for enterprise-level applications where content management needs can vary significantly.

Other methods, such as relying solely on in-memory storage, cloud storage exclusively, or external hard drives, do not provide the same versatility and reliability that the combination of database and file storage offers, thus underscoring why this choice is the most fitting for Liferay's content management system.
