• Scale-out NAS: Scale-out NAS architecture allows the addition of nodes to the NAS cluster seamlessly. Each node contributes to the overall capacity and performance of the system.
• Data Striping: Data is striped across multiple nodes, which enhances performance and enables efficient data protection using mirroring or parity.
• Advantages: This method provides high availability, scalability, and performance improvements as the workload is distributed across multiple nodes.

Under the Platform as a Service (PaaS) model, the consumer is responsible for managing applications and data. The service provider manages the underlying infrastructure, including servers, storage, networking, and the platform (runtime, middleware, and operating system). This allows consumers to focus on developing and running applications without worrying about the underlying infrastructure.References:
