Question - What are the key differences between NFS and HDFS?
Answer -
NFS, which stands for Network File System, is a widely implemented distributed file system protocol used extensively in network-attached storage (NAS) systems. It is one of the oldest distributed file storage systems and is well-suited to smaller data sets. NAS makes data available over a network but accessible like files on a local machine.
HDFS is a more recent technology. It is designed for handling big data workloads, providing high throughput and high capacity, far beyond the capabilities of an NFS-based system. HDFS also offers integrated data protections that safeguard against node failures. NFS is typically implemented on single systems that do not include the inherent fault tolerance that comes with HDFS. However, NFS-based systems are usually much less complicated to deploy and maintain than HDFS-based systems.
