Question - What are the main differences between NAS (Network-attached storage) and HDFS?
Answer -
The main differences between NAS (Network-attached storage) and HDFS –
- HDFS runs on a cluster of machines while NAS runs on an individual machine. Hence, data redundancy is a common issue in HDFS. On the contrary, the replication protocol is different in case of NAS. Thus the chances of data redundancy are much less.
- Data is stored as data blocks in local drives in case of HDFS. In case of NAS, it is stored in dedicated hardware.
