Benefits of NFS
- NFS allows local access to remote files.
- It uses standard client / server architecture for file sharing between all * nix based machines.
- With NFS it is not necessary that both machines run on the same OS.
- With the help of NFS we can configure centralized storage solutions.
- Users get their data irrespective of physical location.
- Enables multiple computers to use the same files, so everyone on the network can access the same data.
- Reduces storage costs by having computers share applications instead of needing local disk space for each user application.

Is cloud better than dedicated server?
Cloud hosting plans offer scalable server resource allocation based on hardware virtualization, whereas dedicated server plans include a fixed allocation of isolated RAM, CPU, and SSD/HDD storage that can provide better performance and increased security for online business applications.
Why is the cloud better than servers?
The data is also stored remotely and never stored on your computer, meaning it is not occupying space unnecessarily. If there are technical issues on site, your data will be safe in the cloud. A final pro is that you can access the data stored in the cloud from wherever there is an internet connection.

What is NFS server?
NFS is used to share files across a network. If you want users on a network to access a common file system that is not local to their machine you can set up a nfs server. nfs is natively built for Unix based machines and it is pretty good. If you want to set up a network share on windows you can look at Cifs/smb. However windows now supports nfs too. As far as setting up a network share server is concerned NFS version 4 is by far the best choice.
Why is NFS so insecure?
Probably the greatest disadvantage is the issue of security. Because NFS is based on RPC, remote procedure calls, it is inherently insecure and should only be used on a trusted network behind a firewall.
Is samba better than NFS?
Is there any other alternative ? : It depends a great deal on your environment. If you are running mostly linux servers then I would use NFS. If you are using mostly windows workstations with a few linux boxes mixed in, then samba would probably be easiest. If you have any Unix then you more or less have to use NFS, especially with older versions. So samba is really best left to Windows interoperability.

What is NFS in Linux?

Can NFS be mounted locally?
Remote NFS directories can be automatically mounted when the local system is started. You can define this in the /etc/fstab file. In order to ensure an NFS file share is mounted locally on startup, you need to add a line to this file with the relevant file share details.
