Answer:
A SAN is made to manage and store data within a local network, whereas a VPN is made to protect data transit across the internet. They are handled by various groups within an organisation and fulfil various functions.
Step-by-step explanation:
1. Function: SAN (Storage Area Network) is used for data administration and storage, whereas VPN (Virtual Private Network) is used for safe remote access to a network.
2. Network: SAN is a type of LAN, whereas VPN is a type of WAN (Wide Area Network) (Local Area Network).
3. Technology: While SAN uses fibre-optic connections and specialised protocols for high-speed data transfer, VPN secures data transmission by using encryption and tunnelling.
4. Scalability: SANs are often less scalable than VPNs because SANs can only be utilised in a single place and are primarily employed in data centres, whereas VPNs can operate over various networks and locations.
5. Price: Because VPNs use existing network infrastructure and do not need specialist hardware, they are typically less expensive than SANs.
