Explanation
A virtual private network (VPN) is a security control mechanism that creates a secure and encrypted connection between two networks over a public network such as the internet1. A VPN can help an organization to achieve the desired security for data backup and replication between the data center and cloud by:
* Protecting data in transit from unauthorized access, interception, or modification2.
* Ensuring data confidentiality, integrity, and authenticity by using encryption algorithms and authentication protocols2.
* Providing network access control by verifying the identity of users and devices before granting access to resources2.
* Enabling remote access to cloud resources from any location without compromising security3
