A virtual private cloud is a cloud service that offers an infrastructure in which various services (VPC users), of the platform offering it, share resources available in this cloud while isolated from each other. This isolation is usually achieved through having a private local network and subnetting it (could be through VLANs), assigning a subnet to each user, or group of users that need to be directly connected, for other connections a local DNS server can be used.
VPC services usually also encrypt and mask the communication between its users and the shared resources through a VPN, adding as well a layer of authentication. A VPC implements layered security and provides it As-A-Service at the cost that it is highly complicated to set up, but using it correctly can yield a system with powerful defense.
This is a technology that I’ve yet to learn, but will do so, hopefully, this summer. If there are some project ideas that you, the reader, have that may help in my learning of this technology, I’ll appreciate it if you shared them in the comments.
