Can you explain what is meant by Virtual Private Cloud (VPC) in cloud services?

A Virtual Private Cloud (VPC) in cloud services is an isolated virtual network created within the provider's cloud infrastructure (e.g., AWS, Azure, GCP). It allows users to run resources (virtual machines, databases, etc.) in a logically isolated environment with its own network settings, such as subnets, routes, routing tables, and security rules.

Main advantages of VPC:

• Resource isolation from other cloud users.
• Flexible management of network settings.
• Ability to set up VPN for secure connection to a local network.
• Access control through security rules (firewall).

Example: you create a VPC with a subnet for web servers and another subnet for databases, configure routes and security rules so that web servers can access the databases, but external users can only access the web servers.
