The recommended best practice for Virtual Private Cloud (VPC) security involves establishing secure connections, and utilizing a transit gateway through a VPN is an effective way to achieve this. A transit gateway facilitates the management of multiple VPCs and on-premises networks, allowing for a central point of control and reducing complexity. By using a VPN to connect to the transit gateway, you establish an encrypted connection that enhances security, ensuring that data in transit is protected from unauthorized access and potential threats.

Connecting to the transit gateway also simplifies the networking architecture, improving scalability and security management as you can manage traffic flow more effectively between multiple network resources. Incorporating VPN security measures aligns with best practices for VPCs as it mitigates risk while enabling secure communication between diverse network environments without exposing sensitive data to the public internet.

Choosing this approach is in direct contrast to the alternatives, which could expose the VPC to vulnerabilities by either allowing unrestricted access, eliminating crucial security measures, or only using public IP addresses without proper protection mechanisms. Each of these options significantly compromises the integrity and security of network communications within a VPC.
