Description: A VPC Bastion Host is a special-purpose instance that acts as a gateway to access instances in a private subnet. This type of host is primarily used in cloud architectures to provide a secure and controlled access point to resources that are not directly accessible from the Internet. Bastion Hosts are fundamental for maintaining network security, as they allow administrators and authorized users to connect to private instances without exposing them to unnecessary risks. Typically, these hosts are configured with robust security measures, such as multi-factor authentication and access logging, to ensure that only authorized users can access private instances. Additionally, they are usually located in a public subnet, allowing them to receive traffic from the Internet, while the instances they access remain in a private subnet, isolated from unwanted access. This architecture not only enhances security but also facilitates the management and maintenance of private instances, enabling administrators to perform management and monitoring tasks without compromising network integrity. In summary, a VPC Bastion Host is an essential tool in managing cloud infrastructures, providing a balance between accessibility and security.
