Description: The External Virtual Switch in virtualization platforms is an essential component that allows virtual machines (VMs) to communicate with external networks, such as the Internet or corporate networks. This type of switch acts as a bridge between VMs and the outside world, facilitating connectivity and interaction with other devices and services. Unlike internal or private virtual switches, which limit communication to VMs within the same host, the external switch allows access to physical networks, which is crucial for applications requiring constant connectivity and access to external resources. Its main features include the ability to assign IP addresses to VMs, manage network traffic, and implement security policies. Additionally, the external virtual switch can be configured to work with VLANs (Virtual Local Area Networks), allowing for traffic segmentation and improved network security and performance. In a business environment, its use is essential for cloud service integration, server virtualization, and creating test environments that simulate real network conditions. In summary, the External Virtual Switch is a powerful tool that expands the capabilities of virtual machines, enabling smooth and efficient communication with external networks.
