Description: A virtual switch is a software-based networking device that enables communication between virtual machines (VMs) within a virtualization environment, as well as their connection to external networks. Unlike a physical switch, which requires specific hardware to operate, a virtual switch is implemented in the hypervisor’s software, allowing for greater flexibility and scalability in network management. This type of switch can create multiple virtual local area networks (VLANs), manage data traffic, and enforce security and quality of service (QoS) policies efficiently. Virtual switches are essential in various cloud environments and data centers, where server virtualization and resource optimization are crucial for performance and operational efficiency. Additionally, they allow for network segmentation, enhancing security by isolating different work environments and applications. In summary, a virtual switch is a key tool in modern network infrastructure, facilitating communication and resource management in virtualized environments.
