VIP

A virtual IP (VIP) is a software-defined IP address that is not associated with a specific physical device, but instead is used to route network traffic to a group of devices or a specific service.VIPs are often used in load balancing and high availability scenarios, where multiple servers or devices are configured to provide redundancy or to handle increased traffic. In such scenarios, the VIP is assigned to a virtual service, such as a website or application, and network traffic is directed to the server or device that is currently available and best able to handle the request.VIPs can also be used to provide a consistent IP address for a service that may be hosted on different servers or devices at different times. By assigning a VIP to the service, clients can connect to the same IP address regardless of which server or device is actually hosting the service at any given time.

Virtual Machine

A virtual machine (VM) is a software emulation of a physical computer system that allows multiple operating systems (OS) to run on a single physical host machine. Each VM operates as if it were a standalone computer system, with its own CPU, memory, network interface, and storage, but all resources are shared from the physical host machine.Virtual machines are created using virtualization software that partitions the physical host machine's resources into multiple isolated environments. Each VM can run a different operating system, allowing for a variety of different applications and services to run on the same physical host machine. This allows for greater utilization of hardware resources, reduced power consumption, and improved flexibility and scalability compared to running multiple physical machines.

VLAN

A VLAN, or Virtual Local Area Network, is a logical grouping of network devices, typically located on one or more physical network switches, into a single broadcast domain. VLANs are created to provide network administrators with the ability to segment a large network into smaller, more manageable groups, improving network performance, security, and manageability.In a VLAN, devices can communicate with each other as if they were on the same physical network, even if they are located on different physical switches. VLANs are configured by assigning ports on network switches to a particular VLAN, and traffic is then separated by VLAN tags, which are added to the Ethernet frame headers of each packet.

VPC

VPC stands for Virtual Private Cloud. It is a virtual network environment that allows users to create a logically isolated section of a public cloud provider's infrastructure. A VPC provides users with full control over network settings, such as IP addresses and subnets.

VPN

Short for Virtual Private Network, VPN is a secure and encrypted connection between two networks over the internet. VPNs are used to provide remote access to corporate networks and to protect online privacy.
