This article defines what a VIP is in MCP 1.0. other common names for VIP are: virtual ip address and reverse proxy
Content / Solution:
A VIP (virtual ip address) is an IP address that is not connected to a specific server. Incoming packets are sent to the VIP address, but all packets reach real network interfaces. VIPs are mostly used for connection redundancy; a VIP address may still be available if a server fails because an alternative server replies to connection requests. A load-balanced VIP is a VIP where traffic is distributed among a group of servers. A VIP is also sometimes referred to as a reverse proxy (A reverse proxy dispatches in-bound network traffic to a set of servers, presenting a single interface to the caller).
In the Cloud, a VIP normally consists of a public ip address, protocol, port, and server farm. You can configure your VIP to accept connections on the tcp or udp protocol and listen on ports 1-65535. You can also place your vip 'In Service' to accept incoming connections, place it 'Out of Service' to deny incoming connections, and enable/disable ICMP reply when your VIP is active (has at least one active real server in the server farm).
