What parts does the LVS architecture include?

The LVS architecture consists of 3 parts, namely: 1. Load scheduler, which is the front-end machine of the entire cluster to the outside world and is responsible for sending customer requests to a group of servers for execution; 2. Server pool , is a group of servers that actually execute client requests; 3. Shared storage, which provides a shared storage area for the server pool.

LVS Architecture

• # #Load scheduler (load balancer), which is the front-end machine of the entire cluster to the outside world, is responsible for sending customer requests to a group of servers for execution, and the customer thinks that the service comes from an IP address (we can call it a virtual IP address )

• The server pool (server pool) is a group of servers that actually execute customer requests. The services executed include WEB, MAIL, FTP and DNS, etc.

• Shared storage (shared storage) provides a shared storage area for the server pool, which makes it easy for the server pool to have the same content and provide the same service
