1, down, indicates that the current server is temporarily not participating in load balancing
2, Backup, reserved machine. When all other non-backup machines fail or are busy, the backup machine is requested, so the machine has the lowest access pressure

load balancing can be effective, then you can find a set of devices to form a virtual whole. In this whole, one is master and the others are backup. These routers use the VRRP protocol to determine the current status, backup upgrade to master, and other information. If master hangs up, select who will be the new master, which can be filtered by the priority configured by the device itself. Sum up: Through

4) fair (a third party) allocates requests based on the response time of the backend server. Requests with short response time are prioritized.
5) url_hash (a third party) allocates requests based on the hash result of the access url, so that each url is directed to the same backend server. The backend server is effective when it is cached.

applications have a limit on the number of CPUs that can be used.
The server acts as a separate entity, which is a single point of failure in the solution. If only one server is responsible for passing the functionality of the component within the application, its failure can cause the application to fail.
Adding servers increases the complexity of managing and monitoring server hardware and its associated software.
