The basic concept of Linux load balancing

First, the main technology of load balancing

1, Cisco Ethernet Channel (Network balance)

2, WINDOWSNLB Technology

3, Linuxlvs Technology

4, F5 and other load balancer (service balance)

Second, redundancy technology

1, CSICOHSRP Hot backup route

2. Windows cluster Technology

3. Linuxha Cluster Technology

4. Ibmaix Cluster

Here are the main explanations for load balancing, clustering, and master-slave differences.

1, Load balancing: The client's request through the load balancing algorithm distributed to different normal operating servers to deal with, thereby reducing the pressure of a single server.

2, cluster: Cluster is mainly to solve the single point of failure, to prevent when a server downtime can not provide services, it is possible to quickly start another server to replace the work, under normal circumstances, a cluster of only one server is normal work.

3, Master and slave: main is to achieve data synchronization, under normal circumstances, the principal and subordinate servers are normal work.

4, the next few days, will be mainly around this topic to expand the record.
