Integrated load balancing architecture _

Load Balancing service concept

Load effect:

01: the user access request scheduling process

02: pressure reducing web server access

Load achieve:

Implemented in hardware: F5 A10 

Software ways:

nginx: 4 or the use of network layer load balancing 7

Lvs: Layer 4 load network using

haproxy: use 4 or layer 7 load balancing function of the network (a more powerful configuration functions / Web page GUI)

Cluster:

　　Taiwan server to complete the same work (concurrent processing capacity to improve site architecture / architecture more scalable / strong redundancy architecture / infrastructure costs)

　　1): deploy the same software program

　　2): deploy the same software configuration

　　3): Deploying the same website code

Reverse Proxy:

　　Allows extranet users - access - network host server

　　External users -> nginx (direction Agent) - sent to the intranet web server

 

Forward proxy:

　　Allows hosts within the network - access - outside the network host server

Internal network users to access - Proxy (forward proxy) -> foreign server

Load balancing deployment configuration process:

First course: Writing web cluster configuration services
