Load Balance 产品横向比较

 We can use Load Balance strategy to  increase the system volume .

 

Part 1: LB hardware/software horizontal comparison

the following is the cost and capability estimation:

 

 

Technology	Hardware(H) /Software(S)	Advantage	Disadvantage	Capability (Support how many concurrent sessions)	Cost
F5 BIG-LTM-3400-RS	H	·         Fast Speed (millis-second level) ·         High Availablity(99.9999%)	·         High Cost	>4,000,000	370000RMB
LVS(for Linux)	S	·         Best Performance in Software HB solution ·         Don’t need so many configuration ·         Hot backup solution	·         Don’t support regular expression ·         Can’t support dynamic-static page separation	>100,000	Free
Nginx	S	·         More flexible ,especially support regular expression ·         Less dependency on network, if pings well ,it can do LB ·         Easy install and config ·         Support high concurrency ·         Good technical community support	·         Only support http and email ,it can’t hold session	>10,000	Free
HAProxy	S	·         Can support http ,tcp ,email ·         Can hold session	·         Don’t support apache logging format ·         Need to configure a lot of ACLs	>10,000	Free

 

 

Part 2: My Suggestion

if budget is enough ,we can use two layers:

Layer 1: use F5 (hardware) to load balance every request

Layer 2: use several Nginx server to load balance the request which has been dispatched by Layer 1(F5)
