Project background
Enter the ring:
There are many aspects to the performance of a site. A project is more often specific and needs to be analyzed realistically. Just take an example.
Customer Case:
Case background:
A customer is the main content of the site:
1. Information Portal System
2. Video Search engine Center, Videos Publishing system
3. User SNS Network
4. User Single sign-on SSO center
5. Project Management bug, Customer tracking system, Web calls system
6. Community system: Community with IM, letters and other common systems
7. Separate comment system, for publishing system calls
8. Advertising, hot spot information bidding system, to be linked to all group systems
9. There are related Web calls system, system related data and C/s system in enterprise.
ArchitectureCRM/ERP system has data synchronous transmission requirements ...
10. Additional functional systems at any time based on business development
The above system requires the user Experience program response should not exceed 2 seconds, the number of users registered nearly 100 million people, visit the amount of PV nearly 200 million PV, daily independent IP 3.004 billion IP, peak time maximum of 50000
The number of active users is almost 5 million (two weeks at least one site user)
Number of server devices
Three F5 or LVS.
20 Mainframe Machines
500 around 06 Advanced Server configuration
300 around 08 Advanced Server configuration
There is also a resource,

Project load Balancing architecture principles
Software: Lvs,linux Virtual Server or F5 device Varnish

High Scalability: Hight Scalability

High Availability: Hight availability
-
Manageability : Manageability

Efficiency and affordability:
The main technical blocks involved in load balancing processing are:
1. Payload Scheduler: Load Balancer:
Take user requests to the server node closest to the user according to Geodns and Ipvs
2. Connection pool:Server pool:
Take the user to the request resource server based on the user's request
3. Shared storage: Share Storage:
Resource database, attachment, picture resource requested by user
