A website supporting tens of millions of PVS is a great test of whether the architecture is mature and robust (this article does not involve the software architecture layer and can be discussed if you are interested ). A system-level architecture is thrown out. It is not guaranteed to be the best solution, but it may be suitable for you. The reason is that excellent architectures are not universal and need to be designed based on the characteristics of each application. We hope to serve as a ref

Analysis of privilege escalation vulnerability using F5 ICall script (CVE-2015-3628)
Earlier this year, GDS found a vulnerability in F5 BIG-IP LTM that allows restricted users to access the system for extraction and remote command execution after successful Elevation of Privilege.This article will show you how to manually exploit this vulnerability. Metasploit has also added corresponding modules. For details, see https://www.rapid7.com/db/modules/exp
hope to serve as a reference, and everyone will participate in the discussion and make comments.

Architecture Description:
1) modules that directly introduce software names in the architecture are recommended by individuals, such as Haproxy and Hadoop;
2) about global load balancing, look at the cost of investment, you can use commercial products, such as F5-GTM, open source solutions is self-built intelligent DNS;
3) Local Load Balancing solution, you can consider F5-

The following are the main features of F5 BIG-IP as an HTTP Load balancer:
① F5 BIG-IP provides 12 flexible algorithms to distribute all traffic evenly to each server, but to the user, just a virtual server 。
(2) F5 BIG-IP can confirm whether the application can return the corresponding data to the request. If a server behind the F5 BIG-IP has a service stop, crash and other faults, f5 checks and marks the server as down, so that user access requests
