Domestic proxy IP server tutorial: AWS / Google Cloud Practice

Why choose AWS/Google Cloud to build a proxy server?

Nowadays, many technical teams prefer to deploy proxy services using public cloud platforms.AWS and Google Cloud have the widest global distribution of server rooms，日本、德国、巴西这些热门地区都有节点。实测东京节点的服务器能控制在50ms以内，比自建机房省心得多。还有个隐藏优势：云服务商的IP池天然具备可信度，某些平台对云IP的检测相对宽松。

Hands-on deployment of proxy service environments

Using AWS EC2 as an example, focus on three things when creating an instance:
1. Choose Ubuntu 22.04 (best compatibility)
2. Security group opens port 3128 (Squid default port)
3. Selection of target countries by geographic location (e.g., Ohio, United States)

 Install the Squid proxy
sudo apt-get update
sudo apt-get install squid -y

 Modify the configuration file
sudo nano /etc/squid/squid.conf
 Add these two lines
http_access allow all
http_port 3128

 Restart the service
sudo systemctl restart squid

Google cloud operation is similar, but note that the fire rules need to be configured separately. To test whether the proxy is effective, use the curl command:

curl -x http://你的服务器IP:3128 https://ipinfo.io/ip

How to break the fatal flaw of self-built agents?

I often encounter these two problems when I build my own server:
- IP blocking probability up to 60% (especially for repeated use)
- Individual IPs cannot simulate real user distribution
at this momentipipgo's residential IP poolIt comes in handy. Their dynamic IP pool covers 240+ countries, which just makes up for the shortcomings of the single IP of the cloud server. In the crawler scenario, you can first use the self-built server as a scheduling center, through the ipipgo interface in real time to obtain residential IP, so as to ensure stability and avoid blocking.

The golden combination program in the real world

It is recommended to use AWS/Google Cloud Servers as astaging post, for example:
User device → cloud server (traffic encryption) → ipipgo residential IP → target website
There are three benefits to this architecture:
1. Core business servers do not expose their real IPs
2. Request load balancing through cloud servers
3. Automatic change of residential IP to avoid risk control

Q: Will the cloud server traffic cost a lot?
A：建议开启流量监控，业务高峰期配合ipipgo的API切换模式，能节省40%以上的流量成本

Q: Why is the proxy speed sometimes fast and sometimes slow?
A: Check if the server CPU utilization rate is over 70%, and also test ipipgo nodes in different regions. Their intelligent routing system will automatically select the optimal line

Q: How can I prevent my proxy from being abused?
A: Set up a whitelisted IP in the Squid configuration file while using ipipgo'sFingerprint Browser BindingFunctionality, separate browser environments per IP binding

When encountering a surge of CAPTCHAs, it is recommended to add ipipgo to the code layer of theAutomatic threshold switching, a single IP visit over 50 times is replaced immediately. Their API response speed is measured at around 80ms, which is 2 times faster than most service providers.
