Highly Concurrent Business Proxy IP Solution: Architectural Design to Support Millions of Requests

First, where exactly are the million-dollar requests stuck?

Engaged in the crawler or spike system old iron understand, when the request volume rushed to the level of millions, ordinary proxy IP with the morning rush hour like a subway station - squeezing can not be squeezed into. The most common problem is that the IP pool is too small, resulting in high repetition rate, connection timeout, CAPTCHA bombing. To put it bluntly, your IP has not yet entered the door of the website, it was recognized by the security guard (anti-crawling system).

II. Three-tier architecture design method

Let's directly on the dry goods, with three-tier architecture to break the game. Let's start with a real case: an e-commerce company to do competitor price monitoring, every day to sweep the page 8 million times, before using the ordinary proxy every day was blocked more than 3,000 IPs, changed to use our program directly down to 17 per day blocking.

Core Architecture:

Client → Scheduling Center → Dynamic IP Pool → Static IP Pool → Target Site
       ↘ Anomaly Monitoring ↘ Cloud Server Clustering

The first layer is headlined by ipipgo dynamic residential proxies, with a pool of 90 million IPs sufficient to play wheelbarrows. The second layer of static residential agents is responsible for tasks that require session maintenance, such as the collection of login status. The third layer uses their cloud servers to do local caching, CN2 line measured latency can be pressed to 23ms or less.

III. Key configuration parameters

Don't be fooled by the fancy parameters, these are the real deal:

When setting up the ipipgo backend, remember to check the box forCity-level rotationrespond in singingprotocol mixing. The actual test SOCKS5 protocol in the financial website pass rate than HTTP is higher than HTTP about 40%.

IV. Guidelines for avoiding pitfalls

A minefield I stepped on last year while working on a solution for a live data platform:

• Don't use more than 5 sub-accounts at the same time, it's easy to be recognized as a clustered request
• Switching static IPs from 3-6am, the loosest anti-climbing rules at this time of the day
• Don't be hardcore when it comes to CAPTCHA, call their SERP API to take structured data directly

V. Package selection tips

The ipipgo package looks like a lot, but there are really just two types of needs:

High Frequency Acquisition → Dynamic Residential (Enterprise Edition)
Login required → static residence + cross-border dedicated line
Live class → TikTok solution + cloud server

Personally, I would recommend getting the Dynamic Standard version to test it out first, and then switching to the Enterprise version when your usage goes up to 20GB/day. There's a hidden trick to their traffic package - ask customer service for an expansion coupon on Friday afternoon to get 15% more traffic.

QA First Aid Kit

Q: What should I do if my IP is blocked?
A: Immediately cut to a static IP pool and use the city locator feature to switch to a cold area, e.g. Maine has a 3x higher pass rate than New York

Q: How do I determine IP quality?
A: Look in the backstage of ipipgoFirst-time success rateindicator, above 92% counts as a premium line. Then check for a clean X-Forwarded-For field in the HTTP header

Q: How do I choose a cost-effective billing method?
A> Use traffic packs for million dollar requests and pay-as-you-go for less than 100,000 dollars. Their traffic packs are not zeroed out at the end of the month, so you can hoard them for big promotions

VI. Practical black technology

Lastly, I'd like to share a tasty operation: using their cloud server as an IP hopper to disguise proxy requests as normal access. Specific configuration:

 Add the Nginx reverse proxy layer
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

With ipipgo's accurate city localization, it can distribute requests to the exit IPs of 20 different cities, and the measured success rate of letting the anti-climbing system misjudged as natural traffic is as high as 91%.
