Proxy Fusion Mechanism: Highly Available Architectural Design

What do you do when the proxy pool suddenly explodes?

Engaged in data collection friends have experienced this kind of despair: 3:00 in the morning script running well, suddenly all the proxy IP collective strike, the next day the boss stared at the empty database to say. At this time if you knowProxy Fusion Mechanism, is as solid as insuring the program.

What the hell is this meltdown mechanism?

Simply put, it is to install a "smart switch" to the proxy IP. When an IP failed 3 times in a row (this number can be adjusted), the system automatically shut it down in a small dark room for 15 minutes, while the second cut the backup IP to continue to work. Like driving a spare tire system, flat tire immediately switch automatically, not to give the business breaks the opportunity.

Build your own fusion system?

Don't rush to write code! It's more reliable to use off-the-shelf tools. Take ipipgo'sIntelligent Routing ModuleFor example, their API returns come with theHealthiness Score, just pick the IP directly based on the score. We've also done real-world comparisons:

When using a normal proxy pool, there will be 20% requests stuck when encountering network jitter; after switching to the ipipgo solution with fusion, the failure rate is directly pressed to within 3%. Especially theirCity-level meltdownsFunction, can automatically avoid the entire fault area, this is particularly useful during the double eleven such a big promotion.

Real Life Saving Cases

Last year there was a customer who did a price comparison system, using a certain agent always pumped at 3:00 pm on the dot. We hooked him up to ipipgo's fusion system and set those parameters:

Failure Threshold:3 times/minute
Cooldown:10 minutes.
Regional segregation:Automatic IP blocking in the same city

As a result, the success rate was pulled directly from the original 46% to 92% during the failure period that afternoon, leaving the technical director dumbfounded.

The QA session you care most about

Q: How can I tell if an agent is really hung up or temporarily fluctuating?
A: ipipgo's solution monitors both TCP handshake time and service response time, double verifying before marking a failure, which is much more reliable than just looking at timeouts.

Q: Will business be interrupted during the meltdown?
A: Their system automatically fills in, and the switching time is controlled within 300 milliseconds, which is faster than a human blink (really measured the blink speed).

Q: What should I be aware of when building my own fusion system?
A: Focus on monitoring three indicators:Type of error(4xx/5xx to be handled differently),Response to fluctuations(Sudden slowdown could be a warning),Regional density(Don't put your eggs in one basket). Honestly, though, it's more economical to just go with ipipgo's off-the-shelf program.

Tell the truth.

Seen too many teams in the meltdown mechanism to take a detour, some of the failure to retry the number of times set to 10 times, the result of an IP stuck in the entire queue; some did not do regional isolation, touching the server room failure directly destroyed. Now ipipgo's new user registration will sendFuse Configuration Templates, follow the template to adjust the reference, at least you can avoid the 80% pit.

Lastly, we remind you: don't use free proxies in the fusion system! We have done a stress test, the failure rate of free IP pools is more than 7 times that of commercial services, and even if the fusion mechanism switches faster, it can't hold up to the poor quality of IPs.
