Core Architecture Discrepancies
The choice between residential and datacenter proxies is the most critical architectural decision in web scraping pipelines. The core trade-offs lie between speed, trust profiles, and cost:
1. Dedicated Datacenter Proxies
Datacenter proxies consist of static IP blocks hosted on commercial server networks (AWS, DigitalOcean, gigabit servers). They are extremely fast (sub-12ms response rates) and feature unlimited bandwidth downloads. However, because they belong to datacenter subnets, modern security antibots flag and ban them immediately upon crawling guarded commercial directories.
2. Rotating Residential Proxies
Residential proxies route your queries through real home consumer contracts (Comcast, AT&T, BT). While response rates are slightly slower (34ms-50ms) and plans are billed based on GB data payloads, their clean domestic reputation is unmatched, ensuring a near-zero block rate on the most guarded targets.
