Proxy Pool

Proxy Pool is a collection of proxy servers combined into a single system for distributed use.

How Pool Works

            ┌─→ Proxy 1
Your request ─┼─→ Proxy 2  ─→ Internet
            ├─→ Proxy 3
            └─→ ...

The system automatically:
- Selects optimal proxy
- Balances load
- Replaces non-working addresses

Pool Characteristics

Size

• Small: 100-1000 IPs — for small tasks
• Medium: 1000-10000 IPs — for regular parsing
• Large: 10000+ IPs — for enterprise tasks

IP Type

• Datacenter — cheaper, faster, easier to detect
• Residential — more expensive, slower, look like real users
• Mobile — most expensive, best trust score

Refresh Rate

• Static — IPs don't change
• Dynamic — new IPs added constantly

Pool Benefits

1. Scalability — use as many IPs as needed
2. Fault tolerance — system works even when some proxies fail
3. Simplicity — no need to manage individual proxies
4. Cost efficiency — pay for usage, not per IP

Pool Quality Metrics

• Uptime — percentage of working proxies
• Response time — response speed
• Success rate — share of successful requests
• Geo coverage — geographic coverage
