Spin up VPS instances across multiple cities, countries and continents.

Hook them up with Docker and connect them with Swarm.

Label them with an IP/city/country/continent combination.

Use Docker Swarm's affinity labelling to start instances in a particular city when needed. Additionally record the last IPs used and use Swarm to not deploy to those servers.

We scrape more than 120,000 web pages per day.

Cost of spinning up VPS instances, maintaining the software needed (to automatically close/open new ones and provision them) could be higher than the 20$/GB pricing Luminati offers.

I already have the tech after 3 years experience building this. I can rebuild it for you. Contact details in my profile.

I just looked up the cost and no kidding at $20/GB.

I work for Scrapinghub which has a Proxy API which may work for you: http://scrapinghub.com/crawlera

Pricing is a lot less and we only use our own IPs.
