"Running a BitTorrent site can be quite costly. Most of the larger sites need over a dozen servers to keep everything running smoothly. There are some scalable alternatives for BitTorrent startups though. Two relatively unknown meta-search engines have taken a different route by using Google’s App Engine, which provides optimal scalability, for free"
"V0rtex and TorrentTab are two sites using Google’s resources to search for torrents. By using Google’s App Engine, they can run their sites without having to invest a single dime in hardware or bandwidth. On a free account, users of Google’s App Engine can host 500MB data, and serve up to 5 million page views a month. This is more than enough for a medium sized BitTorrent site. At the moment it is not possible to upgrade these limits, since paid accounts are not yet available, but this might change in the future.
Both sites are totally ad free, and great resources to search for torrents. V0rtex currently searches 12 BitTorrent sites, including established sites such as Mininova, The Pirate Bay and isoHunt. The site itself has a clean look and feel, and the search results are sortable by date, peers, seeds and more."
