Cantos, which provides business-to-business web TV to 45,000 users, has farmed out the processing workload required to render dynamic web content to Akamai using ESI.
Paul Smith, chief technology officer at Cantos, said, "When I joined the company five years ago, we were paying £125,000 a month in web hosting. Now, it costs one tenth of that."
Cantos' eight high-end V100 Sun servers were finding it hard to cope with demand as they needed to dynamically build HTML pages incorporating video, he said.
The site has been re-engineered so that dynamically created content is preloaded, or cached, onto the Akamai infrastructure and scripts running at Akamai render the content.
"It used to take up to 10 seconds for a web page to load, now it takes a fraction of a second," Smith said. Instead of running the Sun hardware Cantos has downgraded to two Linux servers.
