Leading French operator, SFR has deployed Varnish Software's Varnish Plus solution as the backbone of its private content delivery network (CDN).
SFR Group combines a top-tier fiber optics network and a leading mobile network and aims to rapidly extend its fiber and 4G coverage to every corner of the country while offering optimal service quality. Serving more than 190,000 businesses through its B2B business, SFR also serves 21.9 million mobile customers and 6.4 million households subscribing to broadband services.
With a website that is one of the top-ten most-visited sites in France, SFR needed to reduce the high costs of handling so much traffic. SFR decided that building and managing its own CDN was the best way to reduce costs, bring control in-house and to then offer its CDN solution onward to customers.
Varnish Software said that the better and faster the CDN performs, the more content SFR is able to deliver and the more they can invoice customers. Improved performance has also contributed to their customers' bottom lines by decreasing their infrastructure costs. With the flexibility of Varnish Configuration Language (VCL), SFR can easily tailor its CDN with additional functionality by writing VMODs to extend the capabilities of Varnish Plus.
