Oracle Customer Success—Telenor

Headquartered in Norway, Telenor provides tele, data, and media services in the Nordics, central and eastern Europe, and Asia, with mobile operations as their main revenue driver. They are one of the most popular mobile operators in the world with more than 160 million mobile subscriptions, and with operations in 12 markets.

Ranked #330 on the Forbes 2000 list, Telenor has yearly revenues of more than $16 billion USD/100 billion NOK, 32,000 employees, and is one of the largest telecommunications companies in Europe.

Their DNS Needs
The Telenor content delivery network (Telenor CDN) focuses on the Northern Europe region market, and they have CDN caches localized in data centers in selected continents and regions of the world. With the company’s important role as a CDN, Telenor’s DNS needs were reliable uptime, usability, and the ability to globally load balance their traffic.

The company had been using miscellaneous forms for load balancing, but needed to extend their load balancing functionality with the ability to connect Telenor CDN users to the data center closest to them for better performance. This will become even more important over time as Telenor adds even more data centers in the future.

“We found we could do this the smart way through a managed DNS provider or the expensive way by buying servers, load balancing hardware, and software, and then setting everything up ourselves.

How Did Dyn Make a Difference?
Telenor came on board in the summer of 2013, using both Dyn Managed DNS and Traffic Director, Dyn’s advanced traffic management solution. They instantly began using the Geolocation Load Balancing feature within Traffic Director, giving them more granularity with directing CDN traffic.

“We really like the granularity, and being able to differentiate between different countries and regions of the world. Dyn’s competitors just offer eastern or western Europe or just America,” he said. The Telenor CDN team did consider taking everything in house, but as many companies are finding out, it made more sense to go with an outsourced DNS provider.

“Sure, we have our own DNS services that we also continue to use in some ways, but as a CDN, we needed a more specialized service,” Telenor Service Owner and Technical Manager for content delivery Kjartan Berge explained. “We could have done it ourselves, but we were looking for a partner that provided a global Anycast DNS network”.

Berge added that the three most important characteristics of moving to a managed DNS provider were usability, scalability, and manageability.

“Being able to do everything in the same system versus several subsystems is ideal,” Smeplass added.

With mobile subscriptions and revenues continuing to rise, Telenor Group’s technology staff can be confident that their uptime and CDN traffic management needs are in good hands with Dyn.
