Fortinet's firewalls secure Yahoo! Japan's data centres

Fortinet’s FortiGate-3700D firewalls enable the company to efficiently process massive connections and manage logs while securing the content delivery network platform.

Yahoo! JAPAN Corporation has implemented Fortinet's FortiGate-3700D firewalls for the content delivery network platform (CDN) in its data centres.

Yahoo! JAPAN has been operating its CDN across its data centres in Kanto and Kansai, supporting an aggregated bandwidth of 40Gbps. It also uses a portion of the service infrastructure to support other initiatives, such as Yahoo! JAPAN News and Auction.

To cope with the rapid adoption of smart devices as well as the increase in traffic volume and session/connection numbers driven by rich content, Yahoo! JAPAN decided to build a new CDN with a bandwidth network of 200Gbps.

To handle the growing traffic, the company required a firewall that wouldn't act as a bottleneck while it protected the network. The desired firewall needed to:

  • efficiently process massive connections and manage the logs resulting from large-scale events, such as the Soccer World Cup;
  • secure the CDN by providing traffic visibility through logs and analysing security event logs;
  • have a minimal footprint and low energy consumption due to the space restrictions within the data centre.

After comparing and reviewing firewalls from multiple vendors, Yahoo! JAPAN decided on Fortinet's FortiGate-3700D high-performance firewall. To achieve the required 800K cps, Yahoo! JAPAN built a CDN system with four sets of eight units of the FortiGate-3700D in both the Kanto and Kansai data centres. This configuration made possible high-speed throughput and connection processing by allocating 80Gbps both uplink and downlink with the core switch.

Shinji Yoshinaga, Manager, Network Security, Infrastructure Engineering Department, Site Operations Division, Yahoo! JAPAN Corporation, said that the FortiGate-3700D "performed exactly as expected." He added that the solution is "cost-effective and allows the company to be ready for IPv6."
