What is a Content Delivery Network?

A Content Delivery Network (CDN) is a distributed network of proxy servers and their data centers that aims to offer high availability and high performance through spatially distributing service in relation to end-users. A CDN does not fetch content centrally on a single source server, such as one in Tokyo, but instead copies the content onto edge nodes that are nearer to users in Hokkaido or Kyushu. This drastically lowers latency, removes buffering in video streams, and speeds up the load times of a webpage. In the contemporary world, CDNs are no longer caching but critical security boundaries, taking on the role of absorbing DDoS attacks, authenticating API calls, and implementing access policies in the network boundary. CDNs play a critical role to Japanese businesses in overcoming the local internet topography, where most traffic resides in major exchange points in major metropolitan areas to provide a consistent and reliable digital experience, independent of geographic location or network overload.

Use Cases

• Live Commerce & Fashion E-commerce: Live commerce platforms such as Zozo and Rakuten use CDN-based image optimization and dynamic acceleration to provide high-resolution product imagery, which loads in real-time when there are high selling events or influencer live streams.
• Mobile Gaming Rollouts: Japanese game publishers use CDN edge node to provide near-instant distribution of large application binaries and real-time synchronization of in-game events of titles with millions of simultaneous players.
• Broadcaster OTT Migration: Commercial broadcasters migrating linear TV content to OTT platforms use the CDN multi-format transcoding and origin shield capabilities to support large simultaneous viewership during prime-time drama finales.
• Financial Services API Security: Japanese banks and fintech companies use security-oriented CDNs with built-in bot management to secure customer-facing APIs against credential stuffing attacks and to maintain uptime when surges happen in furusato nozei (hometown tax) portal rushes.
