Ddanzi Group, well-known for one of its services, The Ddanzi Ilbo, transferred all of its services to Windows Azure early in 2013 to secure IT competitiveness to a degree comparable to that of mainstream media outlets. The group's decision to adopt the cloud solution came from its ever increasing numbers of listeners and emerging security threats. In the first half of 2011, its podcast gained so much popularity that some dubbed it a social phenomenon. Such popularity, however, came at a price in terms of the risk from security threats such as DDoS attacks. The group was unfortunately unable to handle either the increasing traffic loads or the threats.
