FS-Manager
|
Distributed Platform Optimized for UGC Service
FS-Manager has been applied not only in the large portals but also in the smaller UGC service providers. It is well proven in a wide range of Internet environments.
The platform is particularly ideal for smart content distribution, flexible session and storage management required by UGC sites, in which the top 5% of content generates 90% of the traffic.
When a sudden increase of user requests for certain content is detected, multiple copies of the ¡°hit" content are made to allow for an optimum delivery path to the user. The large capacity backup servers can be utilized for this purpose if necessary. When demand drops, the number of copies is reduced to improve the efficiency of system and storage operation, and ensure continued high quality service.
FS-Manager is the optimum platform for UGC service, and its high performance and stability has been well proven through its application by various large portal sites.
