NHN Entertainment was established by spinning off the video game business from NHN Corporation (now known as Naver Corporation) in August of 2013. Its key business sectors are online and mobile games. Their challenges are to deploy effective storage and data management solution to support entry into the public cloud services market. They chose NetApp to overcome these challenges. They have implemented a public cloud infrastructure based on NetApp storage and OpenStack software. The results of implementing NetApp were gained efficiency through NetApp FlexClone technology and deduplication, data protection enhanced with NetApp Snapshot technology, high performance delivered with enterprise-level operation of block device and scalability achieved with the ability to non-disruptively scale up to 24 controllers.
