According to IDC research, business data storage has expanded continuously at a compound annual growth rate of 3.9%. Global data storage is estimated to expand 50 times larger at the year of 2020. Therefore, how to employ "Information Lifecycle Management" (ILM) has become a must-know in developing cloud-based storage technology and big data structure.

The concept of Information Lifecycle Management is to store application system and a company's most heavily accessed data (certain trivial operations such as searching for e-mails and updating database etc.) in the SSD with the fastest response speed as On-Line storage. The secondary information can be stored in low-priced traditional hard disks as Near-Line storage. As for backups and archives, they can be stored in lower-cost storage media, such as magnetic tapes, as Off-Line storage. Through automatizing the Information Lifecycle Management, the company can reduce over 40% of its Total Cost of Ownership (TCO). The structure highlights the balance between information value and storage costs.
