Managing Data Storage in the Public Cloud
With organizations struggling to control costs, they face increasing demands to keep pace with explosive data growth and ever-changing regulations. To address these challenges, storage industry professionals are increasingly turning to cloud computing and cloud storage solutions. Cloud computing is not a new technology in itself - it is a new business model wrapped around technologies, such as server virtualization, to reduce the cost of using information technology resources. This approach offers great potential for the storage and management of data. The advantages of cloud storage are the same as those that define other cloud services: pay as one goes, the perception of infinite capacity (elasticity), and the simplicity of use/management. There are many advantages to using public clouds as part of an organization's long-term storage strategy. However, concerns about security, privacy and vendor lock-in have prevented many users from taking advantage of the benefits of public cloud storage. When evaluating cloud implementations, there are three types to be considered: public, private, and hybrid models (many users implement a combination of these). While the Storage Networking Industry Association (SNIA) is addressing all three types, this paper discusses public cloud storage solutions and the emerging methods available to best manage these environments. With its total cloud storage solution, CDMI is helping users avoid concerns around proprietary public cloud advances and partial solution APIs, helping maintain the integrity of the cloud model.
