Put in front of the cloud storage "three mountains"

Nowadays, there are some thorny issues in front of it. At present, the main problems that cloud storage faces are broadband bottlenecks, security, availability, and infrastructure.

Broadband bottleneck

Given the widening gap between broadband growth and data growth over the past two decades, broadband is most likely to be the single biggest barrier to cloud storage adoption as a standard commercial application.

Internet broadband upgrade from the original 28.8k modem to about 5Mbps, so much to enhance the extent of more than 170 times. At the same time, however, data growth is much larger than Internet broadband, surging from an average of roughly 100MB per user to over 1TB in the past, an increase of more than 10,000 times. As this gap widens, the viability of offsite storage as the primary means of data storage is diminishing.

Security and availability

In addition to broadband, other limiting factors, including reliability and security, are also on the agenda not to be overlooked. Migration of data to the cloud has given enterprise users a high degree of exposure to their cloud storage server provider for data security and availability. Getting many businesses to migrate their data to the cloud is tough. Worries about security and usability are the supreme element of a company's move to cloud storage.

One is the lack of control over the connectivity of cloud storage or cloud computing resources available on the network. Therefore, the user assumes that all transmitted data may be intercepted or changed. As a result, any sensitive information such as login ID and password should be protected. This security issue is now a cloud service, typically provided by email and CRM owners.

In the past, security was referring to the perimeter security and ensuring that the periphery did not allow unauthorized access. In a virtual world, a physical periphery no longer exists through virtual IT services. Therefore, the business must assume that all transmitted data may be potentially intercepted. There is no physical control of a system, the implementation of these rules must rely on other ways to limit the access to information. Encryption is an important way to limit access to meaningful information. So when IT services are delivered over the cloud, encryption becomes an important part of security. The issue of cloud storage is challenging because data must be stored and stored in encrypted form. If the encryption key itself is lost or corrupted, the data itself is lost or damaged accordingly.

Infrastructure.

Performance does not necessarily require the higher the better, but there are a variety of performance areas for the user to choose, but basically still have to meet the lower latency, early cloud computing platform due to neglect of the rear-end storage and appear more IO delay. In addition, as much as 70% of the data stored is static with little or no access, the business can save money by sinking this data to lower cost media through automated ILM (Information Lifecycle Management) . In order to do this, you must use a policy-based block-level ILM approach. Automatic volume-level and file-level migrations do not work as expected, and granularity can only be fine-grained to block-level . Not to mention the importance of data protection, data storage is the top priority for storage, especially for corporate users.

Solve the above three problems, cloud storage also adapted to the needs of commercial information repository. The initial backup can be done inside the appliance, or it can be backed up on the cloud storage for data protection outside the appliance.
