Cloud storage technology and development analysis of cloud computing application revolution

Since the beginning of last year, domestic cloud computing voice is increasing, but the enterprise application is still wool. In 2011 years, the situation has changed a lot, a variety of applications gradually increased, which cloud storage technology first came to our side. Cool disk, Jinshan, Lenovo and so on are launched based on cloud storage technology network hard disk, and Tencent QQ space, security vendors anti-virus software virus database and a variety of online shopping mall has also entered the era of cloud storage.


　　


Apple products have always been good for applications, and many of its online services are based on cloud storage.


　　


while the core of cloud computing and processing is the storage and management of large amounts of data, the cloud computing system needs to be configured with a large number of storage devices, so the cloud is transformed into a cloud storage system, so cloud storage is a cloud computing system with data storage and management as its core.


　　


Cloud Storage has moved to our lives


　　


in contrast to traditional PC users ' habit of installing software on the local computer, handheld device users tend to access Web services more strongly, and Apple and other manufacturers of tablet and smartphone sales indeed for cloud-based services to broaden the space for development. But from another perspective, in the final analysis, cloud services are web-based. Then its development, and network infrastructure is closely related, good user experience from reliable and high-speed network access. So, on the other hand, the wide coverage of 3G and WiFi wireless networks offers an unprecedented opportunity for the online business of handheld mobile devices.


　　


Cloud storage currently for consumer market applications, it is first to provide users with a secure, accessible, easy to share storage space, and security and accessibility itself is a pair of contradictions. Personal users for security concerns, the current relatively few people accept their own important files, privacy files to the cloud to save, the application is mainly focused on the transmission of large files, literature sharing, music and general pictures of the collection.


　　


Enterprise-Class cloud storage applications have also been formed


　　


For enterprise users, cloud storage can not only serve as a storage resource platform for cloud computing applications, but also for the centralized management of digital assets, as well as the consistency of data between different sites that work together, especially for companies that require large project design by branch offices. At present, many enterprise users in security to do a lot of optimization (build a private cloud or VPN) on the basis of the further need for adequate access speed. Online Services can provide many trusted application services such as file sharing, mail management, CRM, accounting, marketing, human resources, and Iaas,paas. are supported by cloud storage.


　　

Compatibility between
clouds needs to be addressed


　　


Cloud is based on the network, service-characterized. Security and network bandwidth, including tariff levels, are critical to cloud development. Under the restrictions of these conditions, very reluctantly to run some applications, does not reflect the advantages of the cloud. In addition, traditional ILM is not deployed to most cloud computing platforms on the market.


　　

The reason for this is that most of the disk media in many cloud computing uses the lowest tier of storage in a typical ILM scenario, which makes it impossible to migrate data to the bottom of the
. This requires the deployment of today's cloud computing platforms to have the foresight to adopt the right storage offerings. In practice, users who deploy compellent often find that subsequent expansions often require only the lowest-tier, lowest-cost storage media, and that the overall performance is not comparable to traditional cloud computing platforms.


　　


In addition, for enterprises, how to transfer existing business systems to the cloud platform is also a key issue, especially in the development of enterprises, the tolerance of the error is limited, there is a need for reliable solutions to avoid the economic loss of difficult to calculate. The compatibility between the clouds is another problem, different cloud service provider's architecture is different, provides the interface also different, the communication between the cloud, is also a future need to solve the problem.


　　


for the enterprise, the decision of it mode comes from the business requirement. How to translate business language requirements into it application requirements and match them with appropriate it technologies and resources is a closer to the essence of enterprise-level users ' view of cloud storage.


　　


infrastructure remains key to cloud storage implementation


　　


Performance does not necessarily require the higher the better, but has a variety of performance areas for users to choose from, but basically to meet the lower latency, the early cloud computing platform due to the neglect of the back-end storage investment in a relatively large number of IO latency.


　　


In addition, 70% of the stored data is static and rarely even accessed again, so companies can save costs by settling the data into lower-cost media through automated ILM (Information Lifecycle Management). In order to do this, you must use a policy-based block-level ILM approach, volume-level and file-level automatic migration can not achieve the desired effect, only granular granularity to the block level, it is possible to apply to the needs of the corresponding. The importance of data protection is not to say that for storage, data security is the first, especially for enterprise users.


　　


In addition, in recent years, storage equipment in the performance of a greater increase. The bottleneck of traditional disk seek speed has long been a major bottleneck of storage performance, the emergence of solid-state hard disk has greatly improved the problem, but because of the cost considerations, often need to do SSD and HDD mixed configuration scheme, automatic tiered storage technology is important to highlight, Compellent is very good at this point. Solid-state hard disk and intelligent data management technology in two aspects of the development of the common accumulation, for the most recent storage innovation has played a major role.


　　


with the rapid development of mobile terminals, online shopping, software mall, network disk storage, space and micro-blog have become an essential application around us, and these applications through the current advanced cloud storage technology can effectively improve efficiency, to the greatest extent to simplify enterprise management while reducing the occurrence of downtime, For the continuous expansion of the application plug the rapid development of the wings. Cloud storage era is coming, are you ready!
