Cloud Storage: A New Storage Technology in the Cloud Age

Cloud storage is a completely new concept that extends from the concept of cloud computing. It refers to a large number of different types of storage in the network through functions such as cluster application, grid technology or distributed file system Equipment through the application of software together to work together to provide external data storage and business access functions of a system. When the core of cloud computing system computing and processing is the storage and management of a large amount of data, a large amount of storage devices need to be configured in the cloud computing system, and then the cloud computing system is transformed into a cloud storage system. Therefore, cloud storage is a data storage And management as the core of the cloud computing system. In simple terms, cloud storage is an emerging solution that puts storage resources on the network for people to access. Users can easily access data from any networkable device anytime, anywhere. However, while being easy to use, we have to focus on storage security, storage must have good compatibility, and its many factors such as scalability and performance aggregation. First of all, the most important thing about storage is security. Especially in the cloud era, the data center stores the data of many users. If the storage system has problems, its impact far exceeds that of decentralized storage. Therefore, the security of the storage system Sex becomes more and more important. Second, the storage used in the cloud data center must have good compatibility. In the cloud era, computing resources were collected in the data center and distributed to users along with the accompanying storage space, so there was no need to care about compatibility issues from the user's point of view. However, in the data center Angle, compatibility is a very important issue. Many users bring a variety of needs, Windows, Linux, Unix, Mac OS, storage needs to face a variety of different operating systems, if for each operating system is equipped with more specialized storage, no doubt with the cloud Computation of the spirit of the opposite, therefore, cloud computing environment, the first is to solve the compatibility issues. Once again, storage capacity expansion capability.

Due to the large number of users, the storage system needs to store files exponentially. This requires that the capacity expansion of the storage system can keep up with the data volume and achieve unlimited capacity expansion. At the same time, in the expansion process, Good and easy to do, can not affect the overall operation of the data center, if the expansion of capacity requires complex operation, or even shut down, which will undoubtedly greatly reduce data center operating efficiency. Finally, storage systems in the cloud era needed more than just capacity, but were equally as compelling as performance requirements. Unlike in the past, for limited users, in the cloud era, storage systems would be geared towards a broader user base, This increase has necessitated a rapid increase in throughput performance of the storage system, and the only way it can respond quickly to requests is to require storage systems to have a linear increase in throughput as capacity increases, which is clearly traditional storage Architecture can not achieve the goal of the traditional storage system because there is no distributed file system, all access pressure can not be evenly distributed to multiple storage nodes, so there is a significant storage bottleneck between the storage system and the computing system, which And bring a single point of failure and other follow-up problems, and cluster storage is to solve this problem, to meet the requirements of the new age daughter of good.

Cloud Storage Technology and Traditional Storage Technology

Traditional storage technology treats all data as equally important and equally useful to the enterprise, and all data is integrated into a single storage system to meet business continuity requirements. But in the face of big data problems seem stretched:

1) cost surge. In large-scale projects, the front-end image information collection point too much, a single server capacity is limited, resulting in the need to configure dozens or even hundreds of servers. This will inevitably lead to a sharp increase in construction costs, management costs, maintenance costs, energy costs;

2) disk fragmentation problem. Because video surveillance systems often use rollback writing, this disorderly frequent read and write operations, resulting in a large number of disk fragmentation. With the increase of usage time, it will seriously affect the read and write performance of the whole storage system, and even cause the storage system to be locked as read-only and can not write new video data;

3) Performance issues. Due to the surge of data volume, the indexing efficiency of data has become more and more concerned. And easily on the TB data. Even hundreds of terabytes of data often take minutes to index.

As the latest storage technology, compared with traditional storage, cloud storage has the following advantages:

1) easy management. In fact, this one can also be summarized as a cost advantage. Because most of the data is migrated to the cloud storage, all the upgrade and maintenance tasks are performed by the cloud storage service provider, which saves the cost pressure on the enterprise storage system administrator. There is a powerful scalability of cloud storage services, business users grow and develop, suddenly found that their lack of storage space, you must consider increasing the storage server to meet the existing storage needs. The cloud storage service can be very convenient on the basis of the original expansion of service space to meet the demand;

2) low cost. For now, the costs that businesses pay for data storage are substantial, and the cost is rising as data increases. To reduce this cost pressure, many businesses shift most of their data to cloud storage, leaving cloud storage service providers to solve their data storage problems. So you can get the best data storage service with very little price.

3) Tailored. This is mainly for the private cloud. Cloud service providers offer a tailored cloud storage solution specifically for a single corporate customer, or they can be the organization's own IT organization to deploy a private cloud service architecture. Private cloud not only for business users to provide the best quality personal service, but also to a certain extent, reduce security risks.

The traditional storage model no longer meets the real problem of the current data explosion. How to make the emerging cloud storage play its due capacity? We still need constant efforts to solve the problems of security and compatibility. For now, Cloud computing era has come, as its core cloud storage will become the inevitable trend of future storage technology.
