What does cloud storage mean?

Cloud storage is a new concept that is extended and derived from the concept of cloud computing. It refers to an online storage model that stores data on multiple virtual servers usually hosted by third parties. , rather than on a dedicated server.

Cloud storage is an online storage (English: Cloud storage) model that stores data on multiple virtual servers usually hosted by third parties. , rather than on a dedicated server. Hosting companies operate large data centers, and people who need data storage and hosting meet their data storage needs by purchasing or leasing storage space from them. Data center operators prepare storage virtualized resources on the back end based on customer needs and provide them in the form of a storage resource pool. Customers can then use this storage resource pool to store files or objects. In fact, these resources may be distributed across many server hosts.

Cloud storage is a new concept that is extended and derived from the concept of cloud computing. Cloud computing is the development of distributed processing (Distributed Computing), parallel processing (Parallel Computing) and grid computing (Grid Computing). It automatically splits huge computing processing programs into countless smaller subroutines through the network. Then it is handed over to a huge system composed of multiple servers for calculation and analysis, and then the processing results are returned to the user. Through cloud computing technology, network service providers can process tens of millions or even billions of information within seconds, achieving network services as powerful as "supercomputers."

The concept of cloud storage is similar to cloud computing. It refers to a large number of different types of storage devices in the network that are gathered together through application software to work together through functions such as cluster applications, grid technology or distributed file systems. , a system that jointly provides external data storage and business access functions to ensure data security and save storage space. Simply put, cloud storage is an emerging solution that puts storage resources on the cloud for people to access. Users can connect to the cloud through any internet-enabled device at any time and anywhere to conveniently access data. If this explanation is still difficult to understand, then we can borrow the structure of the wide area network and the Internet to explain cloud storage.

Main purpose:

Cloud storage usually means placing primary data or backup data in an uncertain storage pool outside the enterprise, rather than placing it in a local data center or a dedicated remote site. Proponents believe that by using cloud storage services, organizations can save investment costs, simplify complex setup and management tasks, and put data in the cloud to make it easier to access data from more places.

Data backup, archiving and disaster recovery are three possible uses of cloud storage.

"The cloud came about mainly for any kind of large-scale storage needs of any kind of static type data." "You don't want to store your database in the cloud, but you probably want to store your database in the cloud." A copy of history, rather than storing it in expensive SAN or NAS technology."

"A good overview is to think of the cloud as cloud storage that can only be used for latency applications. ." "Backup, archive and batch file data can be handled well in the cloud because a delay of a few seconds in response time can be tolerated." On the other hand, she noted that due to the presence of latency, databases and "any performance-sensitive" Its data is not available for cloud storage.

But before migrating data to the cloud, whether it is a public cloud or a private cloud, users need to solve a more fundamental problem.

"If you get into cloud storage, can you understand where or why the growth of storage space gets out of control, and when it comes to storing a particular set of data throughout the end-to-end business process? What's the value point? Simply moving technology to the cloud is not the best solution."

Reducing effort and expense is a major reason why cloud services are expected to continue to grow over the next few years. According to research firm IDC, 4% of global IT spending is spent on cloud services; by 2012, this proportion will reach 9%. Due to cost and space pressures, data storage is well suited to cloud solutions; IDC predicts that cloud storage will increase from 8% to 13% of cloud services spending during this same period.
