To reduce the load and cost of cloud servers, it is generally necessary to store massive files such as static website resources, pictures, audio and video, logs, and download resources in storage types with lower unit prices, and cooperate with services such as CDN, image processing, media transcoding, and data processing to provide customers with better experience and more services.
What is cloud storage?
Cloud storage is a new concept extended and developed from cloud computing. It is an emerging network storage technology. It enables a large number of storage devices of different types on the network to work together through application software through cluster applications, network technologies, or distributed file systems. A system that provides external data storage and service access functions.
When the core of computing and processing of a cloud computing system is the storage and management of a large amount of data, a large number of storage devices need to be configured in the cloud computing system, and the cloud computing system becomes a cloud storage system. Therefore, the cloud storage system is a cloud computing system with data storage and management as its core. To put it simply, cloud storage is a new way of putting storage resources in the cloud for people to access. Users can easily access data from any time, anywhere, through any connected device connected to the cloud.
Working principle:
Cloud storage is a new concept derived from the concept of Cloud computing. Cloud Computing is the development of Distributed Computing, Parallel Computing and Grid Computing. It automatically divides a large Computing process into numerous smaller subroutines through the network. Then the huge system composed of multiple servers will be calculated and analyzed, and then the processing results will be returned to the user. Through cloud computing technology, Internet service providers can process tens of millions or even hundreds of millions of pieces of information in a few seconds, achieving network services as powerful as “supercomputers”.
Similar to the concept of cloud storage and cloud computing, it refers to the application through the cluster, grid technology and distributed file system function, network of a large number of various types of storage devices set up by applying the software to work together, common external provide access to data storage and business functions of a system, guarantee the security of data, and save the storage space. To put it simply, cloud storage is a new way of putting storage resources in the cloud for people to access. Users can easily access data from any time, anywhere, through any connected device connected to the cloud. If that’s still hard to understand, we can use the structure of the wan and the Internet to explain cloud storage.
Cloud storage functions:
The cloud storage system provides many functions and features designed to meet the storage challenges brought by the growth of massive amounts of inactive data:
· Linearly expand performance and access speed as capacity grows.
· Migrate data stores to distributed physical sites on demand.
· Ensure that data storage is highly adaptable and self-healing and can be stored for many years.
· Ensure privacy and security in multi-tenant environments.
· Allow users to scale performance and capacity on demand based on policies and service patterns.
· Changed the storage purchase model to only charge for the storage actually used, rather than charging for all storage systems, including unused storage capacity.
· End disruptive technology upgrade and data migration.
Advantages of cloud storage:
(1) Storage management can be automated and intelligent, all storage resources are integrated together, customers see a single storage space;
(2) Improves storage efficiency. Virtualization technology solves storage space waste, automatically reallocates data, improves storage space utilization, and provides load balancing and fault redundancy functions.
(3) Cloud storage can achieve scale effect and elastic expansion, reduce operating costs and avoid resource waste;
Problems in the application of cloud storage technology in the security field
Due to the characteristics of security video surveillance services, there are differences between surveillance cloud storage and existing Internet cloud computing models. For example, security users tend to store video information locally, government video surveillance applications are sensitive, video information privacy issues, and video surveillance consumes a lot of network bandwidth.
