What is cloud storage?

Whatiscloudstorage?

Nowadays, cloud computing is one of the "buzzwords" in emerging technologies and services, and a new storage model - cloud storage - has been extended from the concept and practice of cloud computing. Cloud storage is coming into our lives through various application services, gradually changing our perception of traditional storage methods, and refreshing the way of file storage.

Various large search platforms need to process more than ten billion times of data every day, and most of them are unstructured or semi-structured data. Therefore, it is urgent to build storage and computing platforms to manage massive amounts of data in an easier way. The emergence of cloud computing and cloud storage can effectively solve this problem.

Cloud computing is an application model that connects IT resources (such as servers, storage, applications and services) through a network to form a shared pool of resources and provide on-demand services to users, while enabling rapid deployment of resources.

Based on cloud computing, cloud storage has been developed. Cloud storage is actually a part of cloud computing concerning data storage, archiving and backup, and is an innovative service. We can understand the definition of cloud storage from two aspects: first, in terms of user-oriented service form, it is an application model that provides on-demand services, and users can connect to cloud storage resources through the network to store data in the cloud anytime and anywhere; second, in terms of cloud storage service construction, it is through distributed, virtualized, intelligent configuration and other technologies to achieve massive, elastic scalable, low-cost, low-energy Second, in terms of cloud storage service construction, it is through distributed, virtualized, intelligent configuration and other technologies to achieve massive, elastic scalable, low-cost, low-energy shared storage resources.

Cloud storage is characterized by high reliability, high availability, high security, standardization, and low cost. These features are achieved by relying on technologies such as distributed access, global access space, virtualization-awareness, data flow capability, intelligent space allocation, and green energy conservation.

From the structural model, cloud storage is mainly composed of thousands of network storage devices, distributed file systems and other storage middleware. Its structure is divided into four layers, from bottom to top, the storage layer, management scheduling layer, application interface layer and access layer.

Like cloud computing, the security of cloud storage has always been a concern, and the first consideration for both enterprises and ordinary users is always its security. Information security response and technical protection is relative, how to protect information security on the basis of providing users with more convenient storage services, but also the focus of the future development of cloud storage technology.
