In the era of cloud computing, cloud disks are widely used as a common cloud storage service. When many companies choose cloud disk products as internal file storage and sharing tools, they often enter into a misunderstanding, thinking that buying a cloud disk is buying storage space, and even worrying about whether the company's internal data stored in the cloud disk will cause leakage?
In fact, it is not the case. Enterprise cloud disks are divided into public cloud disks and private cloud disks. These are two common types of cloud disks. What is the difference between them? This article will analyze and analyze from the following aspects.
1. Definition
A public cloud disk is a cloud storage service built on a public cloud platform, usually provided by a large Internet technology company. Public cloud disk is a virtual storage based on cloud computing architecture, which can provide users with data storage and management services through the Internet global network. Private cloud disk is a cloud storage service built on a private cloud platform, which is usually built, managed and maintained by enterprises and organizations themselves. A private cloud disk is a storage system built under the private cloud architecture, which can be carried within an enterprise or organization to provide data storage and management services.
2. Data security
Public cloud disks are supported by large technology companies and have high-strength security measures. Data is stored on the servers of cloud service providers, and its security will be greatly guaranteed and strengthened. However, private cloud disks are self-built by enterprises or organizations. Relatively speaking, their security will vary due to different network environments and security management levels, and enterprises or organizations need to judge and strengthen them by themselves.
3. Price and service quality
The public cloud disk has more excellent technical support and more complete hardware facilities, which can provide better storage and data management services. At the same time, the charging mode of the public cloud disk is flexible, and users can choose the corresponding charging plan according to their own needs. However, since private cloud disks need to be built and maintained by enterprises or organizations, they require higher initial investment and corresponding management costs, and the maintenance costs are also relatively expensive.
4. Scope of use
Public cloud disks usually provide services for a wide range of customer groups such as the public or enterprises, and can be widely used in various scenarios, such as network disks, backups, cloud storage, and so on. Private cloud disks are usually used more for internal data management and control of enterprises or organizations, and pay more attention to data privacy and security.
5. Data storage and transmission
Public cloud disk data storage and transmission adopt virtualization technology, which can realize distributed storage and backup of data. At the same time, the public cloud disk supports multiple protocols and data transmission methods, such as HTTPS, FTP, etc., which can well guarantee the security and stability of file transmission. However, private cloud disk data storage and transmission require enterprises or organizations to build and maintain themselves, so advanced data storage and transmission technologies are required, such as RAID and virtualization.
6. Flexibility
The hardware facilities and various software tools of the public cloud disk can be flexibly configured and maintained according to the needs of customers, so that users only need to pay the corresponding fees to use the cloud disk storage and management services provided by the provider. The configuration upgrade and hardware maintenance of private cloud disks need to be undertaken by the enterprise or organization itself, and a high technical level and professional experience are required to ensure its normal operation.
To sum up, public cloud disks and private cloud disks have their own advantages and disadvantages. Due to its high-intensity security and superior technical support, public cloud disks are more suitable for the application of customers; while private cloud disks are more suitable for internal data management and control of enterprises and organizations. But whether it is a public cloud disk or a private cloud disk, users need to evaluate and choose their own data security.
