The importance of data storage is unquestionable. For enterprises, no matter what industry they are in or what stage they are in, from financial reports to customer information, from user data to business data, they are all crucial and sensitive links. Businesses need to store data in a safe and secure space.
Advantages and challenges of centralized cloud storage
From traditional, bulky paper file storage systems to today's more flexible, efficient and customizable digital solutions, storage technology is constantly advancing . As business grows, enterprises find that the amount of data generated or processed internally and accessed externally continues to increase. The larger the data volume, the greater the complexity of storing, processing, analyzing and retrieving the data. Centralized storage solutions allow users to store data over the Internet and enable remote access anytime, anywhere.
Therefore, it provides easy access across devices, fast movement and rapid deployment, as well as data processing functions such as backup, updates, downloads and more . Of course, enterprises need to pay for the storage services and storage space they enjoy. While storage costs are also increasing day by day, entrepreneurs find themselves facing the following challenges when using centralized cloud storage systems:
Lack of ownership and control
With a centralized storage system, an enterprise's data is stored on a central server on a host computer. Hosts can monitor, censor and even disclose any data to third parties. Naturally, enterprises lose the ability to control and customize their data storage settings. This lack of control and customization creates inconveniences for larger enterprises with more complex data needs.
Data breaches and security risks
Over the past few years, nearly every major industry player has been found to be involved in data breaches . Centralized cloud servers are always located in one region. In the event of a power failure, the entire network may be brought down and unsaved data blocks may be lost.
Increase storage costs
Centralized storage systems eliminate the need for businesses to invest in servers and expensive data storage infrastructure. However, cloud service providers charge exorbitant prices for bandwidth transfer and data security . Additionally, it becomes expensive for businesses to hire experts or migrate from one cloud provider to another. Many business owners complain that 30% of their total cloud computing budget is wasted.
low transfer speed
Centralized servers are located in remote areas, far away from users and enterprises, and distance constraints also slow down transmission speeds .
Of course, we must admit that in the current situation where centralized cloud storage is widely adopted, there is the inevitability and advancement of its birth in the past industry development stage . So far, centralized cloud storage can meet the storage needs of more than one billion mainstream users and large enterprises, and has the advantages of high performance and low cost.
Advantages and challenges of decentralized cloud storage
Enterprises around the world are looking for faster, more secure, private and low-cost alternatives to meet their growing data storage needs . Enterprises in the Web3 industry are turning to centralized cloud storage due to the unique data characteristics and technical requirements of Web3. It cannot fully meet its data needs.
Decentralized cloud storage is also one of the important infrastructures of Web3, providing a more competitive and suitable alternative for Web3. As a builder and innovator in the decentralized cloud storage track, CESS explores and makes breakthroughs in existing decentralized cloud storage technology, proposes and solves the demand for high-frequency dynamic data online storage of Web3 , and can provide Decentralized full-stack solutions are provided for different groups such as large institutions, enterprise-level commercial applications, and individual users .
Greater security and reliability
Unlike centralized cloud storage, which stores all files on a centralized system, decentralized cloud storage uses distributed storage, and security does not rely on any single server, but on each individual server. This increases reliability and redundancy in the event of a failure, making it an excellent way to store personal or business data. CESS has made scientific and effective innovations in the architecture design of distributed storage. It adopts a layered and coupled design approach and is divided into blockchain service layer, distributed storage resource layer, distributed content distribution layer and application layer. Through data slicing technology, massive data can be safely stored .
No centralized control, return of data sovereignty
The prevalence of data leaks and the censorship system in the traditional data storage field reflect the problem of centralized control of data. In the current situation of centralized cloud storage, users do not control the ownership of their data, let alone the consequences of their personal data. income. CESS uses MDRC (Multiple Type Data Confirmation Mechanism) . When users upload data, CESS storage miners will preprocess the data, including digital fingerprint extraction - fingerprint uploading - fingerprint comparison and other processes. The digital fingerprint on the chain will serve as the only proof of data ownership. MDRC can ensure the data ownership of the CESS network and return data ownership to the data owner .
Data privacy protection and rights management
Decentralized cloud storage mathematically guarantees the privacy and security of user data through cryptography instead of protecting it through database network security. User-controlled selective encryption is one of the basic rights of users to master data privacy. By solving the issues of data ownership and data privacy, data ownership is returned to users, allowing users to manage the privacy of their own data. CESS pioneered the multi-type data confirmation mechanism (MDRC) , allowing users to truly control data ownership through data traceability, data maps and data similarity algorithms.
At the same time, CESS pioneered DeOSS (Decentralized Object Storage Service) . DeOSS, as a decentralized object-based mass storage service in the CESS network, aims to provide users with high-frequency dynamic data storage needs with fast reading and writing, high efficiency A secure, scalable and privacy-managed decentralized storage service . DeOSS supports real-time sharing of data online and protects users' data privacy by providing data privacy management and privacy permission classification. Users can decide to make the data they have public, private, or private with partial permissions.
Not only that, CESS also innovatively introduces TEE (Trusted Execution Environment) , which enables data processing to implement encryption, storage proof, decryption and other links under the PoDR² (multi-copy recoverable storage proof mechanism) mechanism , ensuring confidentiality and integrity. To maintain data security and privacy.
Data value links the future
The centralized storage market has now entered a relatively mature stage of development, while decentralized storage is still under development . After describing the above advantages of decentralized cloud storage, we found that the various advantages of decentralized cloud storage have solved the problems currently faced by centralized storage. But it is undeniable that decentralized cloud storage is also facing challenges that need to be overcome, such as continued technological development and iteration, performance improvements such as speed and scalability, and high barriers to entry and participation.
However, decentralized cloud storage still has unstoppable development momentum. This is because decentralized cloud storage promotes the formation of the data value chain and the development of the digital economy era on the basis of returning data sovereignty to users and data security and privacy.
For users, current centralized storage only assumes the storage function, and users need to pay for storage without guaranteeing data security and control. However, as the value of data continues to increase, data storage will gradually evolve into an industrial value chain. Users not only have the ownership rights of data, but also have the right to trade data. CESS supports and facilitates the valorization and value circulation of data . Through proxy re-encryption technology, it allows users to change data ownership without leaking private keys and data content, allowing every user to truly enjoy the value of data.
