This article uses easy-to-understand examples to introduce whether the cloud server will lose data. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

No CVM brand can guarantee that 100% data will not be lost, and Baidu CVM is no exception. As more and more enterprises migrate their business to the cloud platform, it means a significant increase in the responsibility for data security. We need to secure data in the cloud in several ways.

Maintain data integrity

Data integrity can be defined as protecting data from unauthorized modification or deletion. It is easy in a single database because there is only one way to control the entry and exit of the database. However, in cloud servers, especially in multi-cloud environments, because there are a large number of data sources and access methods, authorization becomes critical to ensure that only authorized entities can interact with data. Such as two-factor authorization, and to see who accesses which log records.

Data privacy

Many cloud computing providers may store data on their physical servers rather than in a cloud area, because data owners and laws may be different. This is a problem for users who strictly comply with data residence regulations. Not to mention that cloud service providers may exempt any liability from service level agreements (SLA). If a violation occurs, the user will bear full responsibility. Enterprises should understand the national and international data residence laws.

data encryption

Encryption is a means to protect data privacy, and today's encryption technology is quite mature. Encryption is done through key-based algorithms, keys are stored by cloud computing providers, and some business-related applications use tokenization instead of keys. This involves replacing specific token fields with anonymous data tokens.

In fact, every cloud storage provider encrypts data when it is transmitted. Most of this is done through browser interfaces, although some cloud storage providers use dedicated clients to perform encryption. All of this should be detailed in the service level agreement (SLA). Many cloud computing services provide key management solutions that allow users to control access because the encryption key is in their hands.

Privacy protection

Regardless of an enterprise's cloud computing strategy, it should protect its cloud host data from unauthorized access, including data encryption, and control who can access and view content. In some cases, the enterprise may also want to provide data to some people. For example, developers need real-time data to test the application, but they don't necessarily need to view the data, so they can use an edited solution.

Data security of contract

A service level agreement (SLA) shall include a description of the service to be provided and its expected level of service and reliability, as well as the definition of indicators to measure the service, the obligations and responsibilities of the parties, remedial measures or penalties that are not met, and rules on how to add or remove indicators.

Enterprises do not simply sign service level agreements, but need to read them carefully. Cloud computing service providers do not take unnecessary responsibility for their customers. In addition, service level agreements (SLA) require multiple check marks.

So much for sharing about whether the CVM will lose data. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
