The difference between cloud database and cloud server

Cloud server is an important part of cloud computing in infrastructure applications. It is a simple, efficient and flexible computing service. The configuration of CPU, memory and bandwidth can be flexibly expanded. It is generally used to build websites, place applications and deploy environments, and so on.

Cloud database is a kind of database product, which has the function of storing data. We can be regarded as filing cabinets in the cloud-dedicated to storing electronic files, and users can add, query, update, delete and other operations on the data in the files.

In short, database cloud service and cloud server are two different cloud products, which can be used together, but their functions and uses are completely different. A CVM is equivalent to a virtual server. Users can choose different configurations, install various operating systems, and build various environments according to the actual situation. For cloud databases, users can choose to use physical servers or cloud servers to build their own, or they can directly purchase cloud database products from cloud service providers.

In industries that generally use database cloud service, there are often a large number of data that need to be queried and counted quickly, which have high requirements for data security and stability.

For e-commerce platforms, live streaming platforms and online games with high requirements for concurrent traffic and performance, cloud database can easily solve the request pressure caused by sudden access peaks and stably cope with high concurrent traffic.

For the scenarios where banks, securities centers and other financial industries require high data consistency, cloud database can safely store and process financial transaction data and account data to ensure the security of users' financial data and the stable operation of the system.

For small websites / applications that are developed for testing or personal learning, the memory of the CVM itself can fully meet the needs. However, if the scale of the website data expands rapidly in the later stage, the mode that the application is not separated from the database will gradually become unsuitable for use, and even lead to slow response and stutter on the server.

Therefore, it is recommended that we use cloud database in combination with cloud servers and layout websites with separation of stations and libraries. This mode of separation of stations and libraries is faster, reduces data security risks, and reduces operating costs.

With the development of technology, database model is usually divided into relational database and non-relational database. Relational databases are the most commonly used in cloud servers.
