The most important thing to buy a CVM is to choose the right "real cloud". Do not be confused with the real one by some bad merchants, and the phenomenon of selling dog meat by hanging a sheep's head exists in many industries. So how can I buy a real CVM?

A simple way is to look at how data is stored, because this is the essential difference between real clouds and false clouds.

Providing ultra-high reliability for data is one of the fundamental reasons for the emergence of cloud computing technology and its popularity all over the world. Only based on the network, can data be written into multiple copies, achieve decentralized storage, and lay the foundation for avoiding single point of failure and dynamic migration.

While the fake cloud is just an ordinary vps, the data is stored on the local hard disk and the eggs are only in one basket. The risk of machine failure and data loss will always exist, and users can only hope that this machine is reliable and stable enough.

Fake cloud service providers generally only list product models and prices, without more information on the underlying architecture and storage methods, while real CVM providers will provide detailed architecture description, storage methods, comparison of advantages, and so on. For example, Aliyun is based on its self-developed Feitian platform, and elastic cloud is integrated and developed on the basis of open source KVM+Hadoop.

Therefore, by distinguishing how the data is stored, users can buy a real CVM.
