This article shows you how to achieve storage on the cloud server. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

There are several different ways to store data on the CVM. For the elastic CVM of the website, it can be distributed cluster storage or SSD solid-state disk storage mode, which is chosen by customers according to their needs.

Compared with the traditional storage mode, the distributed storage system has outstanding advantages.

High performance read and write

It can efficiently manage read cache and write cache and support automatic distributed storage to improve response speed by mapping hot spots to caches. Once they are no longer hot, the storage system will remove them. Write cache technology can cooperate with high-speed storage to significantly change the overall storage performance, according to a certain strategy to write data to high-speed storage, and then synchronously set down the disk at an appropriate time.

Consistency of multiple copies

It is different from using RAID in traditional storage framework. Cloud storage uses a multi-backup mechanism, which is sliced before storage, and then stored on nodes in the cluster according to certain rules. In order to ensure data consistency, layout storage usually uses a copy to write, multiple replicas read strong consistency technology, read data failed, get from other replicas, rewrite the replica to restore.

Disaster recovery and backup

The most important means for disaster recovery is snapshot, which can save the data for a certain period of time. It is conducive to fault recurrence, help analysis and research, avoid disasters, backup is for the security of data.

Elastic expansion

Distributed storage can predict and flexibly expand computing, storage capacity and performance. after node expansion, the old data is automatically migrated to the new node to achieve load balancing and avoid a single point of problem. Horizontal expansion only needs to link the node and the original cluster to the same network, and the whole process will not affect the business. when adding nodes, the capacity and performance of the cluster system will expand linearly, and the new node resources will be taken over, allocated or absorbed by the platform.

Storage system standardization

With the development of distributed storage, the standardization process of storage is also advancing continuously. distributed storage at the platform level, by abstracting heterogeneous storage resources, encapsulating the traditional storage device-level operations into storage resource-oriented operations, so as to simplify the operation of heterogeneous storage infrastructure, achieve centralized management of cloud storage resources, and automatically implement the whole cycle process of creation, change, recycling and so on.
