This article mainly explains "what's the difference between cloud database and self-built database". Interested friends might as well take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what's the difference between a cloud database and a self-built database?"

Cloud database refers to the database deployed in the cloud. Is it necessary to use cloud database?

The difference between cloud database and self-built database

Cloud database refers to the database optimized and deployed on the cloud. Both Aliyun and Tencent Cloud provide cloud database. What's the difference between cloud database and self-built database? Is it necessary to use cloud database?

Generally, cloud databases support read-only instances, read-write separation, automatic failover, data backup, Binlog backup, SQL audit, access whitelist, monitoring, message notification and other features.

Today, let's talk about the advantages of cloud database in terms of high availability, high security, Binlog backup, OPS optimization, read-write separation, and so on:

High availability

In general, cloud databases provide instances of master and slave nodes, which can be located in different availability zones in the same region. When the master instance fails, it can be quickly switched to the slave instance to ensure the stability of the cloud database.

High security

Take RDS as an example. Generally, a middle layer is added to the access of a cloud database. All requests will pass through the middle layer, and requests with SQL injection will be blocked by the middle layer. In the underlying data writing, RDS uses the highest security level of writing to ensure that the data will not be lost in the event of an abnormal power loss of the host. In order to ensure the high security of the database.

Binlog backup

Generally speaking, for example, what if the user mistakenly modifies thousands of pieces of data? Use the Binlog backup feature of the cloud database to retrieve it minute by minute.

Optimization of database operation and maintenance

Users do not need to consider database operation and maintenance costs, and enterprises do not need to be equipped with professional DBA database operation and maintenance. Cloud database provides monitoring, alarm, backup, recovery and tuning means. Cloud database can be considered as 0 OPS.

Separation of reading and writing

Cloud database can achieve read-write separation, and users do not need to pay for read-write separation technology, so it is easy to use.

The advantages of cloud databases cannot be compared with those of self-built databases. Of course, some users are worried about leakage when hosting their own databases on the cloud. Novice webmasters suggest choosing large factories, such as Aliyun or Tencent Cloud. Generally speaking, cloud computing vendors will not touch user data, so you can rest assured.

What are the advantages of cloud database RDS compared with self-built database?

Finally, is it necessary to choose a cloud database? For important data, you can choose cloud database. Qualified users are advised to choose cloud database to be more secure and reliable. Of course, they can also be mixed.

At this point, I believe you have a deeper understanding of "what is the difference between cloud database and self-built database". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
