Backup is very important to us. Whether it is at work or in life, there will always be some very important things.These things are best recorded, so as to remind us, so that we can not forget.So what is the difference between a cloud database and an on-premises database?
Cloud database and local database
I. Performance
Cloud database: MySQL's local SSD disk instance has excellent performance, and MySQL's computing performance is even more significant; local database: requires the cloud disk planning structure of the cloud server, and it is difficult to implement the cluster version, which is highly dependent on senior database administrators;
Second, Security
Cloud database: protection: whitelist, security group, VPC isolation; local database: protection: whitelist, security group, VPC isolation; slower than cloud computing hardware update speed, performance is generally lower than cloud database; It is difficult to separate computing and storage (if high-end storage is used to separate computing and storage, tens of millions of expenditures are often required), and it is difficult to implement the cluster version, which is highly dependent on senior database administrators.Cloud database: high data reliability, automatic active and standby replication, data backup, log backup, etc.; cloud server self-built database: high reliability can only be achieved under a good architecture, and R&D services need to be purchased separately.
Cloud database and local database
Three, the advantages of cloud database
Data is the core of all businesses. In order to manage, analyze and mine the value of data more effectively, cloud databases are essential.Compared with self-built databases, cloud databases are more economical, more professional, more efficient, more secure, and easier to use, allowing users to focus more on core business.Ruijiang Cloud provides a full set of services for cloud database disaster recovery, backup, recovery, monitoring, etc. It supports automatic multi-node backup, and supports one-key recovery of backup data. Users can monitor the operating status of the database in an all-round way and upgrade and expand capacity at any time as needed to solve enterprise problems.The troubles of database operation and maintenance.
The difference between cloud database and local database is very clear. Compared with other data storage, cloud database is a very good software. If you are still struggling, then choose cloud database.
