The difference between Cloud Database and traditional Database

Cloud database refers to the database that is optimized or deployed to a virtual computing environment, which can achieve the advantages of pay-on-demand, on-demand expansion, high availability and storage consolidation. According to the type of database, it is generally divided into relational database and non-relational database (NoSQL database).

A traditional database is a collection of data organized according to a certain data model and stored in a secondary memory. This kind of data set has the following characteristics: it does not repeat as much as possible, serves a variety of applications of a particular organization in an optimal way, and its data structure is independent of the application program that uses it. The addition, deletion, modification and query of data are managed and controlled by unified software.

After understanding the traditional database, we will make a simple performance comparison between the cloud database and the self-built traditional database:

1. Service availability.

In terms of service availability, the cloud based database is 99.95% available. On the one hand, the high availability version provides a dual-master hot backup architecture to achieve fault recovery of about 20 seconds, and on the other hand, the cloud database can enable read-write separation for load balancing free of charge, which is easy to use. In the traditional database services built by self-purchased servers, it is necessary to build master-slave replication, self-built RAID, separate implementation or purchase of load balancing equipment, etc.

2. Data reliability.

In terms of data reliability, the cloud database provided by Interconnection Pioneer is 99.9999% reliable and supports physical backup and logical backup, backup recovery and rollback in seconds, while in the traditional database service built by self-purchased servers, it needs self-protection, self-built master-slave replication, self-built RAID, and so on.

3. System security.

The cloud database provided by Internet Pioneer can prevent DDoS attacks, clean traffic, and repair various database security vulnerabilities in a timely and effective manner, while traditional databases built on self-purchased servers need to be deployed and expensive, and database security vulnerabilities need to be repaired by themselves.

4. Database backup.

cloud based database can support physical and logical backups, backup recovery and rollback in seconds, while traditional databases built by self-purchased servers need to be implemented on their own. At the same time, you need to find backup storage space and verify whether backups can be restored on a regular basis.

5. Hardware and software investment.

The cloud based database provided by Internet Pioneer has no hardware and software investment and is paid on demand, while the cost of the traditional database server built by the self-purchased server is relatively high, and you need to pay a license fee for SQL Server.

6. System hosting.

There is no hosting fee for the cloud database provided by the Internet Pioneer, while the traditional database built by the self-purchased server costs more than 5000 yuan per year for each 2U server (if master and slave are needed, the two servers need more than 10000 yuan per year).

7. Maintenance cost.

The cloud database provided by Interconnection Pioneer does not need operation and maintenance, while the traditional database built by self-purchased servers requires full-time DBA maintenance, which costs a lot of manpower.

9. Resource utilization ratio.

The cloud database is 100% utilized according to the actual settlement, while the traditional database built by the self-purchased server needs to consider the peak value, and the resource utilization is very low.

From the above comparison, we can see that the cloud database products provided by Internet Pioneer are high-performance, high-security, high-reliable, cheap and easy-to-use database service systems, and can effectively reduce the pressure on users' operation and maintenance. bring users a safe and reliable new experience.
