Outline :
1. Can Mr. Yu share the benefits of going to the cloud and which risk points are unique after going to the cloud?
2. After Mr. Yu goes to RDS on the cloud, will it bring some changes to the maintenance work because the RDS permissions are not completely transparent to users?
3. Teacher Yu has been engaged in database-related work for more than 10 years. Can you share with the young students who are working in DBA about the career positioning of database work for more than 10 years?

Guests introduce themselves
Yu Chengzhen DBA person in charge, DBA person in charge of Shanghai Weimeng Enterprise Development Co., Ltd., senior DBA expert of Weimeng, more than 10 years of DBA working career, mainly engaged in MySQL, Redis and other related business guarantee, performance optimization, architecture design and automation platform construction
01
Can Mr. Yu share the benefits of going to the cloud and which risk points are unique after going to the cloud?
benefit:
a) The complexity of database system operation and maintenance is reduced to 0 (deployment, architecture, backup, monitoring, resource planning, etc.)
b) Technical support of cloud database DBA expert team
c) Can throw the pot, can easily purchase various database solutions (audit, DBBran, disaster recovery, read more, etc.)
risk point:
a) Cloud products inevitably have similar resource contention, system and hardware problems, network problems, etc. These unstable factors affect cloud products/applications; in addition, these problems may not be discovered by the cloud vendor’s monitoring system, or after discovery Failed to notify user
b) In the high-traffic scenario of cloud product standard specifications, the bandwidth may not meet the requirements (taking Tencent as an example, the redis bandwidth is 16MB, the MySQL bandwidth is 1G), this skips the pit
c) The architecture of multiple gateways on the cloud product network cannot be used for QPS in short-chain and low-concurrency scenarios; it is strongly recommended to use self-built test data as samples, compare standard product test data, evaluate product performance, and be well-informed.
02
After Mr. Yu goes to RDS on the cloud, will there be some changes to the maintenance work because the RDS permissions are not completely transparent to users?
Tencent RDS account permissions are already very powerful, and support super permissions. Account permissions basically meet all needs.
03
Teacher Yu has been engaged in database-related work for more than 10 years. Can you share with the young students who are engaged in DBA the career positioning of database work for more than 10 years?
Do not forget the original intention, regardless of self-built or cloud, the basic responsibilities of DBA must be clear, technical ability is the basic.
Mastering a programming language is the "fast lane" for promotion and salary increase. The era also requires development of operation and maintenance needs.
Popular career directions in the future:
Database product architect (go to the hall, go to the kitchen)
Database business operation and maintenance direction
04
May I ask Mr. Yu, can business access be seamlessly switched and rolled back during the database upload process?
The process of database uploading to the cloud uses master-slave replication technology, which can basically achieve seamless switching
As for the rollback, it is recommended that students who go to the cloud do not expect too much. The rollback can be done, but the time cost will be high, and it is not possible to achieve a seamless rollback.
