What Precautions Should Be Taken When Using RDS?

Updated at: Apr 20, 2020 GMT+08:00
  1. DB instances' operating systems (OSs) are invisible to you. Your applications can access a database only through the IP address and port.
  2. The backup files stored in OBS and the ECS used by RDS are invisible to you. They are visible only in the RDS instance management system.
  3. Precautions after purchasing RDS:

    After purchasing RDS DB instances, you do not need to perform basic database O&M operations, such as applying HA and security patches. However, you must still pay attention to:

    1. Whether the CPU, input/output operations per second (IOPS), and space are insufficient for the RDS DB instances. If any of these becomes insufficient, you will need to change the CPU/memory or scale up the DB instance.
    2. Whether the performance of the RDS DB instances is adequate, a large number of slow query SQL statements exist, SQL statements need to be optimized, or any indexes are redundant or missing.
