My name is Ishita Mahajan and I am a Roopu Cloud Ambassador. In this blog post, I will deep dive into ApsaraDB for RDS and after that, I will show you step-by-step how you can create an ApsaraDB RDS instance for MySQL.

Self-managed databases
Self-managed databases are databases that are hosted on ECS instances. To use self-managed databases, you must purchase a minimum of 2 ECS instances to set up a primary/secondary architecture. Also, you need to pay for the storage that you use. You can only use intranet traffic, to use internet traffic you need to pay for that. In a self-managed database, automated backup is not possible. You need to configure streaming backup and PITR features which will increase your cost. If your Database breaks down then Self-managed databases take about 30 minutes to complete failover.
