问题 I am a newbie to amazon RDS. I have set up a db instance in RDS. I want to try the RDS read replicas feature. I have few queries: For what kind of applications read replicas are suitable? Is the read replica replicates synchronously or asynchronously data to other read replicas? Is it the substitute of the Multi AZ deployments? How is it better than the master slave or master master replication in MYSQL. If we have replicas on EC2 will it work the same way as RDS read replicas work Thanks in

问题 I have a Saas application on AWS ECS and databases on AWS RDS. We are planning to implement AWS RDS Proxy for pooling implementation. From the RDS proxy documentation, I saw that we don't need to make any changes to the application code. Currently, we are using application side connection pooling.

问题 I'm running an Aurora PostgreSQL (Serverless) cluster. After I deploy the infrastructure for the first time, and every time I re-deploy, I want to run database schema migrations (add tables, add columns). How can I accomplish this? Lambda is out of the question, as migrations may run for a long time. Edit : clarified about schema migration Thanks! 回答1: The correct way to migrate it would be through using the AWS Database Migration Service. You could create the resources in the CDK for this,

问题 I'm working on a project using AWS, hosted on an EC2 instance with a RDS PostgreSQL.
