What Should I Do If an ECS and a TaurusDB Instance Deployed in Different VPCs Cannot Communicate with Each Other?

When a TaurusDB instance and an ECS are deployed in different VPCs of the same region, they cannot communicate with each other through a private network. After a TaurusDB instance is created, you cannot change its VPC.

Solution

  1. Create a VPC peer connection.
  2. Change the VPC hosting the ECS to the same as that hosting the TaurusDB. For details, see Changing a VPC.
