I realize there are different ways for setting up MySQL database replication when using Alibaba Cloud ECS instances. Which is the best method to use from:

  1. NDB cluster using at least 3 ECS instances
  2. Master-Slave or Master-Master using 2 ECS instances
  3. Using MySQL Group Replication plugin and a set of at least 3 ECS instances.
