We currently have 3 EC2s serving as Kibana Hosts. We're planning on moving Kibana to Docker followed by Logstash and Finally elastic. Just keeping Kibana in Mind - was curious on the community's thoughts on the basic ECS Setup of Kibana.  
Scenario : Currently 3 EC2 Instances suffice. However in the future we expect greater loads on our instances and want to account for this.

- Should I go DAEMON and create 1 Docker Task per Container?
- Stay as REPLICA And add 2 Tasks per Container?  
How would vcpu and soft/hard memory breakup be suggested per container instance?  
I was thinking 1024 MB for Soft Memory  
vcpu is TOTAL CPU/2 to allow for 2 Tasks to be shared on the same instance.

thoughts?
