Hello,
To leverage scaling and resiliency functionalities of AWS EC2 service, Fleet Manager should use an Auto Scaling Group and a Launch Template to create Dataiku Nodes (Design, Automation, etc).
This would also to better fit with the AWS services management model which will allows to use other services like CloudWatch.
One example of a challenge that will be solved is having Dataiku Nodes be automatically redeployed after an instance or system failure.
