ECS Initial Setup
Enable Elastic Container Service (ECS) for AWS when creating a DuploCloud Infrastructure
Setting up an Infrastructure that uses ECS is similar to creating an Infrastructure that uses EKS, except that during creation, instead of selecting Enable EKS, you select Enable ECS Cluster.

Add Infrastructure page with Enable ECS Cluster selected
Up to one instance (0 or 1) of an ECS is supported for each DuploCloud Infrastructure.
Creating an Infrastructure with ECS can take some time. See the Infrastructure section for details about other elements on the Add Infrastructure form.
