### Edge-Center Provider Configuration and Resource Management

Source: https://registry.terraform.io/providers/Edge-Center/edgecenter/latest/docs

This snippet shows how to configure the Edge-Center provider and define resources such as key pairs, networks, subnets, volumes, instances, and load balancers. It includes examples for creating multiple subnets, attaching multiple volumes to an instance, and configuring load balancer pools and members.
