Multy is the easiest way to deploy multi cloud infrastructure
Write cloud-agnostic config deployed across multiple clouds.
Let's try to deploy a simple virtual machine into AWS and Azure using the Multy Terraform Provider
variable "cloud" {
type = set(string)
default = ["aws", "azure"]
}
resource multy_virtual_network vn {
for_each = var.clouds
name = "test_vm"
cidr_block = "10.0.0.0/16"
cloud = each.key
location = "eu_west_1"
}
resource multy_subnet subnet {
for_each = var.clouds
name = "test_vm"
cidr_block = "10.0.10.0/24"
virtual_network_id = multy_virtual_network.vn.id
}
resource multy_virtual_machine vm {
for_each = var.clouds
name = "test_vm"
size = "micro"
image_reference = {
os = "ubuntu"
version = "20.04"
}
subnet_id = multy_subnet.subnet.id
user_data = "echo 'Hello World from ${each.key}'"
cloud = each.key
}By using the Multy cloud-agnostic API, we can simply change the cloud parameter to move a resource from one cloud to
another.
If we were to deploy this using the respective cloud terraform providers, we would first need to understand how
resources such as aws_vpc and azurerm_virtual_network behave and how they differ. Then we would need to define the
same infrastructure configuration twice, one for AWS and another for Azure.
This is the equivalent terraform configuration

}With Multy, you write once, and deploy anywhere.
