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.
config {
location = "ireland"
clouds = ["aws", "azure"]
}
multy "virtual_network" "example_vn" {
name = "example_vn"
cidr_block = "10.0.0.0/16"
}
multy "subnet" "subnet" {
name = "subnet"
cidr_block = "10.0.2.0/24"
virtual_network_id = example_vn.id
}
multy "virtual_machine" "vm" {
name = "test-vm"
os = "linux"
size = "micro"
subnet_id = subnet.id
}
If we were to deploy this using Terraform, we would first need to understand how services 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.
