How It Works

Multy works by deploying infrastructure in your specified cloud provider based on the credentials you provide. Multy translates its cloud agnostic resources into the respective cloud specific resources.

As an example, let's look at a Multy virtual_network resource using the Multy Terraform Provider:

resource "multy_virtual_network" "vn" {
  name       = "multy_vn"
  cidr_block = "10.0.0.0/16"
  location   = "eu_west_2"
  cloud      = "xxx" // (i.e. aws/azure)
}

This virtual_network is then translated so it deploys resources that behave the same way regardless of the cloud. Essentially, Multy will deploy one of the following resources on your account:

AWS
Azure

resource "aws_vpc" "multy_vn" {
  tags = { "Name" = "multy_vn" }
  cidr_block           = "10.0.0.0/16"
}

resource "azurerm_virtual_network" "multy_vn" {
  resource_group_name = azurerm_resource_group.vn-rg.name
  name                = "multy_vn"
  location            = "ukwest"
  address_space       = ["10.0.0.0/16"]
}

Multy also handles the nuances that often happen with two similar resources on different clouds. As an example, the networking of a virtual_machine in Azure is open to the world while in AWS, the default behaviour is private. Multy abstracts these nuances by deploying additional resources, ensuring they have a consistent behaviour. This means a significantly reduced barrier to entry into major cloud providers and the ability to leverage major cloud providers without needing to read documentation in depth.
