Multy

Abstract

1. Introduction

Multy is the easiest way to deploy multi cloud infrastructure

With Multy, you don't need to worry about how resources behave differently in the different clouds providers. We abstract the nuances of each cloud so that moving your infrastructure between clouds is done by simply changing the cloud parameter.

Let's try to deploy a simple virtual machine into AWS and Azure using the Multy Terraform Provider

2. Objective

Multy - Easily deploy multi cloud infrastructure. Write cloud-agnostic config deployed across multiple clouds

This project demonstrates how Go, Terraform, AWS can be applied to a real-world Blockchain & Cloud Computing problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Go 1.20 or later
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/multycloud/multy.git
cd multy

1. Install Terraform - see guide, e.g.:
2. Brew (Homebrew/Mac OS): brew tap hashicorp/tap && brew install hashicorp/tap/terraform
3. Choco (Chocolatey/Windows): choco install terraform
4. Debian (Ubuntu/Linux):
5. Create an account with AWS or Azure and expose
6. Write your configuration file, for example a file named main.tf with the following content:
7. Run terraform init and then terraform apply
8. Run terraform destroy

sudo apt-get update && sudo apt-get install -y gnupg software-properties-common curl
  curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -
  sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
  sudo apt-get update && sudo apt-get install terraform

terraform {
      required_providers {
        multy = {
          source = "multycloud/multy"
        }
      }
    }

    provider "multy" {
      aws = {} # this will look for aws credentials
    }
    resource "multy_virtual_network" "vn" {
      cloud = "aws"

      name       = "multy_vn"
      cidr_block = "10.0.0.0/16"
      location   = "eu_west_1"
    }

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a CI/CD pipeline with GitHub Actions
• Deploy to a public test network or cloud free tier
• Add monitoring and cost alerts

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Why does this problem need a blockchain or cloud-native design?
2. Explain the smart contract / infrastructure components and how they interact.
3. How are gas costs or cloud costs kept under control?
4. How is the system secured (keys, IAM, access control)?
5. How would the solution scale to many more users?
