Step 1: Launching a Virtual Machine on Cudos Intercloud

1. Sign into Cudos Intercloud: Access your dashboard with valid credentials.
2. Create a Virtual Machine:
   • Go to the "Compute" section and click "Create Virtual Machine."
   • Choose an appropriate VM configuration (e.g., 2 CPUs, 4GB RAM for moderate workloads).
   • Select an OS (Ubuntu 20.04 LTS is recommended).
3. Set Up Networking:
   • Assign a public IP to your VM.
   • Open required ports (80 for HTTP, 443 for HTTPS).
   • Adjust firewall settings to allow incoming connections.
4. Enable Secure SSH Access:
   • Set up SSH access using your key pair.

Step 2: Preparing the Virtual Machine

1. Connect to the VM via SSH:

   ssh -i /path/to/your/ssh/key username@your-vm-ip

1. Update System Packages and Install Dependencies:

   sudo apt update && sudo apt upgrade -y
   sudo apt install -y git curl unzip

1. Install Required Software:

   • Node.js:

    curl -fsSL deb.nodesource.com/setup_16.x | sudo -E bash -
    sudo apt install -y nodejs
   

• Python & Pip:
  

   sudo apt install -y python3 python3-pip
  

• Docker (Optional):
  

   sudo apt install -y docker.io
   sudo systemctl start docker
   sudo systemctl enable docker

Step 3: Deploying Your Backend Application

Option 1: Direct Deployment

1. Clone Your Repository:

   git clone github.com/your-username/your-backend-repo
   cd your-backend-repo

1. Install Dependencies:

   • For Node.js:

    npm install
   

• For Python:
  

   pip install -r requirements.txt
  

1. Start Your Server:

   • Node.js:

    node server.js
   

• Flask (Python):
  

   python app.py
  

1. Test Your Application:
   • Open a browser and access your-vm-ip:5000

Option 2: Docker Deployment

1. Create a Dockerfile (Ensure your repository contains this file):

   FROM node:16
   WORKDIR /app
   COPY . .
   RUN npm install
   CMD ["node", "server.js"]
   EXPOSE 80

1. Build and Run the Container:

   docker build -t your-backend-app .
   docker run -d -p 80:80 your-backend-app

1. Confirm Deployment:
   • Access your server using the assigned public IP.

Step 4: Setting Up a Reverse Proxy (Optional)

For improved performance and security, configure a reverse proxy using Nginx.

1. Install Nginx:

   sudo apt install -y nginx

1. Modify Nginx Configuration:

   sudo nano /etc/nginx/sites-available/default

• Add the following configuration:
  

   server {
       listen 80;
       server_name your-domain.com;
       location / {
           proxy_pass http://127.0.0.1:5000;
           proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection 'upgrade';
           proxy_set_header Host $host;
           proxy_cache_bypass $http_upgrade;
       }
   }
  

1. Restart Nginx:

   sudo systemctl restart nginx

---

Step 5: Enhancing Security

1. Enable SSL Encryption:

   sudo apt install -y certbot python3-certbot-nginx
   sudo certbot --nginx

1. Configure Firewall Rules:

   sudo ufw allow OpenSSH
   sudo ufw allow 'Nginx Full'
   sudo ufw enable

---

Step 6: Monitoring and Scaling

1. Monitor Server Performance:
   • Use tools like htop or docker stats for resource monitoring.
2. Scale as Needed:
   • Utilize the Cudos Intercloud dashboard or API to expand resources or deploy additional instances.
