2. It is scalable: Easily adjust resources to meet demand fluctuations.
3. The cost efficiency: Pay-as-you-go pricing with no unnecessary overhead.
4. Integration with Web3: Perfect for projects requiring blockchain integration.
Now, for the deployment process.
✓ Prerequisites
Before starting, ensure you have the following:
- A Cudos Intercloud Account: Sign up on the Cudos Intercloud platform
- SSH Key Pair: For secure access to your virtual machines (VMs.)
- A Backend Application Code: Ensure your server code is ready for deployment (e.g., a Node.js, Python Flask, or Django app)
- Docker Installed (Optional but recommended): Containerize your application for easier deployment and scalability.
- A Domain Name (Optional): For custom domain mapping.
Step 1: Setting Up a Cudos Intercloud Virtual Machine
1. Login to Cudos Intercloud:
- Access the Cudos Intercloud dashboard using your credentials.
2. Launch a Virtual Machine:
- Navigate to the “Compute” section and select “Create Virtual Machine.”
- Choose a suitable VM configuration based on your backend’s resource requirements. For most applications, a basic VM with 2 CPUs and 4GB RAM is sufficient.
- Select an operating system (Ubuntu 20.04 LTS is a popular choice for backend servers).
3. Configure Networking:
- Assign a public IP address to your VM.
- Open necessary ports for your backend server (e.g., port 80 for HTTP and 443 for HTTPS).
- Ensure the firewall settings allow inbound traffic on these ports.
4. Generate SSH Access:
- Use your SSH key pair to configure secure access to the VM.
Step 2: Preparing the Virtual Machine
1. Access the VM via SSH:
```bash
ssh -i /path/to/your/ssh/key username@your-vm-ip
```
2. Update and Install Dependencies:
- Update the package manager and install essential tools:
```bash
sudo apt update && sudo apt upgrade -y
sudo apt install -y git curl unzip
```
3. Install Server Software:
- Based on your backend framework, install the necessary software:
- Node.js:
```bash
curl -fsSL deb.nodesource.com/setup_16.x | sudo -E bash -
sudo apt install -y nodejs
```
- Python & Pip:
```bash
sudo apt install -y python3 python3-pip
```
- Docker (Optional):
```bash
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 Backend Repository:
- Use Git to clone your backend code onto the VM:
```bash
git clone github.com/your-username/your-backend-repo...
cd your-backend-repo
```
2. Install Dependencies:
- Depending on your backend framework:
- For Node.js:
```bash
npm install
```
- For Python:
```bash
pip install -r requirements.txt
```
3. Start the Server:
- Run your application locally on the VM:
- Node.js:
```bash
node server.js
```
- Python Flask:
```bash
python app.py
```
4. Test the Server:
- Access the server using the public IP and port (e.g., `your-vm-ip:5000`)
Option 2: Docker Deployment
1. Create a Dockerfile:
- Ensure your backend repository contains a `Dockerfile` for containerization. Example for a Node.js app:
```
FROM node:16
WORKDIR /app
COPY . .
RUN npm install
CMD ["node", "server.js"]
EXPOSE 80
```
2. Build and Run the Docker Container:
```bash
docker build -t your-backend-app .
docker run -d -p 80:80 your-backend-app
```
3. Verify the Deployment:
- Access the server via the public IP.
Step 4: Configuring a Reverse Proxy (Optional)
To improve performance and security, use a reverse proxy like Nginx.
1. Install Nginx:
```bash
sudo apt install -y nginx
```
2. Configure Nginx:
- Edit the default Nginx configuration:
```bash
sudo nano /etc/nginx/sites-available/default
```
- Update the file with:
```
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;
}
}
```
3. Restart Nginx:
```bash
sudo systemctl restart nginx
```
Step 5: Securing Your Backend
1. Enable HTTPS:
- Use Let’s Encrypt to secure your server with SSL:
```bash
sudo apt install -y certbot python3-certbot-nginx
sudo certbot --nginx
```
2. Set Up a Firewall:
- Allow only necessary ports:
```bash
sudo ufw allow OpenSSH
sudo ufw allow 'Nginx Full'
sudo ufw enable
```
Step 6: Monitoring and Scaling
1. Resource Monitoring:
- Use tools like `htop` or `Docker stats` to monitor resource usage.
2. Scaling:
- For scaling, use Cudos Intercloud’s API or dashboard to increase VM resources or deploy additional instances.
