Hosting - Heroku, Vercel, AWS, DigitalOcean

Perfect — let’s go through hosting Node.js applications on popular platforms: Heroku, Vercel, AWS, and DigitalOcean, including their key differences and use cases.

---

1️⃣ Heroku

• Type: Platform-as-a-Service (PaaS)

• Pros:

  • Easy deployment with Git push

  • Free tier available (with sleep mode)

  • Built-in scaling, logging, environment variables

• Cons:

  • Limited free resources

  • Sleep on inactivity (free tier)

• Deployment Example:

git init
heroku create my-app
git push heroku main
heroku open

• Environment Variables: heroku config:set KEY=value

• Scaling Dynos: heroku ps:scale web=1

---

2️⃣ Vercel

• Type: PaaS, optimized for Serverless and frontend + API

• Pros:

  • Great for Next.js and serverless APIs

  • Automatic CI/CD from GitHub/GitLab

  • Fast, globally distributed edge network

• Cons:

  • Mainly serverless → long-running processes not ideal

  • Free tier has limited execution time for serverless functions

• Deployment Example:

npm i -g vercel
vercel login
vercel

• Environment variables managed via Vercel dashboard

---

3️⃣ AWS (Amazon Web Services)

• Type: IaaS/PaaS

• Popular Services for Node.js:

  • EC2 → virtual machines, full control

  • Elastic Beanstalk → managed deployment, auto-scaling

  • Lambda → serverless functions

  • S3 → static assets

• Pros:

  • Highly scalable and configurable

  • Integrates with databases, caching, messaging

• Cons:

  • More complex setup

  • Cost can increase with scale

• Example: Deploying via Elastic Beanstalk

eb init
eb create my-node-app
eb open

---

4️⃣ DigitalOcean

• Type: Cloud IaaS

• Popular Services:

  • Droplets → VPS (full server control)

  • App Platform → PaaS for Node.js apps

  • Managed Databases → PostgreSQL, MongoDB

• Pros:

  • Affordable and simple

  • Droplets provide root access for full control

• Cons:

  • Manual server maintenance for Droplets

  • Scaling requires manual configuration unless using App Platform

• Deployment Example (Droplet + Node.js)

# SSH into droplet
ssh root@your_ip
# Install Node.js
curl -fsSL https://deb.nodesource.com/setup_20.x | bash -
apt install -y nodejs
# Clone and run app
git clone <repo>
cd <repo>
npm install
node index.js

• App Platform simplifies deployment via Git push
