Scaling your app on Heroku ensures it can handle increased traffic and workload. Here’s a guide to effectively scale your application:

📈 Automatic Scaling

Heroku automatically scales your app based on traffic:

  • 📊 Metrics like request volume and response time trigger scaling
  • 🔄 Dynos scale up/down dynamically during peak/off-peak hours
  • ⚠️ Always-on dynos maintain 24/7 availability

🧱 Manual Scaling

For predictable traffic patterns, use manual scaling:

  1. 📋 Log into your Heroku dashboard
  2. ⚙️ Navigate to the "Resources" tab
  3. 📈 Adjust dyno hours via the "Scale" button
  4. 📁 Add Procfile configurations for custom processes

📊 Monitoring & Optimization

  • 📈 Use Heroku Metrics to track performance
  • ⚙️ Optimize database queries with Heroku Postgres
  • 📦 Consider background workers for async tasks
