Scaling your VPS

Scaling Your VPS

As your needs grow, you can easily scale your VPS resources. Learn about vertical and horizontal scaling options.

Vertical Scaling (Resize)

Increase resources on your existing server.

How to Resize

  1. Go to your server in the dashboard
  2. Click Resize
  3. Select a larger plan
  4. Choose resize type:
    • CPU/RAM only - Quick, minimal downtime
    • Full resize - Includes disk, requires more time
  5. Confirm and wait for completion

What Changes

Resource Can Increase Can Decrease
CPU Yes Yes
RAM Yes Yes
Disk Yes No*

*Disk can only increase, not decrease

Downtime

  • CPU/RAM resize: ~1-2 minutes
  • Disk resize: ~1 minute per GB

Horizontal Scaling (Load Balancing)

Distribute traffic across multiple servers.

When to Use

  • High traffic websites
  • High availability requirements
  • Separating concerns (web, database, cache)

Architecture Example

                    ┌─────────────┐
                    │   Load      │
                    │  Balancer   │
                    └──────┬──────┘
                           │
           ┌───────────────┼───────────────┐
           │               │               │
     ┌─────┴─────┐   ┌─────┴─────┐   ┌─────┴─────┐
     │  Web 1    │   │  Web 2    │   │  Web 3    │
     └───────────┘   └───────────┘   └───────────┘

When to Scale

Upgrade when you see:

  • CPU consistently above 80%
  • RAM usage above 90%
  • Disk space running low
  • Slow response times

Monitor with:

  • Built-in dashboard metrics
  • htop command
  • df -h for disk space
  • Application performance monitoring

Cost Optimization

  • Start small and scale as needed
  • Use monitoring to right-size
  • Consider reserved instances for predictable workloads
  • Scale down during low-traffic periods
