Management

Creating Instances

  1. Choose instance type based on your needs
  2. Select operating system
  3. Configure storage
  4. Add SSH keys
  5. Set up networking
  6. Launch instance

Monitoring

  • CPU Usage: Track processor utilization
  • Memory Usage: Monitor RAM consumption
  • Disk I/O: Check storage performance
  • Network Traffic: Monitor bandwidth usage

Security

  • Firewall Rules: Configure access controls
  • SSH Access: Secure remote management
  • Security Groups: Network security policies

Best Practices

Resource Selection

  1. Right-sizing: Choose instance type based on actual needs

    • Tip: Start small and scale up as needed
    • Warning: Oversizing can lead to unnecessary costs

  2. Storage Planning

    • Tip: Use SSD for frequently accessed data
    • Warning: HDD is cheaper but slower

Cost Optimization

  1. Resource Management

    • Tip: Stop unused instances
    • Warning: Some resources may still incur costs when stopped

  2. Backup Strategy

    • Tip: Regular snapshots of important data
    • Warning: Backups may incur additional costs

Performance

  1. Monitoring

    • Tip: Set up alerts for resource usage
    • Warning: Ignoring alerts can lead to service disruption

  2. Scaling

    • Tip: Plan for future growth
    • Warning: Sudden scaling may require manual intervention
