Scaling

Scaling strategies for Netasampark platform.

Horizontal Scaling​

Application Servers​

  • Load Balancer: Distribute traffic
  • Multiple Instances: Run multiple app servers
  • Session Storage: Use Redis for sessions
  • File Storage: Use shared storage (S3)

Database Scaling​

  • Read Replicas: Distribute read load
  • Sharding: Partition data across databases
  • Connection Pooling: Manage connections efficiently

Vertical Scaling​

Server Resources​

  • CPU: Increase cores
  • Memory: Add RAM
  • Storage: Increase disk space
  • Network: Upgrade bandwidth

Load Balancing​

Configuration​

upstream app_servers {
    least_conn;
    server app1.example.com;
    server app2.example.com;
    server app3.example.com;
}

Health Checks​

server {
    location /health {
        access_log off;
        return 200 "healthy\n";
    }
}

Database Scaling​

Read Replicas​

// config/database.php
'read' => [
    'host' => [
        '192.168.1.1',
        '192.168.1.2',
    ],
],
'write' => [
    'host' => '192.168.1.3',
],

Sharding Strategy​

  • By User ID: Hash-based sharding
  • By Region: Geographic sharding
  • By Date: Time-based sharding

Caching Layer​

Redis Cluster​

  • Multiple Nodes: Distribute cache
  • Replication: High availability
  • Sharding: Distribute keys

CDN Integration​

Static Assets​

  • Images: Serve from CDN
  • CSS/JS: Serve from CDN
  • Fonts: Serve from CDN

Configuration​

// config/filesystems.php
'cdn' => [
    'driver' => 's3',
    'url' => env('CDN_URL'),
],

Monitoring Scaling​

Key Metrics​

  • Request Rate: Requests per second
  • Response Time: Average response time
  • Error Rate: Percentage of errors
  • Resource Usage: CPU, memory, disk

Auto-scaling​

  • CPU Threshold: Scale at 70% CPU
  • Request Threshold: Scale at 1000 req/sec
  • Cooldown Period: 5 minutes

Best Practices​

  1. Start Small: Scale incrementally
  2. Monitor: Track key metrics
  3. Test: Load testing before scaling
  4. Document: Document scaling procedures
  5. Automate: Use auto-scaling where possible
