Octane Laravel Package

Technical Evaluation

Architecture Fit

Laravel Octane is a high-performance application server designed to replace PHP-FPM in Laravel deployments. It leverages event-driven, asynchronous servers (Swoole, RoadRunner, FrankenPHP, OpenSwoole) to:

• Boot Laravel once and keep it in memory (vs. per-request booting in PHP-FPM).
• Handle concurrent requests efficiently via worker processes (critical for I/O-bound APIs).
• Support HTTP/2, WebSockets, and streaming natively (via RoadRunner/FrankenPHP).
• Integrate seamlessly with Laravel’s ecosystem (e.g., queues, caching, sessions).

Key Fit Criteria: ✅ High-traffic APIs/SPAs: Ideal for Laravel apps with >1000 RPS or WebSocket-heavy workloads. ✅ Microservices: Enables low-latency responses via async workers. ✅ Hybrid Deployments: Supports Docker/Kubernetes (via RoadRunner/FrankenPHP). ❌ Not for CPU-bound tasks: PHP workers are still single-threaded; offload heavy tasks to queues.

Integration Feasibility

Critical Dependencies:

• PHP 8.1+ (required for Swoole/RoadRunner).
• Composer autoloader must be preloaded (Octane handles this).
• No PHP-FPM (mutually exclusive; use Octane or PHP-FPM).

Technical Risk

Key Questions for TPM:

1. Workload Profile: Is the app I/O-bound (APIs) or CPU-bound (computations)?
   • If CPU-bound: Octane won’t help; offload to queues.
2. Deployment Model: Docker/K8s (RoadRunner/FrankenPHP) or bare metal (Swoole)?
3. Real-time Needs: WebSockets, SSE, or long-running requests?
4. Team Expertise: Comfort with async PHP (Swoole callbacks)?
5. Rollback Plan: How to revert to PHP-FPM if issues arise?

Migration Path

Phase 1: Proof of Concept (PoC)

1. Add Octane to composer.json:

   composer require laravel/octane
   

2. Choose a Server:
   • FrankenPHP: Simplest (bundles Caddy).

     php artisan octane:install frankenphp
     

   • RoadRunner: Most flexible (requires RR server).

     php artisan octane:install roadrunner
     

3. Test Locally:

   php artisan octane:start
   

   • Verify no regressions in routes, queues, or WebSockets.
4. Benchmark:
   • Compare RPS vs. PHP-FPM using ab or k6.
   • Check memory usage (octane:monitor).

Phase 2: Staging Rollout

1. Containerize (if using Docker/K8s):
   • Example Dockerfile:

     FROM laravel/octane:frankenphp
     COPY . /var/www/html
     WORKDIR /var/www/html
     RUN composer install --optimize-autoloader
     

2. Configure Workers:
   • Adjust config/octane.php:

     'workers' => [
         'connections' => [
             'http' => [
                 'options' => [
                     'worker_concurrency' => 10, // Match CPU cores
                     'max_requests' => 1000,    // Restart workers after X requests
                 ],
             ],
         ],
     ],
     

3. Database Tweaks:
   • Add connection cleanup in AppServiceProvider:

     public function boot(): void
     {
         if (app()->runningInConsole()) return;
         DB::disconnect();
     }
     

4. Monitor:
   • Use FrankenPHP’s admin UI (http://localhost:26153) or RoadRunner’s CLI.

Phase 3: Production Cutover

1. Blue-Green Deployment:
   • Route traffic to Octane gradually (e.g., via load balancer).
2. Rollback Plan:
   • Keep PHP-FPM warm until Octane is stable.
   • Use APP_SERVER=php-fpm env var to fallback.
3. Post-Mortem:
   • Review worker crashes (check storage/logs/octane-error.log).
   • Optimize worker concurrency based on load.
