Dynamic Management of OVH Instances in Laravel PHP

In our sale events platform, Auctibles, we use the OVH public cloud to run a dynamic set of compute instances running the LiveKit WebRTC video server. We vary the number of instances based on the number of video-streaming sale events.

As our platform is built using the Laravel PHP framework, we use the php-ovh SDK to manage instances.

We define an OVH service where all interaction with the OVH public cloud will occur.

The Service

use \Ovh\Api;

class OVH
{

    private $ovh;
    private $flavor; // aka VM type based on size
    private $image_name;
    private $datacenter_region_name;

    public function __construct()
    {
        $this->flavor = config('ovh.flavor');
        $this->image_name = config('ovh.image_name');
        $this->datacenter_region_name = config('ovh.region');

        $this->ovh = new Api(
            config('ovh.OVH_APPLICATION_KEY'),
            config('ovh.OVH_APPLICATION_SECRET'),
            config('ovh.OVH_ENDPOINT'),
            config('ovh.OVH_CONSUMER_KEY')
        );            

    }

}

After creating an instance, we launch a job to monitor progress:

WaitInstance::dispatch($instance_id, 'started');
