Multiple Server Considerations

HI all,

I’ve used Yii 1.1 for a previous, smaller project, and am now looking to use Yii 2 for a larger community-based project. My question involves scaling Yii out to multiple servers. Are there any considerations with Yii 2 to be aware of? We’ll obviously be using an external database, external session handling (Redis), external Memcache, and external file storage (S3). Are there any other concerns we should be looking at?

Thanks! Would love to hear some stories of how anyone else has done this.
