Are there any alternatives meteorhacks:cluster? The project was abandoned about 3 years ago, It only works for meteor versions <=1.5. Do you guys know any other meteor clustering solutions?
You could just use multiple Meteor servers with a load balancer (and sticky sessions). Phusion Passenger may also be a good option https://www.phusionpassenger.com/library/indepth/meteor/request_load_balancing.html
