One note on the Meteor's Scalability. Meteor cannot be scaled with the traditional way we scale apps. Adding more instances does not leads to a scalable meteor app.

Since Meteor gets updates from Mongo. Since one write happens, every instance needs to be get that change as well. In Order to have that, we need to use the Mongo Oplog integration. See more info on that.[0]

Official Mongo OPLOG integration comes with Meteor 1.0 (early 2014), Since then you can use my Smart Collections[1] for Oplog Support.
