Seems a bit expensive assuming each shard gets you three more servers. Based on RS pricing you could build your own instances with 1TB SSDs for like $500 each, so for the same price that you'd get 100GB x 3 shards you could do 1TB x 3 shards on your own. I guess with the RS pricing you also get managed backups but IMO that's not worth the price difference. If you figure you build your own, 3 shards x 3 RS members x 1TB is 9 servers at $500 each or $4500. With this service... if 100GB is $1599 you have to imagine 1TB has to be at least on the order of $10k, so you're looking at $30k total. $25k a month for managed backups and infrastructure just doesn't seem worth it to me. Maybe what they're using is more powerful than the instances we're on but I still have trouble reconciling the pricing. And if that 1TB is 1TB total and not 1TB per shard/replica set member then the pricing looks way, way worse.

Rackspace did an evaluation of the various mongodb hosted solutions before buying out objectrocket.. Its worth a read http://developer.rackspace.com/blog/benchmarking-hosted-mong...

TLDR, for hosted mongodb its pretty awesome (ssd hardware in direct connect locations, tuned and managed).

That's an awesome link, thanks. Does a lot to clarify where the pricing disconnect is between spinning up my own servers in the RS cloud and using ObjectRocket.

IMO RS's ObjectRocket pages should do a better job showing what you're getting on top just deploying to a bunch of RS cloud servers with SSD's in them.

Mason55, I work for Rackspace. The ObjectRocket service does not run on the cloud servers you get from RS. It's actually a different architecture just for MongoDB: flash drives all over, containers, pretty much tuned for MongoDB across the stack. While we don't describe the full details of the architecture, you have a very valid recommendation that we will take into consideration to make sure it is clear what you are getting for your money. Thanks.

Thanks for the additional info, great to have someone from RS chime in!
