Hosting Keystone JS with MongoDB in AWS?

[Pradeep Gokul]

Hi, there I have been trying to host my keystone site on Amazon Web Service, any thought?

I'm curious to hear how this went. Do you run the app and the DB service in the same VM? Seperate VMs?

We are using AWS and keystone for our project and our infrastructure is similar to this:

1. All our code is baked inside docker containers.
2. We have (depending on EC2 instance) 2-4 containers running behind HAProxy (and ELB in front of it). Depending to environment we have from one to many EC2 instances always active (auto scaling is up).
3. MongoDb is replica set with multiple nodes (separated EC2 instances).

All works like a charm (except when master mongo instance is down, keystone does not reconnect automatically to the new one).

I still don't feel like I understand the nuts and bolts of mongo enough to be comfortable hosting my own instances like that. :p

For small applications I've had no problems running Keystone and Mongo on the same (micro or small) VM in AWS with CloudFlare in front to cache the pages. These were not mission critical apps though and your mileage may vary. Certainly for anything more than a basic app a clustered solution as described above might be much more suitable.
