It looks like they wanted to run Mongo inside their own Amazon account- under their direct control. AWS could do that with Postgres while MongoDB couldn't.

That makes me sad. I would love for AWS to have a hosted Mongo solution or some type of NoSQL database besides DynamoDB.

Do people use ElasticSearch as a primary data store? In my limited experience implementations don’t treat it as the source of truth.

Yes, but it only works if absolute-goddamn-integrity is not a concern.

We unfortunately inherited a cluster from someone who thought it would be appropriate as a SoT for forensic data, which causes me no end of grief.

Elastic maintains a page documenting the current status of their "resiliency" efforts on Elasticsearch:

ElasticSearch doesn’t have adequate data integrity to treat it as a primary data store for most use cases.

You could do what they are doing here

What's wrong with running a EC2 instance with Mongo in it?

[lykr0n]

Nothing, but they outline their problems in the article

[flatiron]

they talked about NTP. which to me means Mongo on EC2 maybe?

[lykr0n]

That's what I understood they were doing and they didn't want to do that anymore.

Yep that's what we were doing, and the management software (OpsManager) was also running on EC2 instances. We messed up the VPC configuration so that NTP didn't work on some of the instances - which unsurprisingly broke authentication between OpsManager and the db instances
