Deploy OAM Server on AWS

[mojodna]

Assuming Docker as a delivery mechanism (#10), investigate ECS and Elastic Beanstalk as alternatives to one-off Docker instances running under CoreOS (or similar), configured with CloudFormation (vanilla or using a configuration abstraction).

I've gotten a bit more familiar with CoreOS, and think using it in a first pass at OAM server deployment is worthwhile. Worst case, we end up deploying Docker on a Debian based operating system as a fallback.

Pros

• Docker storage driver defaults to ext4 with OverlayFS
• Easy path to deployment with systemd unit files via cloud-config
• No real need for etcd or flanneld right away
• We get to freeze node_modules

Cons

• Automatic upgrades could pose a problem in auto scaled environment; may need to disable or schedule
• Lack of packaging system demands that all tooling be containerized (including monitoring, log aggregation, etc.)

Currently reading up on ECS and EB relatively recent support for multicontainer Docker environments. Hoping to add to the discussion about those topics later in the week.

FWIW, here's a CloudFormation config that we use for Toner (no autoscaling implemented): https://gist.github.com/mojodna/327ed929a31a4eb978a4

It disables automatic upgrades, doesn't use etcd, and punts on log aggregation, etc.

Freezing node_modules can also be achieved using npm shrinkwrap.
