Automate deployment via CloudFormation

[ryanchard]

We need to encode the web service deployment as a cloudformation script so we can easily bring up new deployments and recover from failures.

We have three major components, the frontend managed with elastic beanstalk, the forwarder and forwarder service running on a a tiny node, and the the redis and RDS databases that act as the glue between these. The component that updates the most is the frontend and that already has a bunch of workflow support in beanstalk. Marginal utility in converting to cloudformation now is limited. If we do migrate from a personal to project account, that might be the point to bite the bullet on this.

I agree. Configuring and linking all the IAMs/security groups/VPCs etc. in cloudformation is a fair bit of work. We should also wait until we land on a long-term approach for managing forwarders. If we switch to EKS or something it'd simplify the deployment process.
