                <=> | (web tier) | <=> | (api tier) | <=>
(load balancer) <=> | (web tier) | <=> | (api tier) | <=> (db)
                <=> | (web tier) | <=> | (api tier) | <=>
                    +------------+     +------------+

The folders web and api respectively describe how to install and run each app.
