# Our sample application

- Split into 5 microservices
  - `rng` = web service generating random bytes
  - `hasher` = web service accepting POST data and
    returning its hash
  - `worker` = background process using `rng` and `hasher`
  - `redis` = data store for the results of the worker
  - `webui` = web interface to watch progress
