### JobQueue
|
||
|
||
The heart of this application is a `JobQueue` class that wraps a BullMQ `Queue`. \
|
||
\
|
||
A `Monitor` is considered a job, when one is created it is enqueued in the `JobQueue`.\
|
||
\
|
||
Jobs are handled by a pool of workers in the `JobQueue` and their tasks are executed in the order in which they are enqueued.\
|
||
\
|
||
Workers are scaled up and down based on the jobs/worker ratio as jobs are enqueued and dequeued.

||
### SSL
|
||
|
||
SSL is handled by LetsEncrypt and Certbot. This works by Nginx and Certbot sharing the same volume where the certificates are held. The following snippet from the docker-compose.yaml file shows how this works.\
