APEL Server Design
The new APEL server is written in Python. Its design is described in APEL Server Design. It has four components:
- Record loader
- Record publisher
The SSM is the messaging system used by APEL to transmit messages. It is written in Python and uses the STOMP protocol.
This has the fairly simple job of taking the received messages and putting them in the database.
This takes the information from a database and produces messages.
This verifies that the senders of the messages via the SSM are known to APEL.
